A file represents an entity within your model; for example, Order. It is referred to as an object in a CA 2E data model.
All of your entity objects must be defined to CA 2E by a file name and file type. For each of the objects you define, CA 2E creates a file. A file can be linked either to another file or to a field through a CA 2E relation. The file or field to which it connects is called a referenced object. Referenced objects must also be defined to as either CA 2E a file or field.
A CA 2E file is defined by several different CA 2E relations. Each database (REF and CPT) file must have at least one key relation. The relations are automatically resolved by CA 2E to determine which fields are to be placed on a file.
