Web Application Development
A web application is a computer program that utilizes web browsers and web technology to perform tasks over the Internet.
Millions of businesses use the Internet as a cost-effective communications channel. It lets them exchange information with their target market and make fast, secure transactions. However, effective engagement is only possible when the business is able to capture and store all the necessary data, and have a means of processing this information and presenting the results to the user.
How a web application works
The web application requires a web server to manage requests from the client, an application server to perform the tasks requested, and, sometimes, a database to store the information. Application server technology ranges from ASP.NET, ASP and ColdFusion, to PHP and JSP.
Here’s what a typical web application flow looks like:
User triggers a request to the web server over the Internet, either through a web browser or the application’s user interface
Web server forwards this request to the appropriate web application server
Web application server performs the requested task – such as querying the database or processing the data – then generates the results of the requested data
Web application server sends results to the web server with the requested information or processed data
Web server responds back to the client with the requested information that then appears on the user’s display
