摘要

我们提出了一种关系模型的集合论解释，它允许语义方法来查询回答。我们证明了通过集合包容从数据库中的元组中演绎出新的元组是可能的，并给出了演绎式查询应答的算法。

Incorporating functional dependencies in deductive query answering

We present a set-theoretic interpretation of the relational model which allows a semantic approach to query answering. We show that deduction of new tuples from those in the database is possible through set-containment and we give an algorithm for deductive query-answering.
