Mining Multiple Large Data Sources

Effective data analysis using multiple databases requires highly accurate patterns. Local pattern analysis mightextract low quality patterns from multiple large databases. Thus, it is necessary to improve mining multiple databases usinglocal pattern analysis. We present existing specialized as well as generalized techniques for mining multiple large databases. We formalize the idea of multi-database mining using local pattern analysis and propose a new generalized technique formining multiple large databases. It improves the quality of synthesized global patterns significantly. We conduct experimentson both real and synthetic databases to judge the effectiveness of the proposed technique
