From Relational Databases to Ontology-Based Databases

摘要

Nowadays, the volume of data used in an information system grows rapidly. Additionally, enterprise information systems are more open to distributed environments and platforms. Thus, the need for interoperability between the different underlying data sources increases considerably. Therefore, data storage should consider storing data as well as the semantic of it in a single database. To overcome this problem, Ontology-Based Databases seem to be a good choice to replace legacy databases. In this sense, this paper proposes a reverse engineering approach which transforms a relational database to an ontology. The extracted ontology is enriched with more semantics by mean of external domain ontology. Finally the ontology and data are stored in one of the existing specific architectures for Ontology-Based Databases.
