描述The problem of integrating multiple information sources into a uni?ed data store is currently one of the most important challenges in data management. Within the ?eld of source integration, the problem of automatically gen- ating an integrated description of the data sources is surely one of the most relevant. The signi?cance of the issue can be best understood if one c- siders the huge number of information sources that an organization has to integrate. Indeed, it is even impossible to try to do all the work by hand. Like other important issues in data management, the problem of integrating multiple data sources into a unique global system has several facets, each of which represents, “per se”, an interesting research problem, and comprises, for instance, that of recognizing, at the intensional level, similarities and dissimilarities among scheme objects, that of resolving representation m- matches among schemes, and that of deciding how to obtain an integrated data store out of a set of input sources and of a semantic description of their contents. The research and application relevance of such issues has attracted wide interest in the database community in recent years. And, as

Using the CIS Relative to ICGO Databasesthe system for constructing a query and for reading corresponding results. Finally, we illustrate some utilities provided by the system, such as an on-line help and a glossary..All material presented in this chapter has been derived from [38,40,39].

Generation-X Technologies and IT Auditing,ection, we provide a complete example showing how it works. In the last section of the chapter we compute the complexity of the presented algorithms and we prove that they are polynomial w.r.t. the number of objects belonging to the involved schemes..The material presented in this chapter is taken from [92,122,87,90,117,118].

The third section describes the second algorithm for deriving hyponymies and provides an example showing how it works..The material presented in this chapter is taken from [95,97,88].

G. Ferrando,F. Pigni,C. Quetti,S. Astutih we proposed and implemented in DIKE. The second section presents the context diagram of DIKE; the description of DIKE modules is carried out in the third section whereas in the last one we describe a “trip” through the system.}.The material presented in this chapter can be found in [121,94,93,99,102].
