Table Requirements

In order to be a crr a table must:

• Have one or more primary key columns
• Have no enforced foreign key constraints. Unenforced foreign keys are fine.
• Have no other unique indices besides the primary key(s)
• Columns are either nullable or have a default value.

Tables that are not crrs have no requirements.
