Dr. L. Venkateswara Reddy, Dr. A.K. Damodaram

Abstract


Removing duplicate records in the relations of a database is an essential operation and it is a crucial and a critical step in the data integration. If the record duplication problem is unmanaged or miss managed it leads to poor quality, consistency, integrity of data. The present paper reviewed the problem contexts of data duplication and the techniques available for the management of the problem. This work also proposed some improved techniques to deal with data duplication problem. A set of data fusion techniques are proposed. A new way of data propagation is presented that should follow the fusion result to maintain data consistency.
