A Framework for Analysis of Ontology-Based Data Access

In last decade the terms related to Semantic Web become significant elements in the efficient way of information retrieval, processing and supporting availability of machine readable data. An ontology offers a wide spectrum of its application for data access. Ontology-Based Data Access is regarded as a key ingredient for the new generation of information systems, especially for Semantic Web applications that involve large amounts of data. OBDA system uses an ontology as a conceptual schema of the subject domain, and as a basis of the user interface for SQL database systems. This paper presents the complex overview of OBDA systems and a framework for analysis of selected tools for OBDA system creation.
