Integration is commonly used for summarizing information held in very large databases which are encountered in data warehousing, large scale transaction management, and statistical databases. Such applications often involve distributed databases that have developed independently and therefore may exhibit incompatibility, heterogeneity, and data inconsistency. The authors are here concerned with the integration that has heterogeneous classification schemes where local ontology's, in the form of such classification schemes, may be mapped onto a common ontology. Existing transaction protocols typically rely on compensating transactions to handle exceptional conditions.
