Relationships in domain modeling class diagrams

You can use several relationships to define the structure between Java classes or interfaces or between enterprise beans:

• Association relationships imply that instances of one class connect to instances of another class.
• Dependency relationships imply that a change to one class might affect another class.
• Extends relationships imply that one class is a specialization of another class.
• Implements relationships imply that one class provides a specification and the other class implements the specification.

You can also use note attachment relationships to provide additional information about diagram elements.
