Xiangbin Gao, Dantong Ouyang, Yuxin Ye · 2015
Based on the vast domain resources of RDF(S) on the web and SPARQL’s powerful query ability, this article presents a new method of designment of E-R model. The steps for this design are: (1) Formulating SPARQL rules (including resource query rules and schema query rules) by the analysis of RDF(S)’s structure. (2) Parsing the optimal resource obtained through the query sentences. (3) Completing the designment by taking advantages of the translation from RDF(S) model to entity-relationship model in accordance with the content queried. The results indicate that, the designment of E-R model based on RDF(S) could restore user real requirements of great possibilities and help database designer to complete design in a strange area.
