A Middleware Framework is required for Semantic Web applications to access data from relational databases and legacy storage systems, without replication or synchronization. Resource Description Framework is one such type of middleware framework which bridges the gap between two needs. Though, there were some efforts to publish relational data as Resource Description Framework triples, they present the existing data into respective RDF stack only in Read-only manner, also in dearth of security. This paper accomplishes such in vulnerabilities by enhancing a nexus to be bi-directional, allowing data updates specified as triples to be sent back to the relational database as tuples. The data can be Updated/Inserted/Deleted wherever required. Also, this paper deals with the Level-1 and Level-2 security hierarchy. In those two levels, a random “salt” is added up to the data followed by encryption.

By the way of conclusion, this paper states bi-directional translation to relation database using RDF which is encrypted for a better security. Security is provided level by level. We can expect further better features added to RDF to make easy to access.
