Diagrams

Most business systems perform tasks similar to the following:

• Storing information in a database
• Displaying or capturing that information from a screen or a window
• Manipulating the information in some way in between the time it is captured from the screen or window and the time it is stored in the database

CA Gen has more than 30 diagrams; three are directly related to the database design, the window design, and the programming logic. They are:

• The Data Model Diagram (often referred to as the Entity Relationship Diagram)
• The Navigation Diagram
• The Action Diagram

The other diagrams are used to assist with gathering requirements, model confirmation, or with the deployment of the generated applications.

CA Gen diagrams are integrated. You cannot add A to B giving C in an Action Diagram unless A, B, and C were first described in the Data Model Diagram. Technically, it is not so much that the diagrams are integrated, but rather that the objects created by one diagram can be reused or referenced in another diagram. It is the reuse of the modeling objects that brings about this integration.

The Toolset also has a number of Wizards, Patterns, and Templates available to assist with the creation of many of these diagrams.
