摘要

通常对数据、约束、更新和检查数据库完整性的方法施加的各种要求可以被视为不灵活的约束。我们表明，这些限制可以明显放宽，甚至完全放弃，而不会丧失任何主要优势。相反，通过放松或放弃几个已建立的完整性检查先决条件，可以获得相当大的灵活性。

Getting Rid of Straitjackets for Flexible Integrity Checking

Various requirements that usually are imposed on data, constraints, updates and methods for checking the integrity of databases can be perceived as inflexible straitjackets. We show that such restrictions can be notably relaxed or even completely abandoned without forfeiting any major advantage. On the contrary, a significant amount of flexibility is gained by relaxing or abandoning several established prerequisites for integrity checking.
