Design And Realization Of Securities Trading Front System

The trade front-system is a significant symbol of national security industry development.The old-fashioned Trade system has less efficiency,less liability and resource waste,so the market needs a more developed system to support the transaction.Based on the characteristics and the current situation of the securities trading system,the design principles and objectives that meet the actual needs are put forward,and the business process faced by the securities trading system is systematically summarized and sorted out.Under the guidance of the design principles and the overall business process,the functional and performance requirements of the system are analyzed in detail,which provides the basis for the realization of the design of the securities trading front system.In addition,combined with the actual situation,the analysis of the system development environment and operating environment are completed.In order to improve the efficiency and quality of service in the securities trading industry,and in order to meet the increasing demand of the securities industry,we designed the communication method based on reliable multicast to improve the transmission efficiency.Through the abstraction of the business process of the securities trading front system,the system architecture is designed in general.On this basis,the system is designed in detail,and the flow chart of the function module is given and the detailed description is given.In order to simplify the design flow,the software engineering theory is used to structure the requirements of the system in the preparatory architecture stage.The system is divided into business layer,fault tolerance layer and communication layer.To test the performance we designed a client order application and improve the encryption algorithm of the system.In the conceptual stage,the function modules of the partition are designed and the system is further simplified according to the principle of high-level segmentation,and some non-functional requirements are added to the design.The detailed design is based on the specific logic view Design,physical architecture design and so on.Using the C ++ programming language and the Visual Studio 2010 IDE development environment,the securities transaction front system and the client subsystem based on multicast communication are realized.At the last the paper showed the test results of the improvements.The test results indicate that the alteration of the trade front-system had achieved the expected requirements.
