Ontology Based Data Access (OBDA) is a recently proposed prominent approach that aims at providing domain experts with a direct access to available enterprise data sources without IT-experts being involved. OBDA is an alternative to centralised approaches, where an IT-expert translates the requirements of domain experts into Extract-Transform-Load (ETL) processes to first integrate the data and then to apply predefined analytical reporting tools. Currently, centralised approaches are commonly used in enterprises; they, however, can become too heavy-weight and inflexible in some cases, that can be addressed the OBDA approach.
