By analyzing the OWL Ontology storage medium and storage schema of the relational database, the flaws of various ontology storage modes are pointed out,a new ontology storage schema based on relational database is given. We use the ontology test frame of the education realm to test the storage schema finally. The experiments show that the new ontology storage schema of the relational database in this text has higher searching efficiency and friendly expansion functions. It has more superior functions in each aspect than the perpendicular storage schema being used extensively now. It is also practical in saving large-scale ontology.%本文深入研究了本体的存储介质以及本体在关系数据库中的存储模式,指出当前各种本体存储模式的不足之处,提出了新的基于关系数据库的混合存储模式.用教育领域本体测试框架对所提出的存储模式进行实验验证.实验结果表明,该文所设计的基于关系数据库的存储模式具有结构清楚,查询效率高和扩展性能强的优点.用该文设计的混合存储模式要比目前广泛使用的垂直模式在各方面的性能都更优越,而且也适宜于存储大规模本体.
