Car charger and the TV output availability are some of the most highlighted customer favorable features provided in this phone model. Sony Ericsson C905 available in Night Black, Ice Silver, Copper Gold and Tender Rose colors. Another important feature is that the hardware capability. In the general environment, the phone manufacturers change the port formats and the types for each device. But the Sony Ericsson C905 ports can be used with the other hardware, supported by several other models as well. This was an early release as all Sony Ericsson C902, C903 and C905 models were introduced within six months.

With the implementation of the Horizontal menu it has given more space to the user. It contained a navigation wheel in the early versions of the Sony Ericsson and the accuracy was less than the new rectangular navigation menu. A common complain that had with the previous editions of the Navigation Menus was that the lack of water resistance. That can be reduced with this type of a navigation menu. The long living battery and the power consumption techniques increase the efficiency of the usage of the phone. There are power saving facilities available for the usage. Power can be saved by several ways. Brightness control, Bluetooth and Wi-Fi saving are the best ones among them. Number of Bluetooth accessible devices is being restricted to one with the power saving functionality.

Cyber-shot 8.1 Mega Pixel Camera

8.1 Mega Pixel camera can be named as the most valuable option of the phone. It is the first time this kind of quality camera came with a personal phone. In addition there are options available to reduce the size as well. The 8.1 Mega Pixel image is higher than 2 Megabytes and it allows the zooming without any distortion for a long. The Xenon Flash Light with 3-LED video light gives a better light for the images. The night mood images are much better than the Blackberry Curve 8900 and the LG KU990. The flash light can lighten for more than 10 meters and give a better quality picture. Face detection and Smile Shutter options also available with the latest software version for Sony Ericsson C905.

The lens protection is also enhanced with the mechanical lens cover that has a slider and push back cover in it.

But, the Sony Ericsson C905 phone comes with a Walkman headset although it is not a walkman phone. It also includes a FM Radio as in several other versions and the Play Now 5.0 application.

GPS Navigation

Global Positioning System has been a promising implementation for the mobile phones in the recent past. Enabling GPS and Google maps has made the phone much useful for consumers. The ‘Wayfinder Navigator 7’ is an application provided for the tracking purposes. It helps the users to manage journeys, calculate distance and several other features.

Bluetooth And Wi-Fi

Bluetooth is a common option in the mobile phones over a time. Sony Ericsson C905 is not only providing the general factors that are available. The remote controller application connects several devices such like computers and projectors using Bluetooth. Wi-Fi is the latest trend for the mobile phones. Though it has being for the mobile devices such as laptops, notebooks from a long time, mobile phones were facilitated very recently. The latest update for the Sony Ericsson C905 gives the Apple iSync support which was only supported by MAC OS before.

Competition With Other Models

LG KU990 is a much cheaper and recently introduced phone that can gives some features like this. It has a 5 Mega Pixel Camera with the Xenon Flash that gives bright and good looking images. In addition its video frame rate is four times greater than the video frame rate of the Sony Ericsson C905. The LG KM900 Arena is also an upcoming model to give a good competition to this model. It has the dual display function in it. LG KM900 model is slim and also provides the touch screen availability. Therefore the next Sony Ericsson ‘C’ model will have to give a good competition to lead the market. It is a well known fact that the mobile phone is not just a phone today. It is a combination of several other features as well. Those other feature implementation should be well done more than it is now. Sony Ericsson can give a good competition to the business level mobile phones as well. Most of the Sony Ericsson ‘C’ series users wait for a good implementation that could compete with the iPhone in the near future.

Google always surprise us with their amazing products. They offer us keyword search, image search, video search, Maps, Gmail and many other services. If you take a look at the list of Google products you will be amazed by the wide area that they are covering, not only online, but also desktop applications, mobile applications, enterprise solutions and even hardware. If you go out and do a general research among your friends, you will realize that most of them are only using very few Google services and only general features of them. They are not aware of most of the amazing, yet totally free Google products and their fine features. This article will take a look in to 5 amazing Google products and their fine features.

Image Search

I’m pretty sure that most of your friends have used Google Images search. Easy way to access it is do a normal search and change it to image search from top bar or side bar. Once you go to image search it will display thumbnails of images indexed from many web pages, which makes Google image search world’s largest image hug. Using the side bar you can narrow down your result by image size and time.

