Component Model

The Component Model is a flexible tool for constructing and viewing the data model. It offers an alternate view of the Data Model Diagram, Data Model Browser and Data Model List tools. Changes made to the data model in one of these tools are visible in all other tools.

The Component Model allows you to:

• Create any number of diagrams, including overlapping diagrams, to show pieces of the data model based on your needs
• Add, modify and delete entity types, subtypes, operations, relationships, and attributes

Using the Component Model, you select entity types to place on the diagram. It is not necessary to place every entity type. Also, the same entity type can be placed on more than one diagram.

A Component Model diagram is restricted to a particular subject area. When the root subject area, representing the entire model, is selected, any entity type in the model can be placed in the Component Model. When a lower level subject area is selected, only the entity types in the selected subject area can be placed on the diagram.

There is no limit to the number of Component Model Diagrams that can be created for any given subject area.
