I have many different tables that I want to keep track of. So, I thought of a master table with those table names in it. But, to maintain this (suppose a table changes its name, gets dropped) I want to have some kind of referential integrity - the way foreign keys and constraints do. What could I use that would disallow inserting a name into the master table unless another table by that name already exists? And what could ensure that a table would not be renamed or dropped unless the master table is changed?
