Abstract: The main issue while handling records in data warehouse or cloud storage is the presence of duplicate records which may unnecessarily test the storage capacity and computation complexity. This is an issue while integrating various databases. This paper focuses on discovering records, entirely and partly replicated, before storing them in cloud storage. This work converts whole content of data to numeric values for applying deduplication using radix method. Fuzzy Expectation Maximization (FEM) is used to cluster the numerals, so that the time taken for comparison between records is reduced. To discover and eliminate the duplicate records, this paper used divided-and-conquer-algorithm to match records among intra-clusters, which further enhances the performance of the model. The simulation results have proved that the performance of the proposed model achieves higher detection rate of duplicate records.
