Abstract


Online securities trading system to the Internet as the basis, transaction -driven securities company for investors to provide securities trading system . The system can support a Securities Investor Account Login stock inquiries , stock balance inquiries , stock purchase transaction queries a full range of business functions . With the deepening of network applications , online securities trading has become the major transactions in the stock investors . This thesis, Tuxedo middle layer , the characteristics of online securities transactions , the development of the embodiment of the system , modular design methods , online securities trading system to achieve a three-tier C / S structure . The drawbacks of the system effective solution to the burden on the client and server side overweight , poor scalability , can not across different platforms , the system difficult to maintain two-tier C / S structure . The system consists of three parts of the client , the server-side and back-office resources manager . The client uses the Tuxedo Workstation Subsystem client mode and C as the development language . Client using the model simply install Tuxedo Workstation Subsystem components . Tuxedo provides an API used in conjunction with Tuxedo and server can communicate . The server side using the Tuxedo server programming model for the development of language , C and Embedded SQL . Taking into account the problem of portability of the system , a large number of server-side API provided by Tuxedo . Server-side using the Tuxedo transaction manager server (TMS) to manage the overall affairs and forward client requests to use load balancing technology . The back-end Oracle database as a resource manager can actually use any database that supports XA specification as a resource manager . The system has the following characteristics : (1 ) efficiency : the system uses load-balancing technology Tuxedo forward client requests to ensure that client requests in the shortest possible time to get treatment . ( 2 ) Safe and reliable : the same server running on multiple hosts at the same time . So that when a host fails , the server running on the other host can still provide services . (3) easy to extend : the service can be updated without shutting down the server and launch a new service . ( 4 ) Ease of maintenance : the extensive use of the API provided by Tuxedo system has good maintainability .
