| Abstract: | Focus on TB Level massive financial reconciliations file approximate comparison problem, this paper researched a number of the financial reconciliations file features to enhance the mass data comparing speed in financial sector, and proposed a multi-level approximate comparison model-UpCompare Model. UpCompare Model is a kind of multi-process technology based on hash index table, using fast winning strategy as the core algorithm, effectively solving the massive financial reconciliations file approximate comparison problem. Experimental results show that, by using UpCompare Model, bank transaction settle system efficiency improved more than 5× in daily financial reconciliations file approximate comparison. |
