Abstract

Background and Objectives: Relational Databases have got such a great importance in the current global enterprises, such that they are widely and extensively used for storing and managing data. The objective includes the comparison techniques with older approaches and present approach depicts best accessibility to read/write access to the data. The data semantics are not directly imposed on the relational schema. In fact, they are direct towards the application level. Methods/Statistical Analysis: There are several mapping techniques involved by many semantic web technologies and several ontologies that enhance data utilization among many applications. The techniques also embed data reusability for many number of times across community boundaries, large enterprises etc. The current strategies depend on the Read only access either through Linked data or SPARQL. The implemented approach underwent the test cases with various instances using interfaces. The interfaces falling under semantic web frameworks for accessing of data by these approaches include RDF2GO: ChangeSet, Sesame and Jena. Findings: The feasibility factors for conversion of relational data schema to the RDF do not give satisfactory remarks. Hence, to increase the feasibility scope for conversions, we used and adopted an approach called “Mediation Approach” for converting RDF’s to RDB’s. In the current context we present an extensible platform called RDB-to-RDF Ingression (R2RI) that supports Read/write access to the data residing in the relational schema. The entitled platform uses the technique of “encapsulation” as the translation logic during translation process in the core layer. This translation logic proves itself to be the foundation for the rest of the interfaces existing in the interface layer. At later stages, we exposed the general concepts about the architectural patterns, mappings of RDB-to-RDF and emphasizing special focus on our mediation platform “R2RI” duly enhancing a protocol to provide parsing feedback protocol to the client. We also present the prototype implementation process followed by its performance calculations.
