A Query Processing Strategy for Conceptual Queries Based on Object-Role Modeling
There have been several authors asserting that conceptual query languages (CQLs) perform better for querying purposes than logical query languages such as SQL. This paper proposes a query mapping algorithm for the FConQuer system. FConQuer is a framework based on object-role modeling (ORM) schemas, which allow the end-user to formulate conceptual queries through the FConQuer language. Our mapping algorithm allows the FConQuer system to process conceptual queries based on ORM schemas. More precisely, our algorithm maps FConQuer queries to OQL.
