Database survivability under dynamic constraints
The connection between static constraints satisfied by a database and its future evolution under dynamic constraints is investigated using the notions of survivability and survivability-closure. The static constraints considered here are functional dependencies (fd's). The dynamic constraints are restricted to commonly arising analogs of fd's, called ''dynamic'' fd's. The results provide new tools for the design of database schemas containing both static and dynamic constraints.
