RDF在关系数据库中的存储研究

Research on Storage of RDF in Relational Database

资源描述框架(RDF)是Web资源信息的规范性描述语言,如何存储RDF数据成为当前重要的研究问题.通过深入分析RDF数据的特点,提出了一种新的基于关系数据库的RDF存储模式,给出了RDF在关系数据库中的存储规则,提供了相应的存储实例.基于提出的存储方法,实现了相应的自动存储原型系统,通过实验进一步验证存储方法和原型系统的可行性,并与已有存储模式进行了理论对比分析.

Resource description framework（ RDF） is a normative language to describe the Web resource information. Howto store RDF data is becoming an important research issue. By analyzing the characteristics of RDF data,a storage model of RDF was proposed based on relational databases. The storage rules and a storage example were given. On the basis of the proposed storage approach,a prototype storage tool was implemented,and the experiments shown that the approach and the tool are feasible. Also,the theory comparative analyses with the existing storage modules were done.
