Creating/Defining Your Data Model › Defining Your Data Model

Defining Your Data Model

The purpose of this chapter is to define and create files, fields, and relations based on the entities, attributes, and relationships from your conceptual model. The files, fields, conditions, and relations are the CA 2E basic model design objects that must be defined and created before you can build access paths and functions to operate on your model.

See the chapter “Understanding Your Data Model” for more information on files, fields, conditions, and relations.

This task consists of three steps:

1. Defining Files

2. Defining Fields

3. Entering Relations

You can choose to do one step at a time or to combine all three steps by entering CA 2E relation statements first.
