摘　　要：针对现有本体存储模式存在的无法推理及操作不便等缺陷,本文提出一种新的OWL(Web Ontology Language)文件向关系数据库映射及存储的模式。该模式将本体文件数据提取至由本体ER图(Entity Relationship Diagram)设计的底层数据库中,同时在提取过程中自动获取隐含语义数据,再将底层数据库中的数据映射为便于用户操作的数据库。实验结果表明,该模式既保留了本体文件的隐含语义,又提高了查询效率,同时极大地方便了普通用户对本体数据的操作。By analyzing the shortcomings of existing ontology storage schemas, a new schema of storing ontology files in relational databases is proposed. The schema can obtain the implied semantic data automatically while extracting data from ontology files to the underlying database which is designed from the ER（ Entity Relationship）diagram of ontology, and it then maps the data in the underlying database into a new database which is convenient for users＇ operation. Experimental results show that the schema not only retains the implied semantic of ontology files, but also improves the efficiency of the data querying, what＇s more, it facilitates the users＇ operation for the ontology data greatly.
