Features Highlight

Controls

The display is relatively large than a normal personal or a music phone. It makes the content and enhances the image and video display features. In addition it is much developed with the 262 color scheme to deliver much colorful content. Keypad consists of two parts. The controller keypad is a much strengthen and attractive one. The number pad is relatively soft, but can look fine with the background light. It is much similar to a Nokia keypad. Motion Sensitivity is one of the well highlighted and attractive features available on the Sony Ericsson C905. It let the user feel much comfortable by reducing the number of times he has to press the buttons for switching between landscape and portrait. Users can enjoy the games without pressing the keypad at all. The ‘Need for Speed Pro Street’ is supported by the motion sensor option. 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 phone might have been very much perfect if there was a front camera. Therefore the 3G calls are also need to get the support of the main camera. It is said that this phone is the phone with most advanced zooming capabilities. It supports up to 16X digital zoom while giving QVGA video recording with 30 frames per second. The lens protection is also enhanced with the mechanical lens cover that has a slider and push back cover in it.

Walkman Headset And The Music Player

The Sony Ericsson C905 Walkman Media Player 3.0 is attractive and optimized than the any previous editions of the Sony Ericsson phones and it can add playlists of the Windows Media Player that runs on the computer from Bluetooth. The flash interface looks gorgeous and the Stereo Widening option gives a better quality audio output. There are number of equalizing techniques available. Base, Mega Base, Full Treble and voice are them. Super Base is the best quality equalizer among them. Other than the Walkman (‘W’ series) phones are provided with a normal stereo headset. 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.

Specification and Features

Its operating system is similar to iPhone’s operating system and has custom designed A4, Apple 1GHz Processor. It has 1024 x 768 resolutions, 9.7 inch LED touch screen, 1.5 pounds weight, 0.5 inch thin and it has around 10 hours of battery life as well. iPad has the fasters built-in 802.11n Wi-Fi connection, Bluetooth 2.1 + EDR and 7.2 Mbps 3G data speed. There are particularly designed games and apps available for iPad and an iWork suite which contains word processing, spreadsheet and presentation software especially for business use also announced. The starting price will be around $499 (16 GB). If you want to use AT&T connectivity, which is Apple recommended, another $130 will be added to the price. Apple’s iBook the virtual bookshop is one of the main features in iPad. You can turn pages with a single tap in the right-hand margin.

In addition, you can have a bunch of photo album in your iPad, and when it’s charging state, you can use it as a digital photo frame. Moreover, its high-resolution screen makes it perfect for watching any kind of video such as HD movies, TV shows and music videos. It has a unique YouTube app where you can easily navigate videos and organize videos. With the iPod application, you can browse, organize and listen to music with the powerful built-in speaker. The iTune store lets you to browse, buy music, TV shows or you can buy or rent movies with thousands of collections or you can sync with your Mac or PC to share the contents through iTune. There are around 140,000 applications available for iPad and you can easily browse, buy and download them from App Store.

The Google powered helps you to navigate with high-resolution satellite images where you can use your current location as well as you can get the directions. To taking notes, iPad has an onscreen keyboard and in landscape view, you can see your list of notes and the current one will shown win a red circle. From the Home Screen, you can have access to everything in your iPad in a tap and you can move apps around the screen in any order you want. Finally, the Spotlight Search allows you to search across iPad and its built-in apps.

Lack Of Functionalities

Even though iPad has the entire above-mentioned feature, it has failed some functionality as well. Due to lack of multitasking that means that you cannot listen to music while editing a photo. It’s a major issue in iPad. It does not have a camera. Even the iPod nano has a camera, so a business product without a web cam or at least a normal cam. So no video chatting, no photo snaps. It does not include a USB port, so file transfer between other devices will be difficult and inconvenient. Users have to depend on a USB adapter. Most of the users never accept this. iPad doesn’t support Flash. Which means you cannot view Flash embedded sites and applications. The main arguments against Flash running on the iPad are that it’s a resource hog and a security risk, but the lack of Flash support is nonetheless a hindrance for users. While the iPad’s display has been praised as crisp and sharp, its screen — LED-backlit with In-Plane Switching (IPS) — has its downsides. The iPad’s screen is not as power efficient as OLED devices, which don’t drain batteries as quickly. Moreover, LED screen tends to be harder on the eyes than the e-ink screens used on eReaders such as the Kindle. Apple has its own App Store for iPad and it has a lot of restriction on apps like no porn, nothing that infringes on the Apple trademark etc. The Free Software Foundation has already criticized the product, saying iPad is bad for freedom.

People have to think is it worth to buy this product for $500? Moreover, user has to depend on the iStore.  We can expect more features and bug fixed updates in future. However, for now its people have to decide do they really want to replace their current device to iPad.

When working on complex operations with a large set of data using a table-based database system, it   needs more resources and time consuming and it is actually an incredible piece of software but it might not be the best tool for every stored procedures. NoSQL is easy to use database system, its performance is fast, and it is a portable without any limitations other than the memory and the processor speed.  It uses key, value pair to store data so, if you want to keep your data in a persistent state and have access to them, then this would be an ideal database system. The object databases are been based on client-centric architecture rather than server-centric architecture and the queries are performed on the client. In addition, without bound to server hardware limitation, the data can be partition and scaled easily. However, if you have to work with around 10 gigabyte of data table that must be update each second from various clients, you cannot rely on the NoSQL since it lacks of performance on very big tables. At the same time some NoSQL databases do not even support a basic feature like automatic partitioning, but they provide reliability features like distribution, replication, snapshot, record-level version history, and MVC. Those are the reasons people like NoSQL most.

It is closely integrated and an extension of the UNIX environment. When using NoSQL, a database is just a regular UNIX ASCII file and you can use, move and maintain it as any other files that you have access. In addition, it does not need a fixed schema or data type, it does not have the ‘JOIN’ query, and ACID (Atomicity, Consistency, Isolation and Durability) properties are not important here. Moreover, queries are relatively simple than relational database system. Moreover, when using the table-based database system, there will be problems regarding the versions, but in this NoSQL database, you do not have to care about which version you are developing and which version the clients have.

There are some well know companies use the NoSQL databases as their storage and retrieval database system. Facebook’s Cassandara, LinkedIn’s Project Voldemort, Google’s BigTable and Amazon’s Dynamo are some of them. Chordless, CouchDB, Db4o, GT.M, Hbase, Hypertable, Memcachedb, Mnesia, MongoDB and Redis are some popular open source NoSQL projects.

Nowadays, the web community is more developed than it was. Therefore, it needs more technology with high performance rather than the traditional way of RDBMS to store and retrieve data. To meet the requirements of many ecommerce applications it needs an object database such as NoSQL where you can work with your own preferred language. If you have problems related to the scalability like reaching the limit of the write capacity of a single database server, amount of data is greater than a single server can hold or your page loading is being slow as well as structure related problems like tables with lots of columns and a little of them are actually used, and have a lot of join queries to deal with or your schema have a large number of many to many join tables you can think about to change to NoSQL.
