Towards a Flexible Database Interrogation
Ines Fayech · International Journal of Database Management Systems · 2012
In this paper, we are interested in the use of domain ontologies as a semantic enrichment for traditional databases.Our first aim is to help the user in his search when his initial query doesn't return any result.So, we propose a solution based on two different approaches allowing the user to express his interrogation in a relatively free way.The first approach detects and resolves naming and schematic conflicts.It is an ontological approach for SQL query expansion generating a set of queries.The second one is a join detection approach to eventually add all missed constraints in each generated query.
