Design of OWL Ontology Storage Schema in Relational Database
Yao Hong-yan · Computer Technology and Development · 2007
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 OWL ontology storing in relational database.Firstly current ontology storage methods are analyzed.Secondly ontology storage schema is designed according to OWL ontology characteristic.The existing design is improved by setting up separate class table,appending relational restrict table T-restrict.As a result,the storage of OWL classes,properties and the complex relations among them is easily realized.Lastly an example of school OWL ontology storage has indicated that the storage method is simple.The query test has proved that the retrieval efficiency is increased.All these explain that the design is feasible.
