We use the ontolog y test frame of the educatio n r ealm to test the storag e schema finally. T he ex periments show that the new ontolog y sto rag e schema of the r elational database in this tex t has higher searching efficiency and friendly ex pansion functions. It has more super io r functions in each aspect than the perpendicular sto rage schema being used ex tensively now . It is also practical in saving lar ge-scale ontolog y. 关键词: 网络本体语言; 资源描述框架; 本体; 存储 Key words: OWL; RDF; ontolog y; s
