我们总结了“捕获规则”的方法来规划查询在一个面向规则的数据库管理系统。从用于将逻辑规则应用于数据的策略中进行选择可以被视为查询优化的高级形式。捕获规则提供了一个框架，系统可以在其中做出此类决策。他们还协助发展理论的最佳策略的逻辑处理。本文调查了一些已知的捕获规则，并建议如何将它们整合到一个系统中，提供“知识处理”与数据库管理。
We summarize the “capture rule” approach to planning queries in a rule-oriented database management system. Selecting from among strategies for the application of logical rules to data may be viewed as an advanced form of query optimization. Capture rules provide a framework within which a system can make such decisions. They also assist in the development of a theory of optimal strategies for logic processing. This paper surveys some of the known capture rules and suggests how they can be fit together into a system that provides “knowledge processing” with database management.
