一种在关系型数据库中存储OWL对象的方法

An Approach to Store OWL Object in Relational Database

本为在调查了几种在关系型数据库中存储OWL和RDF对象的方法的基础上,分析了每种方法的不足,提出了一种新的方法,即把每类对象和属性的实例存储在数据库单独的表中,使用数据库中的视图来表示对象之间的关系。我们也实现了一个Java程序来实现描述逻辑推理器的功能,把用户输入的一阶谓词逻辑查询转换成为关系型数据库的SQL语句。实验证明,本方法适用于中等数量的OWL对象的存储。

In this paper, on the base of investigating several methods to store OWL or RDF object in Relational Database and the tradeoff of each alternative, we suggest a new approach through storing the instances of each classes and properties in distinct tables and using views to represent the entailment of the OWL object. We also implement a Java application to finish the query of the ontology object as description logic reasoner through translating the first-order logic query from the user into SQL statements of the RDBMS. This approach provides good result for extensional queries over moderate size of OWL object and can provide adequate usage for oersonal or small business.
