CA 2E Basic Relations

CA 2E provides four basic relation types to describe data relationships: Owned by, Refers to, Known by, and Has.

A relationship expresses an association between two files, or between a file and a field. It constitutes the fundamental links in a CA 2E data model. Such links enable you to explicitly assert the meaning of the connections within your data. A file's list of relationships will be automatically resolved into the fields needed to implement that file.
