Abstract :
Schema matching is a crucial problem in Data Integration and Data Translation. In this paper, a pretreatment algorithm is proposed, which is an optimized and improved algorithm for the previous schema matching algorithm on opaque column and data value. Thus, the calculation of previous algorithm is decreased greatly, the time of the execution, the efficiency and precision of schema matching is enhanced.
