AUTOMATICALLY GENERATING A SEMANTIC MAPPING FOR A RELATIONAL DATABASE

摘要

Automatically generating a semantic mapping for a relational database RDB, comprising: obtaining a first semantic mapping from a first RDB to an ontology of linked data; obtaining a schema mapping from the first RDB to a second RDB; and generating a second semantic mapping from the second RDB to the ontology of the linked data based on the first semantic mapping and the schema mapping. Through this method and system, the efficiency of generating a semantic mapping for a relational database may be effectively improved.