The main problem in many other search engines is that they don’t actually recognize the content of the image. They just read the ‘title’ and ‘alt’ tags and list the image. This is where Google image search makes a difference. It actually looks in to the image and identify some content of the image for indexing. Therefore you can search image for color.

Ex: You search for “BMW 320i” and then select “Red” color from the sidebar. See the result, it will give what exactly you are looking for.

Then you can narrow down your search by image type. Here again Google image search look in to image and identify the content, whether it’s a face, photo, clip art or line drawing. Try to narrow down the search with type “face” and take a look. You will be amazed by the accuracy of the filtering algorithm.

So far we were using keywords to find images. But Google Image search works the other way around too. You can upload an image, and then it will look for it in the web. To proceed with that you have to go to Google Image home page and click on the camera icon in the search box. It will ask you to upload the image, then it will show you the places where the uploaded image appears on the web. Furthermore it looks in to the image content and present you the visually similar images as well. Same as in the previous case, the image recognition and indexing algorithm works perfectly. To make it easier to use Google image search you can add a description to image as well.

There is a mobile application which allows you to take a photograph using your mobile smart phone and upload it to image search easily, named Google Goggles. You can find more information about the application here. It’s again using the same algorithm to identify the image content and do the search based on that.

Video Search

Google Video search is also commonly used as same as Google Image search, yet its fine features are rarely used by general users. Easiest way to access the video search is do a general keyword search and change the result in to videos using top bar or side bar or Google Video home page.

Any Google search support Voice Search and you can use the same to image or video search. All you have to do is click on the microphone icon in the search box and speak what you need to search to the attached microphone. It will convert that to text and do the search for you.

If you don’t like matured content in your image or video search result you can switch on the “Safe Search” using the drop down menu at the top right side of search result. You can make the safe search strict or moderate according to your requirements.

Google video search doesn’t recognize the content in the videos like image search. Yet, it gives you the facility to narrow down your search result using upload time, duration of the video, quality and source website.

By clicking on the thumbnail of the video you can directly go to source website and enjoy the video.

Google Scholar

Google Scholar is a very special type of search engine which index Academic papers submitted by scholars all around the world. This might not be a quite useful tool to general users, but valuable for academic students. This is the world’s largest hub of academic articles. Right next to search button in Google Scholar Home Page, you can find two links for Preferences and Advanced search. They allow you to fine tune your search result by giving your default preferences and narrow down search result by giving specific searching criteria. In the search result it shows the academic paper or the book section related to search keyword. Further it shows the other articles which already cited the subject article along with related articles which will help you to enrich your forthcoming academic paper.

Sometimes there are articles in databases where you need paid membership to read. In such cases Google will list only the introduction page. To proceed you have to get the membership. If you are an academic student, in most of the cases your university will give you the relevant access to paid article databases.

Google Public Data Explorer

This is again very uncommon type of search engine and hardly ever used by general Google users. If you take a good look in to Google Public Data Explorer, you will be able to find useful information and statistics about your country, or the globe. This is maintaining various different data sets collected by different organization. By accessing a dataset you can see statistical data in graphical format including charts.

Ex: Dataset: World Bank, World Development Indicators -> Gross Domestic Product

Here you can see the total GDP in world and using the side bar you can select a specific county. Further, you can select more than one country to compare the values. Upon your selection, the chart will change real time. You can change the chart type in top left corner.

Google Finance

Google Finance is a specialized search engine which gives you latest market quotes and news from financial world. It collects trading data from many stock indexes and presents it in graphical format. The best part is numbers are changing real time when market opens. So you can get most up to date idea about stock prices along with the latest news.

This is a good place for an investor to do a historical analysis of price patterns and collect valuable information for a strategic investment.

In the search box you can enter a company name or short code in relevant stock index.

Ex: If you want to search for Apple Inc, you can enter “Apple” or “AAPL”

This will take you to the stock prices of Apple Inc along with the chart. Chart provides you a range of options to see historical price patterns and trade volumes. By going to ‘setting’ just under the chart you can change the chart style and intervals. If you are an experienced investor, you will probably change the chart style to “Candlestick” and set the chart interval according to your trading system. By visiting Technicals you can include indicators which helps you to do technical analysis such as Moving Average Convergence and Divergence (MACD) or Bollinger Bands. In here you can include more than one indicator to make this platform an advanced technical analysis tool.

