Ontology driven query language for NoSQL databases

Most NoSQL databases have been devised independently from each other with specific application requirements. This has resulted in developing separate own data model and query language for each NoSQL database. The lack of standards in data models and query languages make applications and data less portable using these databases. Further, absence of formal semantics in query languages inhibits a precise understanding of query over NoSQL databases. To handle these issues, in this paper, an ontology driven query language for NoSQL databases is proposed. The proposed query language provides an efficient and common abstraction over the operational aspects on various kinds of NoSQL databases. The language includes formal common syntax and semantics of distinct query operators of NoSQL databases and those are represented in Description Logic. Further, usefulness of proposed query operators are proved using a suitable case study.
