The second milestone was the claim that Model 2 provided an MVC architecture for web-based software. [3] Govind believed that because "Model 2" architecture separated the logic out of the JSP and placed it in a servlet, the two pieces could be seen as the "View" and the "Controller" (respectively) in an MVC architecture.
In the design of Java Web applications, there are two commonly used design models, referred to as Model 1 and Model 2. [1]A simplified diagram of a Model 1 implementation. In Model 1, a request is made to a JSP or servlet and then that JSP or servlet handles all responsibilities for the request, including processing the request, validating data, handling the business logic, and generating a ...

A container represents an application or a data store; Component diagrams (level 3): decompose containers into interrelated components, and relate the components to other containers or other systems; Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code.

A deployment diagram [1] "specifies constructs that can be used to define the execution architecture of systems and the assignment of software artifacts to system elements." [1] To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts ...