This is a slight insight to uncommon Google products, their fine features and strengths. This makes us realize how far Google has come in information technology market and how it dominates the whole world. Within a short period of time it has changed the global life style and made our lives easier. The important thing here is, no matter how big they are, no matter what kind of monopoly they hold, most of their valuable services come free and they earn money with advertising. Hats off for this smart business model!

Google Maps is the best online global map without doubt. It was developing with latest technologies as well as latest details of the globe for the past few years. As a result it offers us features that no other traditional map offers such as satellite view, voice commands, navigation and street view. Most of the people use this kind of advanced maps for navigation, to search places around them and for other scientific applications, for an example, surveying land. Further, they let the users to update their local maps which is called “crowd sourcing”, and helps the Google Maps to be up to date than any other online map. Usage of Google Maps became  easier with the introduction of mobile applications which gives us an even better user experience than the web interface. It was available for many mobile platforms and most of the updates were available for Google’s Android Mobile Platform.

However, when you try to enter a building, at the door step Google maps leaves you alone. In the building you have to use a conventional printed map to find where you want to go. This is a very unpleasant experience to Google Maps users. The latest release, Google Maps 6.0 for Android solves the problem.

How It Works

When you are using Google Maps you can zoom in to see more details. Normally, zoom in stops at a certain level of detail. But when you are using new Google Maps, if there is a building with the floor plan you can zoom further in to see the indoor details of the building. Same as street details you can see names and description of indoor shops and offices if they are available. And of course you can search for them as well. This comes in handy when you want to quickly find the wash room in a huge air port. GPS technology is capable of measuring altitude, so the application is capable of changing the floor automatically as you move up or down. And there is a side bar for you to change the floor levels manually in case you want to take a look at the floor plan without going there. There is an online demo published by Google which explains the operations in graphic details. See the below video as well.

Is GPS Accurate Enough to Track Me in a Building?

The next big question, most of the time there is a light blue circle around the pointed location on Google Maps, which represent the accuracy. In other words you can be anywhere in that light blue circle. Furthermore Google maps gives you a numeric representation of accuracy as well, like 10M. Is this enough to pinpoint me in a small building?

The simple answer is YES! If GPS is accurate enough to keep you on the right lane on the right road, it should be accurate enough to point you usefully in a small building as long as you have strong GPS signals.

The next question, “I have heard that GPS signals are weak inside buildings. So how can they be strong enough to point me accurately?”

There is a serious point, that signals get weaker when they go through buildings, especially through concrete. Therefore you might face difficulties about the accuracy of the positioning in a building. In other words, when you go to Nike store Google Maps will say you are near GAP store. But most of the time you will get 5-10M accuracy which is way enough to find the location in any small building.

This issue is beyond the Google Maps control but they have done their best. It is more of an issue with GPS satellites and their signal strength. What Google Map does is get the location details from your handset’s built in GPS device and present them in the map. Mobile handset manufactures will keep looking for solutions to capture the weak GPS signals, And there is always a hope that scientists will come up with new innovative technologies for Global positioning.

Where the Floor Plans Comes From?

You already know that you can edit the Google Maps by yourself. After moderation and verification, the changes you did will appear in the public map. This is what they call “Crowd Sourcing”, let public to develop the details of Google Maps.

In the initial version of Google Map 6.0 for Android has covered many important buildings by Google themselves. And again, further development is crowd sourced. You can add your building in here following below four steps.

Locate: Search you your building and locate it on the Google Maps. Drag and drop the marker to the middle of the building. If you are using Satellite view, this will be easier. Then proceed to upload.

Upload: After selecting the building you can upload the floor plan. As information you have to give the building name and floor label as mentioned in the elevator.

Align: In here you have to align the map with the Google Maps. For that they are giving 3 marks, to tell the Google Maps how to align the floor plan with the map.

Submit: Finally submit the floor plan for moderation and verification. After that it will appear on Google Maps, for everyone.

Here is a video released by Google Maps which explains the procedure of adding a floor plan step by step.

What Can We Do With This?

Travelers Support

This new feature of Google Maps opens many opportunities to the business world, majorly for Travel industry. Travel agents like to let their customers to be free during a journey. But in most of the cases there has to be a travel guide and travelers who purchase the package will have to follow him, which is not a good experience to travelers. Recently I have seen, travel organizers give a tablet device to travelers with Google Maps and they can be freely travelling in a certain area with the support of the map and GPS without travel guide around. Yet, it was limited , since there was no Google Maps for Buildings’ floor plans. If one traveler lost in a shopping center,it is huge time delay and bad for business as well. Solution again was a “Travel Guide” which leads back to the same problem.

