On The Potential Integration of an Ontology-Based Data Access Approach in NoSQL Stores

NoSQL stores are emerging as an efficient alternative to relational database management systems in the context of big data. Many actors in this domain consider that to gain a wider adoption, several extensions have to be integrated. Some of them focus on the ways of proposing more schemas, supporting adapted declarative query languages and providing integrity constraints in order to control data consistency and enhance data quality. The authors consider that these issues can be dealt with in the context of Ontology Based Data Access OBDA. OBDA is a new data management paradigm that exploits the semantic knowledge represented in ontologies when querying data stored in a database. They provide a proof of concept of OBDA's ability to tackle these three issues in a social application related to the medical domain.
