Models in OptimalJ

To develop an OptimalJ application, you use the following models (and submodels):

• Domain model—captures functionality in platform-independent models. The domain model defines the business without any specific application detail and consists of:
  • Class model—specifies the system classes and is graphically represented using class diagrams.
  • Service model—captures behavioral information.
• Application model—describes functionality in the following design models, which are independent of specific code, but are based on a certain technology or application framework, and therefore are PSMs. The application model consists of:
  • DBMS model—the persistency model
  • EJB model—the business logic model
  • Web model—the presentation model

  In OptimalJ, the design models are generated from the domain model.

• Integration model—provides interfaces to legacy and external applications.
  • Connector model—the integration model is subdivided into connector model packages in which you can import and define CICS/COBOL programs/copybooks, CORBA IDLs, and Web services WSDL. It can also be used to define a Web service provided by the application.
• Code model—provides an implementation of the system described by the models. The code model contains the source code (Java language).