However this new feature solves it all. Travel agents can let the travelers to be free even in a building with their Android tablet without a travel guide. It will be a positive experience to the travelers and good for the business as well. As long as Google Maps comes for free, Travel agent won’t have to spend extra for this. This will be an advantage for shopping tour organizers who send travelers to Singapore and Malaysia. However, they have to make sure the Google Maps have the updated floor plans of the required buildings.

Business Promotion

I have used Google Maps to find local business many times. But if a business office is located in a building and in the 3^rd floor, I will run in to a big problem. At the same time the business owner also facing a problem, why his customers can’t find him in Google Maps.

With Google Maps 6.0 for android, this problem has been solved and open new opportunities for businesses owners. They can list their office located in a building even with accurate floor level. So his customer can easily search and find the location of business. And most of the business web site embeds Google Maps in their web site. Now that they can embed the Map with floor pan of the building and floor level as well.

Google continue to surprise users by expanding its capabilities beyond the World Wide Web. It has already reached the mobile software market and dominated it defeating previous empires. Google’s Android is the most used mobile operating system today and moving on with frequent updates and developments. Google Maps 6.0 with indoor view will definitely add extra color to Android world and will be a good strength to stand tall among other mobile platforms, showing the power of “Free and Open Source”

In the year 2010 the Smartphone war continues and many manufactures compete to gain more market territory. The most significant product was iPhone by Apple Inc and they successfully reach the market becoming the most selling product. However the major contributing factor for their success is not only their technology but the creative marketing campaign with their well known brand name “Apple”. While iPhone get the whole public attention, most of the people didn’t get to notice other cool products which there in market sometimes for much lesser cost. LG was one of the high tech Smartphone manufacture introduced many cool product to the market with high end technologies.

Down the time with Smartphone, the main requirement that users were demanding were their speed. The reason behind this is many people partially replace their Lap top computer with these devices. So they need the speed as good as Laptop. Before 2011 most of the time Smartphone were having like 1GHz single core processor which is way behind compared to Laptop.

In early 2011 LG come in to the market with exceptional Smartphone and that was named as “LG Optimus 2X P990”. The name says it all. After this earth witness a dual core Smartphone which is speed almost same as an average Laptop. This attracted lot of public attention in that time. Over a less than one year of time, this device changes the global expectation of a Smartphone. Actually it redefined the standard for a mobile device by making lots of impossible things possible.

Features and Functionalities

Processor and Hardware

The main attraction in this device is its processor. It’s Dual Core Cortex A9 Processor with 1GHz clock speed. This platform let you run many applications in the same time due to outstanding multi-tasking capability.  And it comes with GeForce graphic processing unit and Tegra 2 chipset. This GPU let you to connect this device with HD TV to mirroring video. This specification picture a Laptop in my mind not a Smartphone. Surely this device will be a huge threat to Laptop sales. It’s having on board 8GB storage for contacts and SMS with 512MB RAM. Additionally there is a card slot support microSD chip up to 32GB. Phones dimensions are 123.9 x 63.2 x 10.9 mm and 139g weight.

Display

This is one of the most important features in any Smartphone. Here is it 16 million colors LCD with multi touch sensitivity. Size is 480×800, 4 inch, pretty much standard for android Smartphone, yet approx 230 pixels per inch which is great. The touch sensitive screen is protected with denser glass, called Gorilla glass. To identify the user’s motions there is Accelerometer and Gyro meter together, same as in latest iPhone. And there is a Digital compass as well. These sensors could be used to display auto rotate and more sensitive gaming applications as well. To support the operating system function there are few hardware keys at the bottom of the display.

Multimedia

This handset comes with excellent multimedia capabilities. Its supports all common video and audio formats long with image formats. If you want to mirror your HD video in TV there is a HDMI cable comes with. According to many individual reviews on internet HD video playback is very sharp and less nosy. The audio play back with loudspeaker is quality enough, yet nothing outstanding compared to other Smartphones. However there is a 3.5mm audio out gives you total flexibility to extend your audio experience with 2X, may be by connecting your home theater audio system. This audio and video out comes in handy when you play games with the device. Further the device support advanced video compression like DivX, Xvid, H.264, MP4 and WMV. Unlike in many other Smartphone, this support Adobe Flash player version 10.1, so you won’t miss your favorite YouTube.

Camera

LG Optimus 2X is equipped with two cameras. Front camera, 1.3 mega pixel for video conferencing and it works pretty well for self portrait, as a digital mirror as well. The very special one is the rear camera. It is 8 mega pixels with LED flash, importantly the lens is covered with outer glass for protection. This is capable of capturing images with resolution 3264×2448 pixels. This is having advanced auto focusing system with, face detection and touch focus. To reduce the image blurring due to camera shake there is a digital image stabilizer system. Whenever GPS signals are available it attaches GEO tag to the image as a Meta data. Further the rear camera is capable of capturing 1080p HD videos in 24 fps and if you need 30fps you can go down to 720p resolution. The video looks professional and sharp enough to any online publishing.

Operating System

The device originally comes with the famous open source mobile OS Android version 2.2 and it’s upgradable to version 2.3 as well. Same as in any other Android Smartphone, its gives you versatile control over user interfaces and other functionalities. Further it allow you to install JAVA application, which open your device to millions of free world of applications. If you take a closer look you will see that standard android home screen is altered in LG Optimus 2X. Generally almost all the application loads faster in here than any other android device, due to the advanced hardware platform. And touch responsiveness and navigation is also pretty fast. However there are some identified bugs in the software in LG Optimus 2X, probably due to the non optimized source code in OS lead to application crash. And there is another complains from the users that phone is consuming more memory just to load the OS. These things had made this great device unpopular.

Connectivity

Today, the phone is only a feature in a Smartphone. So, people don’t talk much about the GSM connectivity to make telephone calls. Yet it’s very important, since the major usage of the phone is make calls and send SMS though there are 100s of other features. LG Optimus 2X comes with all the modern connectivity, to make phone calls as well as Data. It support quad band GSM including 850/ 900/ 1800 and 1900 for conventional phone calls and SMS. Since most of the applications require data connectivity and of course you need to browse on the run it gives you 3G connectivity with HSDPA. Other than this it comes with Wi-Fi and Bluetooth connectivity as well. To connect the device with PC to sync data there is a Micro USB version 2.0 port, cable comes with the package.

Market Impact

Price Curve and Guinness Record

Normally sometimes after introducing a phone to market, its prices get reduced to certain level and get stabilized. But with LG Optimus 2X it didn’t happen that way.  According to cellpex.com price curve, it’s same today as the launching month. That represent continues demand to the device throughout the time. However this trend might get disturbed due to serous software issues in the operating system. And LG Optimus 2X could make its mark on Guinness Record book becoming “First Smartphone with Dual Core technology” which is amazing milestone for LG.

iPhone

The main competitor of LG Optimus 2X would be famous apple iPhone 4S which having almost same functionalities. However no Smartphone could compete with the iPhone so far in the market, not because of technology, but because of highly creative marketing campaign. At the same time LG Optimus 2X having the disadvantage of software bugs which is having only a patch as a solution. Other than that LG Optimus 2X having advantages like JAVA applications and Adobe Flash player to stand over iPhone.

HTC Android Devices

At the same time it will have to compete with the other Android phones like HTC. They are already doing well in market and gradually become a threat to famous iPhone as well. According to the market statistics, if you consider the number of HTC Android handset sales, it has already surpassed the number of iPhone sales.

The LG Optimus 2X having the advantage of be the first in the market, yet it won’t be enough to continue to survive. LG will have to take bold steps to correct the minor software issues which become bigger problems to usability. I’m pretty happy with their hardware, probably the best hardware for the Smartphone available in the market. With the solution to their software issues they will be able to give good competition to iPhone and HTC and capture significant market share down the time. And I’m curious to know what the next big Smartphone move of LG.

Microsoft’s next most expected product Windows Phone 7 has unveiled at Barcelona’s Mobile World Congress last month. Windows Phone 7 is based on Windows kernel CE 6 while the current Windows Mobile version is based on kernel CE 5. It has planned to release on the holiday shopping season of this year. It has finger based touch screen input system and the UI has named as ‘Metro’, it looks like Zune and Xbox components including 3D effects and transition animations. It includes support for Microsoft Outlook and Office support as well as licensing to a wide variety of third party hardware vendors. However, the multitasking and copy & paste will not support for 3^rd party applications.

