The physical level implementation of web data model specifies the overall configuration of the conceptual model and its necessary mapping to existing logical model for delivering the functional and non-functional requirements of any web based information system. In our previous work [1, 2], we have proposed a graph semantic based data model, Extended Graph Data Model (EGDM) that conceptualizes the business environment components with high degree of understandability. But the design of such complex system not only demands a strong conceptual model, also a proper framework is required to offer a "doable solution". In this regard suitable model-based engineering tools and related customization is essential for traceability of the specified requirements. In this paper, software technology based specification and the concerned configuration process has been discussed for our proposed data model EGDM. The necessary mapping rules and an interpreter based on those rules have been developed to convert EGDM into Product Specific Model (PSM) using SQL: 2003 standard.
