The Trade System Of Futures Design And Implementation Based On The Framework OFBiz

Futures exchange is the transaction of the futures, if it is buying or selling. In other words, futures exchange system is a complete process to complete the buying or selling procedures for futures exchange by computer.A complete future exchange system should have two parts, one for the procedure of exchange, and one for the management of all the procedures. The first part for the trade system is based on the memory match technology to achieve the largest response speed. The key technology is that all data deposit in the relational database but the transaction core code is not communicated with the hard disk directly after the system started. After the system started, the data used in the exchange is called in the read-only sharing memory only once. After that, the transactions reconcile, the production request list, the transaction results, all are realized in the memory. When the transaction is completed, the results from the transaction will be wrote to the database on the hard disk. In the database to facilitate the transaction clearing, sorting, and various accounts and produce statistical reports, meanwhile, again through a variety of input and information changes. The second part for the transaction system is web-based, and uses some type of framework. This paper describes the design and implementation of the second part of the trade system of futures based on the OFBiz framework.This paper in the first chapter describes the concept of futures and the J2EE technology and the MVC design pattern. Chapter 2 first introduces the OFBIZ framework based on this pattern, and then describes the OFBIZ framework for a detailed description. Chapter 3 introduces the needs of the project. Chapter 4 describes the system framework designed for it. Chapter 5 makes a detailed description of the trade system of futures design and implementation. Chapter 6 writes the key technologies and the security problems of the system. Chapter 7 gives out the system testing data and testing results. Finally, I write the system development process and make a summary of my views on the trade system of futures based on the J2EE technology.
