| Abstract: | An attribute integration approach based on fuzzy set theory is presented.It can explicitly represent the inconsistency extent of data attribute values in database integration systems.An introduction is also given to a semantically richer and extended structured query language.Finally,an attribute integration approach used in multi database integration environment is described by examples.It applies to a variety of application environments. |
