Design And Implementation Of Foreign Trade Trading Platform

With the advent of the information technology era,the drawbacks of the traditional foreign trade industry have been exposed in such a fast-developing environment.On the one hand,it is difficult to form a concentrated market due to few buyers and sellers.When buyers and sellers negotiate privately to reach an agreement,negotiation skills has a great impact on the final price.On the other hand,the price formation is not standardized and the risks cannot be transferred.Since the contract price is based on factors such as the supply and demand situation at that time and the change in the market price as contract executed is inevitable,it is obvious that one party will lose benefits compared to the other party.At the same time,the formation of prices is also largely limited by geography,which makes it difficult to form a fair price.In order to keep the foreign trade industry's procurement transactions accurate and efficient in real time,buyers and sellers urgently need a procurement trading platform that can provide real-time and accurate services.In this paper,in response to the design and development of the procurement trading platform,the requirements analysis,summary design,detailed design,code writing and subsequent testing on-line work of several modules of the project were completed.In the demand analysis stage,through the questionnaire survey and in-depth interviews with customers,the corresponding data was collected in the early stage,and the overall demand and strategy of the products were clarified.In the outline design stage,through the summary of the previous requirements and the design of the functional flow chart,the overall implementation of the system was clarified and the specific layout was determined.On the basis of completing the summary design,by classifying the main business of the system,engineering drawings,flow charts and class diagrams[hl]of the modules of different services were drew to assist in the completion of the code writing.After the codes were written,the corresponding test cases were designed for the logic part of some internal main code to complete the test of the system.The procurement trading platform uses Java EE for code writing,adopting the classic MVC pattern for development,and separating the business model,controller,and interface.Based on the idea of MVC,considering the performance of the platfonm,the project uses SpringMVC as the most basic development framework for request forwarding and view management.Mybatis acts as a data link framework to persist data objects.The system is used with Nginx as the server,and Mysql is used as the database of the platform to store related data tables.At present,the procurement trading platform has been launched,which can meet the needs of most users engaging in cross-border foreign trade procurement transactions.This can greatly facilitate users to conduct real-time purchase transactions without leaving home.
