Abstract


With the current Web has evolved into Semantic Web research the next generation of portals - Semantic portals (ie Semantic Web technology driven portal) is an inevitable trend of development. The early development of semantic portals \However, the portals have developed using traditional Web development technologies inherent defects, makes the portal after the transformation of \With the Semantic Web ontology technology has matured, academia and industry presented some \develop a semantic portal and toolset also failed to meet the requirements of the \This article is in this context, to study and propose a \design) to conduct in-depth research, design and development of the corresponding of CASE tool O2DDesigner the prototype. O2DDesigner domain ontology according to the input, in accordance with the the predefined body to a relational database schema conversion rules and conversion algorithm, as well as body and the relational database schema (Onto-RDB) elemental mapping relationship between XML representation format and generate the relational database schema ( SQL DDL statements) and Onto-RDB the element mapping relationship (XML format). For the site engineer, the tool provides a friendly man-machine interface, analytic and visualization OWL DL ontology generated RDBMS type, site engineers can choose according to their own needs, the tool will automatically generate the corresponding relational database schema DDL statements and Onto-RDB elemental mapping between XML files. A typical case study to verify the feasibility of the conversion algorithm, Onto-RDB elemental mapping between XML format and have implemented a prototype tool validity; O2DDesigner results in a typical application of the semantic portal based on ontology the relationship between the relationship the database mode design and CASE4SWPD of framework.
