The Internet, in today’s world is the most popular platform for users when it comes to seeking information about any product or service. As a result, it has also become one of the most sought after platforms by service providers to make themselves visible on. For this purpose, there is a need to develop a website for the organization with all the required applications and equipped with all the necessary components. A web page consists of different components and content which make it a complete page, suitable to be viewed over the Internet. Several aspects are associated that help the website to function and perform well in the World Wide Web. Not just that, a proper web page development procedure also involves constant improvement and evolution of the website and its components or applications in accordance with the emerging trends in the cyber space.

Web engineering is the discipline that helps in the development of web pages appropriately. Web engineers are the experts who take care of the technical aspects of a website. The calculations required to make a website just correct is their forte. Well known website or web application development experts help in making the web pages and web applications reliable, easily usable and of great quality. But, added to that, some specific areas need specialized knowledge. Only expert web engineers who have in depth knowledge of such aspects can handle and deal with them easily. They are specialized in the use of the tools, techniques and methods which are used for successfully developing the right basis and platform for web applications. They help in the entire process of developing web based apps which include designing, development, related calculations and its evolution.

A further categorization will indicate the various disciplines which come under this area of engineering. It includes system analysis, system designing, hypermedia or hypertext engineering, software engineering, study on interaction of human and computers, requirements engineering, indexing and retrieval of information, project management, graphics designing and so on.

Reputable web page development companies implement the use Rich Internet Applications (RIA) for creating the best websites. This provides the users with an excellent experience while navigating through the websites. The information as well as multimedia components can be presented in an attractive and rich interface. Thus, with the best companies, designing and developing the right web page is assured. Their tools, methods and cutting edge technologies bring out the optimum in e-businesses.

The Nokia E5 Combines Full E-Mail Integration With a Series of Multimedia and Social Networking

Nokia clearly know what they are doing when it comes to producing QWERTY smartphones. Previous E series phones like the E72 and E71 have been very popular among business folk; this is mostly down to the e-mail services and online aspects the phones offer. The Nokia E5 is no different; it combines full e-mail integration with a series of multimedia and social network features. There is a full web browser accompanied by high speed internet connections and a digital camera with a multimedia player and FM radio.

The device looks very handsome and very professional; the 2.36 inch screen has 320 x 240 pixels (QVGA) and has been installed horizontally which is ideal for web browsing and messaging. The E5 is available in a range of office friendly colours like White, Grey and Brown, but it also looks quite nice in the Black and Sky Blue variations. The classically designed keyboard is made up of very well sized keys, and they are all neatly lined up beneath the five-way Navi key which is the main navigation tool for the Symbian S60 phone. The Monoblock form factor gives rigidity and reliability to the feel and the smooth casing makes for a comfortable handling experience. As per usual Nokia have stuck to what they and there customers know best and used the Symbian S60 OS on the E5. The interface will be familiar to passionate Nokia fans, and will be easy t get used to for first timers. The main home screen is packed with information which can be customized to suite the user, the information is split into rows with your favourite contacts at the top, your e-mail, internet and social networking in the middle and a line of customizable widgets at the bottom. An in-house QuickOffice application lets users view Microsoft files and e-mail attachments on-screen. The E5 can even be entirely synched to a work or home computer, with access to documents, photos, the calendar and contacts.

Where messaging is concerned, the E5 is well covered. With support for Exchange and other business e-mail accounts this device is capable of receiving real time e-mails from work accounts. Up to 10 accounts can be handled at once with compatible providers including Hotmail, Gmail and Yahoo! Mail. For an alternative, users can also utilise the IM support offered by the E5; the dedicated client is attuned to handle live conversations via the likes of WindowsLive, GoogleTalk and Yahoo! Chat. Ovi offer there free services in the messaging field with Ovi Chat and Ovi Mail. The in-built browser allows users to access all the information and online services they could imagine over a super fast 3G or Wi Fi web connection. The phone can also receive Facebook and Twitter feeds and there is support for full SNS management with the dedicated application. Other Ovi services include there Ovi Maps, which when combined with the in-built A-GPS receiver will help with route planning and access to the Ovi Store and Ovi Music Store, combined they allow access to thousands of apps, themes and tunes to build a collection. Support for a 32GB microSD card is a welcome feature with a 2GB SD card coming as standard. A 5MP digital camera is enough for good quality still images and great video capture; it is accompanied by a LED flash with various settings and image editing tools. The music player will handle your favourite tracks, while the video player is calibrated to handle multiple codec’s. The 3.5mm AV jack can be located on the phones chassis and it will take most headphones.

