When not using FK constraints, data may be modified or lost (deleted) without proper cleanup of related records leading to "orphaned" records without relationships (or related ids that do not correspond to existing records). The disk space for these orphaned records and the time to run a relational integrity checks across tables (removing orphans), is of minor concern and effort, comparative to a troublesome database entry with FK constraints. |
