The Design And Implementation Of The Securities On-line Transaction System

Securities on-line transaction system is the Information Management System oriented to securities investor in Securities Company to realize the securities business and investment management on internet. The system can support the securities investor to service the function of account register, securities buy, securities sell, stock remaining inquiry, fund remaining inquiry, stock quotation inquiry, request inquiry, deal inquiry, password modifies, bank to security account transfer etc.This article used Windows 2000 Server as the system platform and VC++ as the develop platform, Hengsheng enterprise transaction system as the backend service system. Securities on-line transaction system is programmed via VC++, using ODBC, Multi-Threading, Socket etc, which included Transaction Monitoring Module,Bank to Security Account transfer Module, Communication Module, Transaction Monitoring Module, Communication Monitoring Module,Transaction Retransmitted Module, Data Encryption Module, Management Module etc.The introduction and the state of art for the Securities on-line transaction were given and the main problems which should be solved were talked about. We also talked about the target, design rules, system architecture and system function modules, and analyzed the core business, user interface design, system interfaces. Also the techniques were provided.Here are the key problems:First, on the basis of the Socket communication techniques, the information system was used the multi-thread technology to implement many clients link and the concurrent access control. The technology can enhanced the application program response, caused the multi-processor efficiency to be higher, improved the program structure, takes the less systems resource, integrated system performance.This is advantageous for the distributional application.Second, with automatedly processed the falls of process, the system can controlled conveniently by the investor.Third, with 128 bit of DES encryption algorithm, the system can guaranteed the transaction security.Fourth, with VC memory sharing, the system enhances overall performance.
