证券资讯信息平台设计和实现

【Abstract】wWw.shuoshilunwen.com The fields of securities and financial contains a very large amount types and quantities information, including the Securities real-time quotes which generated each day from Exchange, information news, trade statistics of finance, etc. It also has a lot of information analysis of institutions, securities companies, fund companies’ researcher who released the analysis of articles, research reports. The amount of data are so much, and the distribution of data types are so wide, making investors need from many different places access to information in order to carry out a complete analysis of statistics, making it difficult to grasp the latest trends in the securities market, lead investors hard to make rational decisions. With the development of information technology, and in-depth analysis of the securities industry, it’s urgent to need a broad array of disaggregated data collation with the latest information technology, and based on the perspective of investors to organize data into a software application platform, and can be through such a software platform for convenient, comprehensive, and effective information data browsing securities research, analysis and judgment, which can make the most rational investment decisions.This paper first analyzes the status of the securities news and information platform, and compared to other vendors in the domestic market to analyze its strong-weak duality and problems, and briefly describes the advantages of the system. Then fully described the system’s overall structure and working principle, and for the overall model of the scientific and rational design and development with modern software engineering way of thinking and design principles, as well as in the platform appears relative convenient and simple on system maintenance and upgrades. In this paper, the various key technical points are comprehensive and detailed analysis and research: In order to solve a variety of complex data model can be integrated into a unified information platform, the system uses the core platform and plug-in technology systems way of thinking, through a comprehensive core system platform provides a standard interface specification, making the business plug-in different data models can be convenient, integrated into the unified information platform up, but also to facilitate the upgrading and maintenance of late. For the coordination of data between the server and client communication and data traner, define the data traner communication protocol and communication interface. In parallel as possible to increase the efficiency of service and connection reliability, design an efficient parallel communication unit, as well as the communication load balancing strategy. To enhance data service system and user terminal information platform for data communication between the speed and reduce traffic, this paper, a detailed analysis of the special nature of the securities information and data, in the work of their predecessors based on the expansion of a new structural data based on a dedicated compression algorithm, and the design idea of this compression algorithm and realization method to do a detailed analysis and explanation, in order to determine the pros and cons of this algorithm, the test procedures and some mainstream common compression algorithm were compared. Finally, the paper test procedures through a number of ancillary information platform for the work carried out validation tests and appropriate place in the text marked with diagrams and instructions, while the adoption of the final software product screenshots and further explanation of the information described in this article, which shows platform has been widely in practice a formal application.IT software supplier for the securities-oriented investors to provide the highest quality products and services are the vast majority of software vendors source of profit for the same basic point, it contains a package of information design and development information, the integration of a variety of disaggregated investment data software platform, the majority of the securities business-critical IT software vendors point. And investors learn from this type of information the information platform to supplement their own investment decisions, improve financial market competitiveness. In addition, the system design ideas and resolve several key technical issues, also can serve as a general securities and financial software development enthusiasts learning and reference for the development of information technology make a modest contribution.
