Creating object model diagrams

Object model diagrams specify the structure and static relationships of the classes in the system. IBM® Rational® Rhapsody® object model diagrams are both class diagrams and object diagrams, as specified in the UML. They show the classes, objects, interfaces, and attributes in the system and the static relationships that exist between them. Note that an object model diagram is specified for the object structure, while a class diagram is specified for the class structure.

More than simply being a graphical representation of the system structure, object model diagrams are constructive. The Rational Rhapsody code generator directly translates the elements and relationships modeled in object model diagrams into source code in a number of high-level languages.

Note: If you have a large diagram and you want to view a specific area of the diagram while you keep available a view of the diagram in its entirety, you can use the Bird's Eye window. The Bird's Eye window (also known as the diagram navigator) provides a high-level view of the diagram that is currently displayed in the drawing area. To open this window, select View > Bird's Eye. To enlarge or shrink the visible area of the diagram in the drawing area, drag an edge or corner of the rectangular viewing port on the Bird's Eye window to enlarge or shrink the viewing port. Enlarging the viewing port has the same effect as zooming out in the drawing area. Shrinking the viewing port has the same effect as zooming in the drawing area.
