Web Application

A computer program or set of programs that are called from a web portal and used to perform a given business function—such as purchase a product. The term may also mean software application that is coded in a browser-supported language (such as Java) and reliant on a common web browser to render the application’s executable over internal networks or over the Internet. These applications can either be purpose-built or purchased from a vendor; they usually link to other legacy or special-purpose background applications that can access multiple databases or perform given functions in the background while the web application continues to interact with the application user.
