Ordering and selecting production rules for constraint maintenance: complexity and heuristic solution

Presents a technique for analyzing the run-time behavior of integrity constraint repair actions, i.e. active database rules that are specifically designed to correct violations of database integrity. When constraints become violated due to an incorrect user transaction, rule computation is started t...
