The designment and implement of rule matching algorithm in e_commerce application

E-business system with rules engine which is used by an enterprise is an effective option to reflect rapidly changes in the business and can make systems dynamic, speedy and efficient maintenance and upgrade when the subsequent business changes. Based on matching algorithm research on rules engine, the paper has improved and expanded Rete algorithm which has the high reputation both at home and abroad, has provided an improved rule matching model for the realization of rules engine, has certain innovation, high theoretical significance and practical value. This paper systematically analyzes how to realize Rete plus algorithm based on Rete algorithm and designs an improved Rete plus algorithm based on Rete algorithm.
