The need of effectively managing the data sources of an organization, which are often autonomous, distributed, and heterogeneous, and devising tools for deriving useful information and knowledge from them is widely recognized as one of the challenging issues in modern information systems. Ontology-based data management aims at accessing, using, and maintaining data by means of an ontology, i.e., a conceptual representation of the domain of interest in the underlying information system. This new paradigm provides several interesting features, many of which have been already proved effective in managing complex information systems. On the other hand, several important issues remain open, and constitute stimulating challenges for the Knowledge Representation and Reasoning research community. In this talk we first provide an introduction to ontology-based data management, illustrating the main ideas and techniques for using an ontology to access the data layer of an information system, and then we discuss several important issues that are still the subject of extensive investigations, including the need of higher-order modeling capabilities, inconsistency tolerant query answering methods, and mechanisms supporting update operations expressed over the ontology.
