Web application development services have been launched  for making applications usage easier and safer for the consumer. There are many advantages of going online to utilize applications as opposed to using desktop applications are rising  progressively. With many web applications development companies’ cropping up and providing best services, the assortment and miscellany of web applications is also on the rise.

A web application alleviates the developer of the responsibility of building a client for a specific type of computer or a precise operating system. The term client is used in client server environment to submit to the program and users are using to run the application. The client server environment is one in which various computers share detail such as entering information into a database. Since the client runs it in a web browser, the user could be using Windows XP or Windows Vista or any operating system. They can also be using Internet Explorer and Firefox, though some applications need a definite web browser. Web applications frequently use an amalgamation of server-side script - ASP, PHP, etc and client-side script - HTML, JavaScript, etc to build up the application. The client-side script covenants with the presentation of the detail whereas the server-side script deals with storing and retrieving the information.

Some of the advantages of web applications and as a result the web application development services that bring them to us are as follows:

• Web applications don't need to be installed and consequently saving you sufficient space on your hard drive. During the time to upgrade your application, no need to buy nor install the same. The web applications provider will take care of upgrade.
• Shopping around for an appropriate web application development service is easier as you by now have access to numerous different options.
• Your data is safer against the occurrences of system failure; your data is well protected in the online application service.
• Location is not going to bar anyone. User can easily log to web application of choice from anywhere in the world that has internet connection.
• Access will be established every day of the week so work requires not stay in the office or office hours.
• Web application providers can assess log INS and monitor the usage of the application.

Future of web applications is bright. The new Gmail and Yahoomail clients are using classy web applications in recent few years. Much of that is because of AJAX, which is a programming model for generating more approachable web applications. Google Apps, Microsoft Office Live, and WebEx WebOffice are examples of the latest generation of web applications.

Web applications have become very much popular these days as they are the most convenient to use. Ever since the advent of internet, our life and the way we do things has change drastically and with web applications, it has made our job even easier. Wikipedia defines web application as “In software engineering, a web application is an application that is accessed via a web browser over a network such as the Internet or an intranet. The term may also mean a computer software application that is hosted in a browser-controlled environment (e.g. a Java applet)”. 

However, the user of web application would differ slightly from this definition and say that web application is like an ever ready steward to serve the required things on the platter. No wonder that web applications have got popular these days as you don’t need to install any software in your computer to run particular programs. After all, the usage of web applications has saved the web users from plenty of time consuming and costly tasks of maintaining and updating client server workstation and so on.

The web application development has basically enhanced the productivity by creating dynamically a series of web pages in a standard format of HTML/XHTML. These formats are generally compatible with all the popular web browsers. The most popular web applications these days perform several kinds of functions such as webmail, online retail sales, online auctions, discussion boards, weblogs, MMORPGs and much more. The web applications can do that for you easily over the web as they are generally ubiquitous with all kinds of browser such as Firefox, IE, and Safari and so on.

Web application has made it possible to play audio, draw on screen, access to the keyboard and mouse through JavaScript, Flash and several other technologies. An expert web application developer can coordinate client side scripting with the server side technologies including PHP, ASP, AJAX and so on.

Search engines are pretty much effective in fetching relevant traffic to the websites and since for most of the websites, more than 50% of traffic is originated through search engines. Therefore, the prevalent challenge these days is to fully index the flash websites that are made on the RIA (Rich Internet Applications) platforms. Several clients prefer to make their websites on various technologies and platforms that make use of RIA such as Ajax, Curl, JavaFX, Microsoft Silverlight, Adobe Flash, and Flex. Adobe partnered with Google and Yahoo regarding this concern of making the Rich Internet Applications accessible to the search engines just as the other web applications.

A successful solution to this problem is Search Optimized Flash Architecture popularly known as SOFA. This solution has multiple benefits such as:
•    It makes the flash website searchable.
•    It provides accessible alternative web site.
•    It provides links to content deep within the flash website.
•    It also allows the user to use browser buttons to move forward and backward within the flash website.

The two key features for improvement of the Search Engine Optimization efforts are indexing and relevance. Over here, the indexing refers to directing the crawlers to what content and where it is located for crawling. Relevance refers to the deep linkable content that is interesting and catering to the user’s need so that they link to it. SOFA is a unique technique that can serve for both these SEO efforts within a flash website.

How Does The SOFA Technique Work:

It is a revolutionary technique for the Flash Rich Internet Application development platform and focuses on making the content of the flash website accessible and at the same time making it capable of indexing it too. The technique has now made it possible for the flash file (SWF) to be indexed by the search engine.

Commonly, the flash file is placed on an HTML page which in the recent times is converted into well developed into the XHTML as it is the well-formed XML file. This kind of file enables the developers to use the externalized content. What SOFA does is that it uses this XHTML as a flash content source and to locate the flash placement as well. Since the search engines can easily crawl through the XHTML, it can easily index the content of the flash website too. Hence, the first SEO effort of indexing the flash website is solved by the SOFA technique.

Second SEO effort is of linking. Generally, whenever a viewer of the website finds content in a search engine and links it, a check is prompted automatically to check if that particular user/viewer has flash or not. If the user does not have flash then the XHTML content is stylized with the usage of CSS so that he non-flash version of the page is accessible to the user. However, this is true only for a single RIA page. Therefore, when there are multiple deep pages and large quantities of content the above method just sounds too impractical. For this, the developer makes multiple XHTML pages with an index page following a navigation list which is inclusive on anchor links too. So the search engine crawlers follow the linked content and hence, the second major SEO effort is also actualized.

This the way a flash website can be turned into SEO friendly. Thus, this technique ensures the accessibility of your flash website by both the users and the search engines.

Each and every day there is something new or the other in the world of technology, when Silverlight was introduced by Microsoft, it came with a boom in the market. Silverlight is a browser plug-in that can be programmed for developing rich internet applications. But why has Sliverlight become such a popular platform for all the developers? Here are certain unique features of Silverlight that might just help us to realize this.

• First and foremost benefit of Silverlight is due to the .NET libraries that are amazingly packed up by Microsoft. Unlike other external libraries in other environments, .NET libraries have JSON parsing is in-built and works fantastically for Silverlight.

• It is a cross browser, cross platform, and cross device plug-in by Microsoft that can enable companies to design, develop and deliver some of the best applications on the web.

• The Visual Studio is the best IDE for working on the Microsoft technologies. In fact, it does better work than Xcode and TextMate do on MacOS.

• In Silverlight development environment, the user can supersede the entire visual tree for any control and thereby save huge time.

• It also has multi programming language support like Visual Basic, C#, Python and Ruby.

• It has a JavaScript extension as well.

• The content and the media are well protected by it.

• It can integrate HTML DOM.

• Silverlight is available for free in all the supported browsers.

• It also has the ability to update itself involuntarily.

Thus, Silverlight has all the qualities that can easily challenge Flash, Flex, and AJAX but it still has room for improvement in it. The developers so far can integrate Silverlight with the existing applications, develop audio visual website with animation and graphics and build several RIA with the help of Silverlight development platform.

Adobe Flex has acquired worldwide acclaim as one of the best platform for building Rich Internet Applications along with Adobe Flash.
