将一阶模态语言转换为关系代数

Translating a first-order modal language to relational algebra

Yeb Havinga

摘要:

这篇文章是关于关系数据库中的Kripke结构,并使用模态语言进行查询。首先介绍所使用的模态语言,然后是数据库和关系代数的定义。基于这些定义,提出了两件事:从模态结构的组件到关系数据库模式和实例的映射,以及从模态语言中的查询到关系代数查询的转换。

英文摘要:

This paper is about Kripke structures that are inside a relational database and queried with a modal language. At first the modal language that is used is introduced, followed by a definition of the database and relational algebra. Based on these definitions two things are presented: a mapping from components of the modal structure to a relational database schema and instance, and a translation from queries in the modal language to relational algebra queries.
