In a relational database environment related Data Items will be spread across multiple physical tables. By defining the Relationships between tables here you eliminate the need for the person designing reports to understand these Relationships. The designer simply selects fields. Foxfire! knows how to connect the tables to retrieve the requested Data Items.
Join Tree for Preference: Displays a tree view of the defined Relationships for the current Report Set.
Find: Opens the Relationship Finder, a graphical display of the files to allow you to visually define Relationships between files. This tool should only be used for defining new Relationships, it does not provide an effective view of existing Relationships.
