Definition of targets for a relation. Links a relation definition (RelDef) to source and target tables. In general, a relation can be created between any pair of tables. This table is used for specifying which table pairs a particular relation can be used for. A relation definition should have at least one row in this table, and can have more. Note; The 5.0 Maintenance and GUI only support contact and person as valid values for the source_table and destination_table fields, in any combination. Other relations will not be shown, and relation definitions pointing to other tables will not be editable from the Maintenance GUI; however, nothing will crash.
