MODELS

• The modeling of the classes used in the application needs to be seen in the same light as that of the database. Without the correct control over what a class can and can not do, how the class interacts with other classes, the development soon gets out of control.
• To achieve a scalable structure that will provide multiple deployment options over the customer base, with the maximum reuse of code, requires a fairly complex package and class structure, this would not be possible in the long term without the capabilities of the high-end tool.
• In the design process visualization of the structure is important in the development of a flexible solution, without been able to see the complete and accurate structure changes are prone to cause problems by closing avenues of expansion.
• The tool of choice is currently Rational Rose. This allows for visual representation of the current development process with the ability to generate the java skeleton stubs for and classes and there methods. As Rational Rose is J2EE aware the potentially complex interfaces for the EJB’s can be modeled and generated from within the Rational Rose Environment saving the developers of creating the interfaces manually.
• Often when generating code from a modeling tool the original code is removed but with Rational Rose the existing code is left unchanged.
