Abstract

Two approaches for integrating heterogeneous database schemas based on the concept of a global schema are surveyed. The first approach relies heavily on manual resolution of various incompatibilities, particularly semantic, that exist among different local database schemas. The second handles this resolution automatically. In this work, usage of an on-line general taxonomy as a tool for resolving various incompatibilities among component schemas is introduced. This tool is a part of an on-going research for developing a new methodology for integrating heterogeneous database schemas using an on-line general taxonomy. Many advantages offered by the tool are discussed.
