In enterprise projects, the need for such state encapsulation grows as the number of other modules that can use your class grows. Finally, dependencies between modules (that is, classes) are reduced by forcing dependencies to be created through interfaces as opposed to allowing dependencies to be created on state and functions that are to be encapsulated. Changes in a class's implementation can thus be made separate from changes to its interface. The tendency for dependencies being formed on your software will grow as the number of software modules that are added to your enterprise software project grows.
We will describe class diagrams in the next section for modeling class relations in a system, as well as for modeling conceptual designs. Conceptual design models that describe the behavior of a proposed design can also utilize the scenario diagrams that are described in the next section. Detailed Design The model packages handed to the designer/developer should correspond to individual software packages. This enables designers and developers to focus on a cohesive component of the system to be developed.
Class Packages: Packages to which classes belong are optionally indicated beneath the class name, such as (from PackageName). • Packages: Packages are shown as a rectangle with a small box in the upper-left corner and have a package name displayed, such as PackageName. • Class Attributes: One or more attributes may be optionally shown below the class name and package name. Some diagrams may choose to display only a select set of attributes. • Class Operations: - 27 - Building Java Enterprise Systems with J2EE One or more operations may optionally be shown below the attributes in a class.