Technical Specification

• Screen resolution will be 800 x 480(WVGA)
• Following hardware buttons are required for WP7: Start, Back, Bing integrated Search button, Camera and Power button. Some vendor devices can have more buttons than these five. But, these are required.
• Capacitive multi-touch with support for minimum of four contact points.
• A Qualcomm Snapdragon CPU with DirectX 9 graphics support and the platform is flexible enough to expand in future, according to Microsoft.
• 256MB of RAM
• Currently 8GB of internal Flash storage, but no support for microSD cards.
• WiFi support
• AGPS
• Accelerometer
• FM Radio
• 5 MP camera with flash

The ‘Metro’ interface is a type-and-motion heavy interface based on primary colors and lots of minimal, negative space, and this will be a familiar interface for Zune HD users. It has large, bold text that trails off the screen, menus which move dimensionally in and out instead of just side to side, and the sense that you are panning over long, single pages of information, rather than a set of separate panels. The clean, sharp ‘tiles’ which dominate the home screen, completely lacking in any real world-inspired bevels, drop shadows, curves of textures,  dialer, and alphabetical search grid, which looks like they’ve been built out of separate parts from Tempest. There are two themes basically boil down to light text on a black screen and it is the default theme of the OS and dark text on white screen, and you can pick your choice of four accent colors: red, orange, blue and green.

The phone unlock screen includes time, date, upcoming calendar events, number of unread messages, and number of missed calls. When the screen unlocked, it shows the user-configurable and movable ‘tiles’. The tiles can be linked to an application, a specific contact or a website, a photo gallery, playlist. But you can link anything with these tiles. It has an automatic tile sorting system as the user’s favorite list.

Multitasking And Notifications

The Windows Phone 7 series can process only the Microsoft’s core apps in the background. Third party applications cannot run in the background, and it supports push notifications enabling third party apps to send updates to the home screen even when another application is running. As a reason, Microsoft’s says, it eats a lot of battery life.

Page States

The OS support for page states, which is similar to cookies on websites. It is a light weight package that can easily be kept in memory to preserve the look and feel, and data of an app while discarding the memory heavy UI elements. When the app is needed again after the user navigate away from the screen, it reconstructs to its previous state and this process is called ‘dehydration’ and ‘rehydration’.

Hubs Strategy

Windows Phone 7’s Hub strategy is a unique feature for the platform. From the People Hub, you can manage your various mail accounts and social networks in a single view. You can set status updates and check mails in single place, rather than changing applications. The Picture Hub helps you to access your locally stored photos or cloud based social network picture galleries, upload pictures and comment on them. They offer photo editing functionalities as well. The Game Hub is integrated with Xbox Live, where you can use your avatar in there, and Xbox Live games and achievements, Spotlight feeds, and the ability to browse gamer profiles. The Zune HD is your Music + Video Hub in the Windows Phone 7. You can download new music over WiFi and 3G. You can rent or purchase videos as well. Microsoft is working with Pandora to integrate with the hub, utilizing the Zune player to tap into Pandora’s streaming services.

It has its built in Internet Explorer browser, but it’s not fast as mobile safari.

The business people always love Microsoft Windows mobile, as it has many stunning features, and it has a great support for office tools. Windows Phone 7 has great features with multimedia support and the users will love this lot more than before. In near future, we can expect some wonderful add-ons and application for the new product. Most of the games are developed with XNA support and lot of silverlight features has added to it.

History

Flat File System

A Flat File is a database that stores the data in a plain text file. Each line of the file stores a single value. Each field is separated by delimiters such as commas or tabs. Although it can have multiple tables, it cannot have multiple relations as the Relational Databases have.

Relational Databases

The main advantage of Relational Database over the Flat File System is that the proper organization of data that has. A relational database also defines the relationships between those tables. In the relational databases, queries are used to fetch data with the help of the indexes. The relational database technology makes the databases efficient, lighter and faster. Some of the advantages of the relational databases are;

• Bringing tables together using relations
• Provides a structure query language (SQL) to define and manipulate data.
• Security

Object Relational Model: It is also a relational data model but with object orientation in it. It reduces the gap between the conceptual data modeling techniques and object-relational mapping.

Object-Oriented Database

An Object Oriented database is a combination of objects in a persistent storage which holds information. It is quite similar to the object oriented languages. It can be named as the fifth-generation database technology that was began to develop in mid 80’s.  The real world entities are represented like an object in the Object Oriented Data Model.

