PiggyBank UML Models details |
In accordance with the Rational Unified Process (RUP), the PiggyBank sample UML model is divided into three models that each describe a different aspect of the system: the use case model, analysis model, and design model.
Use case modelThe use case model describes the interactions between users and the system. In addition to the requirements documentation, the use case model contains use case diagrams and activity diagrams that graphically represent the requirements of the system.Analysis modelThe analysis model documents the result of the analysis phase. The analysis model follows the RUP to identify objects that interact with users (boundaries), objects that are persistent within the system (entities), and objects that coordinate the realization of each use case (controllers).Design modelThe design model applies a structured architecture to the analysis model. The design model describes the implementation of the analysis entities of the system, which are implemented as Enterprise JavaBeans (EJBs).These EJBs were implemented using the following best practices:
