No Foreign Key Relationships?
I was just looking through the tables for my BuddyPress installation and noticed there are no foreign key relationships specified between some tables — wp_bp_groups and wp_bp_groups_members, for example.
Am I correct that there are no integrity constraints? If so, what possible possible justification could there be for that, how can you ensure data integrity, and is there a script or plugin available that will add all the proper integrity constraints?
