Data integration provides the user with a unified view of legacy data, and the semantic mapping from relational database (local sources) to global ontologies is one of key aspects for building data integration system. The manual mapping is time-consuming and error-prone. In this paper, groups of semantic mapping rules from relational database to global OWL ontologies are proposed in detail, including rules for the classes, properties, restriction and instances, which avoid migrating large amounts of data. The rules are demonstrated with examples. They are practical for semantic mapping or ontologies learning (semi-)automatically.
