摘要

本章探讨了主动规则和完整性约束之间的相互作用。首先，我们按照SQL-1999标准委员会的观点分析静态案例，到目前为止，它代表了最先进的技术。然后，我们考虑动态约束的情况，我们使用时间逻辑形式。最后，我们讨论了该方法的适用性、局限性以及在试图保证动态约束的满足时所发现的部分解。

Integrity Constraints in an Active Database Environment

This chapter surveys the interaction between active rules and integrity constraints. First, we analyze the static case following the SQL-1999 Standard Committee point of view which, up to date, represents the state of the art. Then, we consider the case of dynamic constraints for which we use a temporal logic formalism. finally, we discuss the applicabilty, limitations and partial solutions found when attempting to ensure the satisfaction of dynamic constraints.
