Design And Implementation Of Order Fulfillment System Based On Community E-commerce

With the continuous development and innovation of science and technology,the business model of e-commerce is constantly changing.From the initial platform-based e-commerce to the new retail,the development of e-commerce in China has entered the 3.0 era.Since the second half of 2018,a new business model "community e-commerce" of the community scene came into being.Its appearance not only opened up the fresh market which has always been difficult to touch in the e-commerce field,but also provided strong strategic support for major e-commerce platforms in terms of channel sinking with a higher ROI(region of interest).The community e-commerce breaks the traditional B2C model and cooperates with the convenience storekeepers through community group-buying.In order to reduce logistics costs and enable consumers to buy better goods at a lower price,the orders of the community users in the community group-buying activities will be delivered to the convenience storekeepers once and for all.First of all,the paper introduced the background of the project and the development status of community e-commerce.Secondly,it carried out a comprehensive and detailed demand analysis of the system.And then,it completed the system architecture design,module division and database design.Finally,the paper elaborated on the detailed design and implementation of the system,explained the test and maintenance and made a summary and outlook.In the process of system development,the author independently completed the design and implementation of the order pipeline module,order production module,order distribution module and order monitoring module,and participated in the requirements analysis,architecture design and test maintenance work of the system.The system adopted MVC design mode and SSH technology framework in research and development,data storage by MySQL and Redis database,and deployed the system on Nginx server.These technologies improved the efficiency of agile research and development and system reusability,and reduced system coupling degree.In terms of system function,order information has been transferred in four modules:order pipeline,order production,order distribution and order monitoring,which supported the complete transaction process of user order placement,commodity production,commodity sorting and distribution,and order fulfillment.Firstly,the order pipeline module generated complete order information through interaction with other systems.Then the order production module realized the functions of order splitting,transferring and time-effectiveness calculating.Next,the distribution order processing and final fulfillment are completed in the distribution module.At last,the order monitoring module analysed the data to provide a strong guarantee for business growth.In terms of system performance,the TPS index of the system is increased through sub-database,sub-table and added front entrance of the order pipeline,which ensured the smooth operation of the system under high concurrent traffic pressure.Since the order fulfillment system came online,it has experienced three high concurrent traffic tests of shopping festivals:"618","Double 11" and Annual Merchandise Festival and the system keeps running smoothly.The number of users has now exceeded 800,000,and the daily average order volume and the GMV index are leading the market.