Multidimensional Database

It is a database system that can be used to utilize the advantages of the databases. It is usually structured to optimize online analytical processing and data warehouse applications. The multidimensional database can receive data from a variety of relational databases and structure the information into categories and sections that can be accessed in number of different ways.

Sub Modules

Engine

There are several tasks done by the DBMS. It accepts various logical requests from various other DBMS sub systems. Then convert those requests into their physical equivalent and actually access the database and data dictionary as they exist on a storage device.

Data definition and manipulation

In Structured query languages, they have four different operations mainly to operate data. They are Select (Retrieve data from a table/tables), insert (insert data to the tables), update (update a certain field of a column) and delete (delete rows). In addition to them there are several other commands for creating, dropping databases, etc…

Administration

The database administration means the maintaining the functionalities and managing the DBMS. There are 3 main types of Administration. They are

• Operation Administration
• Development Administration
• Application Administration

There comes several tools for the database administration and they are called as native tools.

Other services

Security: The security of data is the most important thing. A DBMS allows to let several users to access the database up to several extends. In addition to that the DBMS allows setting passwords. In addition to that the DBMS allows setting passwords. Encrypting the data is another security feature provided by the advanced DBMS.

Disaster recovery: Database Management Systems allows its users to maintain backups. It makes easy to recover when there is a crash of data. In addition to that most of the DBMS provide role back to a previous state in order to undo transactions in a given period..

Indexing: Indexing makes the operations such as insert and update easy. The data is ordered randomly and the way how it was ordered is described by the logic Indexing speed up manipulation of data since it keep a summary of mata date and it make the SQL engine to access the required data without searching whole database.However indexing doesn’t seep duo the data manipulation in the case the query is conditional, like ‘select name from student where age

Within a couple of years the cell phone evolved in to a Smartphone. Today it has become a day to day item for most of the people. Technological improvement made by lots of Smartphone manufactures such as Apple, HTC, Samsung and LG made this possible. You may remember that, when you were using a cell phone you had to charge it may be once in few days…. 

So far I talked about Processor and Storage options in Smartphone and clarified lots of confusing marketing jargons. Now I believe you can have a better picture about the Smartphone after you read its official technical specification.

Quick Catch-up

Now we are moving forward and trying to clarify one of the most confusing parts in technical specification which is Display. For a user this is the most important part and main input/output device. There are lots of factors to consider before you buy as mentioned below.

Display Size

Larger displays give you more space, but at the same time it increases the phone size as well. Decision here is pretty simple. If you need a smaller phone go for small display and if you need large display you have to tolerate the large phone.

Display size of Smartphone generally within the range 3.5” to 5.3”.

Display Resolution

This is the number of pixels placed in the display area. This is normally mentioned in the technical specification as width and height.

EX: 1280 x 800 px

Larger resolution levels would give you more actual space to work. In addition it let you view HD multimedia content as well.

Size – Resolution Sweet Point

This is a tricky point with displays.

• Physically large displays make the phone larger.
• Though the display is large, if it’s having lesser resolution then no point because you have lesser actual working space.
• If the screen is too small, no point of having higher resolution why all the items in it will be tiny.

How to find the sweet spot in Display size and resolution? There you can take a look at the ppi (Pixel per inch), in other words pixel density. Displays with high pixel density will render sharp pictures

ppi Calculation

ppi = {[(display width in pixel)^2 + (display height in pixel)^2] ^ ½} / Display Size in inches

Don’t worry, you won’t have to solve this puzzle. Most of the Smartphone manufactures mention ppi for their displays.

All you have to do is select a Smartphone with desired physical display size and look for ppi value. If it’s greater than 220ppi it would be more than enough for any general work. If your budget allows, go for highest possible ppi value and that kind of display would be super sharp.

Apples iPhone 4S is having 330 ppi display called Retina display. This marketing jargon says that in that kind of pixel density level human eye can’t distinguish pixels in the display.

Display Technology

There are several Display technologies and they will contribute to the quality of display in many ways especially for contrast, brightness, color accuracy and power consumption. Here I have listed them in order and last one is the modern and advanced one.

• LCD: the basic version of thin displays and most of the computer monitors uses this. Less contrast, brightness, color accuracy and power consumption.
• LCD IPS: Slightly upgraded version of LCD and having great viewing angle and color accuracy than conventional LCD.
• LED: Better than LCD when it comes to power consumption.
• AMOLED: The best disply technology. High contrast, brightness, color accuracy and even power consumption. These displays are capable of displaying true black color and having higher contsrat ratio. The best Smartphone in 2011, Samsung Galaxy S II came with AMOLED display.

