Indexical Constraints

Indexical Constraints. A key issue in Constraint (Logic) Programming system, is the implementation of the underlying Constraint Solvers. A number of features of these solvers must be taken into account: The ease in representing domains and generic constraints;

Integrity Constraints

Integrity Constraints. An important functionality of a DBMS is to enable the specification of integrity constraints and to enforce them. Knowledge of integrity constraints is also useful for query optimization. Examples of constraints: keys, superkeys foreign keys
