Why Web Applications

A web application is basically a software program that runs on the web server. Desktop applications are launched by the operating system, while web applications must be accessed by a web browser. Web applications are far better than desktop applications, as they run inside a web browser and developers don’t require developing web applications for several platforms. For example, a web application that runs in Chrome will be suitable for both OS X and Windows. Developers don’t have to dole out software updates to users when the web application is updated. When they update the application on the server, all users get access to the latest version.

Web Application a User Prospective

From a user perspective, a web application may give a more consistent user interface across different platforms as the appearance is reliant on the browser instead of the operating system. Moreover, the data you enter into the web is saved and processed automatically. This system allows you to go through your data from different devices, instead of transferring files between multiple systems.

How does a Web Application work?

Web apps are mostly coded in browser supported language, for example, HTML and JavaScript because these languages depend on the browser to make the program efficient. Some of these apps are vibrant and need server-side processing. Other apps are entirely static and don’t need processing on the server. The web app requires a web server to deal with the requests from the user, an application server to execute tasks required, and occasionally, a database to save the information. Application server technology varies from ASP, ColdFusion, and ASP.NET, to JSP and PHP.

Future of Web Applications

Some web apps are based on a client-server style where the user enters information while the server retrieves and stores information. Internet mail is a good example of that, where companies like MSN and Yahoo offer web-based email clients. The new push for web apps is crossing the line into those apps that don’t usually require a server to save the information. For example, a word processor doesn’t need a server and collects information on your computer.Web apps can offer the same functionality and get the advantage of working across different platforms.

If you observe the latest Yahoo Mail or Gmail users, you can see how sophisticated Web Apps have become in the past few years. This sophistication is mostly caused by AJAX, which is a programming model for making more responsive web apps. Microsoft Office Live, WebEx WebOffice, and GoogleApps are examples of the latest generation of Web Applications.
