What ia a Web Application?

In software engineering, a web application is an application delivered to users from a web server over a network such as the World Wide Web or an intranet. Web application programming (the adding of dynamic pages) on a web site links to databases and creates interesting interface features. Web programming connects the interface to any applications or databases that reside deeper in the product.

Most web applications have a back-end and a front-end and use the database as a back-end. Back-end and front-end are expressions that describe programs relative to the user.

A front-end program is one that users interact with directly. The front-end is responsible for collecting input from the user, which can be in a variety of forms, and processing it in such a way that it conforms to a specification that the back-end can use.

A back-end program supports the front-end services and tasks not directly controlled by the user. When building a database a programmer sets the "invisible structure" of the information displayed in the front end.

Web applications are popular due to the use of the web browser as a client, sometimes called a thin client. The ability to update and maintain applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity.
