Overview of Functional and Configuration Model in analysis for WebApps

There are two processing elements of web application. The functional model addresses the above two elements of web application:
- user observable functionality delivered by web applications to end-users.
- operations within analysis classes that implement behavior within class.

User observable functionality encompasses processing functions initiated directly by user. These functions are implemented using operations within analysis classes but from end-user point of view, the function is the visible outcome.

The operations within analysis class manipulate the attributes of the class involved as class collaborate with one another to accomplish required behavior.

The web application must be thoroughly tested within every browser configuration that is specified as part of configuration model.
In some cases, configuration model is not more than a list of server and client side attributes. For complex web applications, configuration complexities have an impact on analysis and design.
Client side software provides the infrastructure that enables access to the web application from user;s location.
On server side, appropriate interfaces, communication protocols and related information should be specified if web application has to access large database or inter-operates with other applications.
