Enforcing User-Defined Constraints during the Run-Time in OODB

: In this paper a run-time model is proposed. The run-time model enforces integrity constraints for attributes that are derived from composition and inheritance hierarchies. The run-time model is designed for enforcing the logical integrity constraints in object-oriented databases during the run-time. A new technique called detection method is designed to check the object meta data to detect and catch the object-oriented databases violation before it occurs. Furthermore, we have implemented the RTM and supported set of definitions that are for checking attribute values validity, object-oriented databases consistency, and also a method for verifying attribute values when inserting, deleting, and updating objects.
