Gupta, A. and Sagiv, Y. and Ullman, J. and Widom, J. (1994) Constraint Checking with Partial Information. In: Thirteenth ACM SIGACT-SIGMOD-SIGART Symposium on Principles of Database Systems, May 24-26, 1994, Minneapolis, Minnesota.
Constraints are a valuable tool for managing information across multiple databases, as well as for general purposes of assuring data integrity. However, effcient implementation of constraint checking is diffcult. In this paper we explore techniques for assuring constraint satisfaction without performing a complete evaluation of the constraints. We consider methods that use only constraint definitions, methods that use constraints and updates, and methods that use constraints, updates, and "local" data.
