WebIn ontology-based data access (OBDA), an ontology is connected to autonomous, and generally pre-existing, data repositories through mappings, so as to provide a high-level, conceptual view over such data. User queries are posed over the ontology, and answers are computed by reasoning both on the ontology and the mappings. WebOntology-based data access (OBDA) is a data integration framework where data is accessed using queries on the ontology layer, and in turn, a set of mappings guide the data access on the underlying relational layer. This process is usually done via query rewriting wrt. ontology and query unfolding wrt. mappings respectively.
