DCUBE: CUBE on Dirty Databases

摘要：

In the real world databases, dirty data such as inconsistent data, du plicate data affect the effectiveness of applications with database. It brings new challenges to efficiently process OLAP on the database with dirty data. CUBE is an important operator for OLAP. This paper proposes the CUBE operation based on overlapping clustering, and an effective and efficient storing and com puting method for CUBE on the database with dirty data. Based on CUBE, this paper proposes efficient algorithms for answering aggregation queries, and the processing methods of other major operators for OLAP on the database with dirty dam. Experimental results show the efficiency of the algorithms presented in this paper.
