Abstract
Multi-database mining has been already recognized as an important and strategically essential area of research in data mining. In this chapter, we discuss how one can systematically prepare data warehouses located at different branches for ensuring data mining activities. An appropriate multi-database mining technique is essential to develop efficient applications. Also, the efficiency of a multi-database mining application could be improved by processing more patterns in the individual application. A faster algorithm could also contribute to the enhanced quality of the data mining framework. The efficiency of a multi-database mining application can be enhanced by choosing an appropriate multi-database mining model, a suitable pattern synthesizing technique, a better pattern representation technique, and an efficient algorithm for solving the problem.