The Nokia E5 is a professional phone for professional users. The look, the feel and the performance most of all point to the business population more tan anything else. The phone is app heavy and provides an in-depth smartphone experience, and though it lacks a little in the multimedia department, it shines in the online and messaging fields. The Nokia E5 is sensibly priced and very pocket friendly for the right customer.

Advanced Databases: Their Needs and Importance

Advanced Databases are becoming more rampant, advantageous and applicable to real life as developers of these databases strive to make that happen. In this article, I give an overview of several advanced databases and explain why they are important

Here I cite three such kinds of databases:

1. Distributed Databases

A distributed database is a database with one common schema whose parts are physically distributed via a network. For a user, a distributed database appears like a central database i.e. it is invisible to users where each data item is actually located. However, the database management system (DBMS) must periodically synchronize the scattered databases to make sure that they have all consistent data.

Advantages:

  1. Reflects organizational structure: database fragments are located in the departments they relate to.
  2. Local autonomy: a department can control the data about them (as they are the ones familiar with it)
  3. Improved availability: a fault in one database system will affect one fragment instead of the entire database.
  4. Improved performance: data is located near the site of greatest demand; the database systems themselves are parallelized, allowing load on the databases to be balanced among servers. (A high load on one module of the database won’t affect other modules of the database in a distributed database)
  5. Ergonomics: It costs less to create a network of smaller computers with the power of a single large computer.
  6. Modularity: Systems can be modified, added and removed from the distributed database without affecting other modules (systems).

2. Data Warehouses

A data warehouse (DW) is a subject-oriented, integrated, non-volatile and time-variant collection of data in support of management’s decisions. (Inmon’s definition).

Explanation:

  • Subject-oriented: The system focus is not on the applications required by the different departments of a company (e.g. econometrics and finance, medical research and biotechnology, data mining, engineering etc) but on subject areas, those that relate to all departments like customers, products, profits etc. Traditional database systems are developed for the different applications and data warehouses for the subject areas.
  • Integration: Data from various sources is represented in the data warehouse. Different sources often use different conventions in which their data is represented. It must be unified to be represented in a single format in the data warehouse. E.g., Application A uses “m” and “f” to denote gender. Application B uses “1″ and “0″ and application C uses “male” and “female”. One of the conventions can be used for the data warehouse; others can be converted.
  • Non-volatility: Data that have migrated into the DW are not changed or deleted.
  • Time-variance: DW data is stored in a way to allow comparisons of data loaded at different times (e.g. a company’s profits of last year versus the profits of the year before that). DW is like a series of snapshots of the data of its different sources, taken at different times, over a long period of time (typically 5-10 years).

The purpose of most databases is to present current, not historical data. Data in traditional databases is not always associated with a time whereas data in a DW always is.

Advantages:

  1. Because DW is subject-oriented, it deals with subject areas like customers, products and profits relating to all departments of a company but not to different applications relating to different departments.
  2. It converts non-homogeneous data to homogeneous data.
  3. Data do not require to be updated or deleted. It can be stored redundantly.
  4. It can present historical data over a period of 5-10 years. So it can be used for the purpose of analysis of data.

3. Multimedia Databases

Multimedia databases store multimedia such as images, audio and video. The database functionality becomes important when the number of multimedia objects stored is large.

Advantages:

  1. The database supports large objects since multimedia data such as videos can occupy up to a few gigabytes of storage.
  2. Similarity-based retrieval can be utilized in many multimedia database applications. For example, in a database that stores fingerprint images, a query fingerprint is provided, and the fingerprint(s) in the database that are similar to the query finger print are retrieved.
  3. The retrieval of some types of data such as audio and video has the requirement that data delivery must proceed at a guaranteed steady rate. This is a good upside as for example, if audio data are not supplied in time, there will be gaps in the sound. If data are supplied too fast, system buffers may overflow resulting in loss of data.

These are several of the advanced databases that are taking bigger roles in real life, and their abundant merits make them even more an important part of data storage, retrieval and applicability to life next to conventional relational databases.
