The rational storage of ontology is the premise of the shareable use of ontology.Under current ontology storage schema,some problems such as difficult maintenance,low query and inference speed may appear after ontology storing in relational databas.Firstly current ontology storage methods are analyzed.Secondly ontology storage schema is designed according to ontology characteristic.The principle of designing ontology storage schema is given and a new storage schema is proposed based on the principle.In this schema,according to the characteristics of ontology description language,frequently queried information is stored in multiple tables,which makes the schema understandable and stable.Furthermore the schema can increase the query efficiency by reducing the cost of table join.
