Entity identification of fuzzy multidatabase systems with incompatible keys

Database schema integration is an important discipline for constructing heterogeneous multidatabase systems on one hand. On the other hand, fuzzy information has been introduced into relational databases and studied extensively. However, the issues of integrating local fuzzy relations are rarely addressed. In this chapter, we focus on schema integration of fuzzy multidatabase systems. In particular, we develop a method for identifying the entities in fuzzy multidatabase integration with incompatible keys.
