TREATMENT OF ENGINEERING DESIGN CONSTRAINTS IN A RELATIONAL DATA BASE

In this paper, a mechanism for representing and processing design constraints is presented. The mechanism can be used for checking constraints, that is, determining whether they are satisfied or violated, as well as for assigning attribute values such that the applicable constraints are thereby satisfied. Furthermore, thee mechanism provides flexibility in sequencing the enforcement of constraints, by allowing new constraints to be applied to a preexisting state of thee data base as well as to all subsequent transactions on thee data base. In both these respects, the mechanism proposed appears to have applications beyond engineering design. The paper demonstrates the implementation of the constraint management mechanism using the Relational Information Management (RIM) system, a commercially available data base management system (DBMS).
