摘要
随着信息数据处理的要求不断提高，目前以三层体系结构为主的信息系统逐渐不能满足其需要，新增了数据预处理层地四层体系结构是未来发展的趋势。本文在概述四层系统结构理论的基础上，具体阐述了顸处理层的具体实现，并对其性能进行分析。
With the information and data processing requirements continue to increase,currently three-tier architecture based information system increasingly unable to meet their needs,new data pre-processing to four layer architecture is future development trends.This paper outlines four system architecture based on the theory in detail for the concrete realization of pre-processing layer,and its performance analysis.
