Design And Research Of High Concurrent Electronic Commerce System

In the development of E-commerce system, some problems have been encountered, first of all, the development of the system is mainly to solve the function problem because of the relatively small amount of user access.With the increase of user access, in the face of a large number of high concurrency, high load access, the system can't support such a situation. So resulting in a decline in the performance of the system, the response time is too long, or even collapse and so on. In view of these problems, it is necessary to reform, optimize and upgrade the system. This paper mainly from the following several aspects to research:Firstly, based on the study of the impact of high concurrency of the system on the hardware layer, hardware layer optimization scheme is proposed, including: using the load balancing technology to improve application server performance, using centralized storage technology to improve Session server performance, using the cache cluster and separate read and write methods to improve query efficiency.Secondly, on the basis of analysis the impact of software layer on the high concurrency, the software layer optimization scheme is put forward, including: Front-end optimization, database optimization and server configuration optimization. According to the analysis and comparison of the performance evaluation indexes before and after the optimization, it is proved that the optimization scheme of the software layer is reasonable.Finally, on the basis of studying the technology of electronic commerce system, an E-commerce system prototype system is developed. Including member management, sales management, product management, inventory management, personal center, system maintenance and other functions. Also completed the automatic code generation components, it can achieve the data increase, delete, change, search operations.Experimental results show that in high concurrency access, and the optimized prototype system in the second request, the number of requests to consume time and the number of failed requests and other indicators have improved significantly, the program has important practical significance to solve the high concurrent access to computer applications.