The most common type today is LCD IPS. Apple’s iPhone 4S comes with this type of display. If you have bigger budget and higher multimedia requirement go for Smartphone with AMOLED display.

Touch Sensitivity and Protection

When you are buying any Smartphone make sure you buy one with scratch resistant font glass. In a technical specification it will mentioned as Oleophobic Coating. If you need more protection go for a Smartphone with Corning Gorilla Glass with is resistant to even serious scratches.

Almost all of the Smartphone today are using capacitive touch screens with multi touch.  Some manufactures says that its 10 fingers multi touch. Your Smartphone display should at least sensitive to 2 different touches.

Wrapping Up

Here I clarify the marketing jargons in Smartphone displays and what they exactly do. Previously I discussed about Processor and Storage Options. Now you have pretty much clear idea about selecting optimum Smartphone for your requirement.

In the next articles I will be talking about Connectivity, Operating System and Batter Life.

If you are a Windows user the main problem you will face with removable storage and internet is Viruses. There are millions of viruses out there and thousands of new viruses coming out every day. Even if you are a Mac or Linux user still you are not 100% safe. There are lots of viruses that attack those OS as well.

Now you might stand up and say “Hey! I have a virus guard installed”. Yeah, that’s good. But does it solve the problem completely? Most of the virus guards come with a price tag and free versions have not-so-good virus signature database. Sometimes one virus guard is detecting a suspicious file as a virus while the other says it’s safe. If you are going online you will have to face this frequently.

However, still there is a no concrete solution the above problems. But there are some good solutions out there. VirusTotal is a free online virus scanning application while is letting you scan files as well as web URLs. The best part is, VirusTotal checks your file or URL using many Anti-virus services and their virus databases.

How to Use VirusTotal?

Web Interface

• Identify suspicious file or web URL.
• If it’s a file upload it to VirusTotal using up-loader in Main page.

• If is a web page change the preference to “Scan a URL” using link below the scan button. This work both ways.
• Then click Scan.
• Once you click scan it will take you to Scanning details page. There you can see VirusTotal is checking your file or URL using many services.
• If you take a closer look in to the list of services you will notice many of the popular Anti-virus Programs also there such as Avast, AVG, BitDefender, Kaspersky, McAfee, NOD32, and Symantec. Using VirusTotal is like using all those Anti-virus applications at the same time.

Desktop Client

Uploading files through a web interface is not that good way to handle viruses and suspicious files. Therefore VirusTotal has released a desktop client which you can directly upload already running applications to VirusTotal and scan them.

This will give you an extra advantage which is you can scan already running processes and their related files using VirusTotal.

• Download VirusTotal desktop application.
• Install it and it will take only few clicks.
• Open the application from the desktop shortcut. It will give you below window.

• There you can see a list of processes which are already running on your computer.
• You can select a process and check the file for viruses.
• You can always upload any file for scanning using the button Select file(s) and upload.
• Same as in web interface this accept web URL as well.

Public API

If you are a programmer and your program need an online anti-virus solution VirusTotal is there for you. From here you can read the VirusTotal API documentation and start your experiment.

Pros and Cons

The most interesting part I see in VirusTotal is that it’s checking our files and URLs against many virus databases from many Anti-virus services. Because of that there is a lesser probability to have false negatives. Providing the desktop client and public API, they have opened the doors for us to use this service without going to their web site. All these come for free.

However, VirusTotal can’t perform entire anti-virus operations same as locally installed anti-virus application. There is no way for us to have Automatic protection like feature with this. In order to scan file or URL we have to manually submit it to the service. Even after detecting as a virus, only thing you can do is delete the file manually, not clean it and reuse. And there is an upload file limit which is 32MB.

Wrap Up

VirusTotal is thinking out of the box in anti-virus applications. They offer it all for free yet integrating many of paid services having the objective of providing reliable service. If you are a techy person, this will be a good solution for you. Whenever you notice something suspicious you can check it for virus using web interface or desktop application. If you are a non-techy person, better to stick to installed automated anti-virus applications.

Finally, I don’t recommend you to use this as your primary anti-virus application since there is no automated files and URL scanning. You can use VirusTotal if you face a difficult situation with your anti-virus application.
