Final answer:
When a relate added before a join is removed, the combine data view provided by the relate is lost and the tables revert to their separate states. The relationships established by the relate no longer exist in the join context. Removal of the join eradicates the relate's effects unless the join is re-created.
Step-by-step explanation:
When a relate that was added before a join is removed, the relationships established by the relate are no longer existing in the join context. If the relate had been used to combine data from separate tables, the removal of the join will mean that this combined view will no longer be available, and each table will revert to its original, separate state. In a database management system, relates and joins are temporary unless materialized in some way; thus, when a join is removed, the relate's effects are also no longer present, and queries run subsequent to the removal will not include the related data unless the join is explicitly re-created.
