Design And Implementation Of The Stock Trading System

The current social stock enthusiasm, more and more people choose stocksas a way of finance and investment. Stock market data exist large anddiscontinuous features, however, rely entirely on personal experience or a simpleanalysis of stock market data to forecast the development trend of the stockmarket is clearly unrealistic. Therefore, the use of stock analysis software toanalyze stock market data, in order to assist investment in no doubt make theinvestment more scientific and more stable. Analysis and management ofcomputer information processing tools applied to the stock of information hasbeen rapid development in computer technology today, more and more common,and this will also bring a lot of stock enthusiasts convenient..Stock analysis software currently in circulation on the market, they have thesame advantages, that is powerful and complete design. Precisely because so,making the operation of such stock analysis software is very complex, industryprofessionals with considerable experience in the amateur stocks able to skillfullyuse for the majority of individual investors, often only confuse the fans in anumber of chart array, and can not get the information they want to design asimple and easy to understand and can give users investment advice stockanalysis system is very important.From the choice of system development is divided into a total of three parts:The first is the way of client development, system development has two types ofthe most widely used architectural pattern, the B/S mode and the C/S mode,the two modeshave their own advantages and disadvantages, such as C/Smode for LAN, B/S mode can meet the needs of the user as long as the localnetwork can use the system, maintenance of C/S mode is more difficult than B/S modeTherefore, the advantage of stock analysis system needs, and B/S modeon the basis of this selection is based on B/S model development systems. Then the choice of application-layer development, first by comparison of the existingplatform analysis to select the C#. NET-based platform technology developmentsystem, in order to improve code reuse, and reduce system developmentcomplexity, this paper introduces a three-tier framework technology to achieve aneffective separation of the presentation layer and business layer. Finally, theback-end database of choice, taking into account the stock analysis system dataand SQL Server2000database access on the basis of data and high efficiency,the paper decided to use SQL Server2000to the data storage system, acombination of the advanced technology for stock analysis system successfuland has laid a solid foundation.System analysis phase, through the systematic investigation of the sametype of analysis and research on the stock of business processes for the systemto determine the final design of the principles and objectives. And then use theuse case diagram of the system functional requirements analysis, system isdivided into the account management module, the user management module, thestock management module, the stock exchange module and the newsmanagement module to the modular design concept, and on this basis clearly thetype of user of the system as well as all types of users have authority to operate.In the detailed design stage, through the analysis of the operationalprocesses of the system function to clear the activity diagram of the variousmodules of key functions. Meanwhile, in order to give investors more effectiverecommendations, this paper designed a stock prediction algorithm, the algorithmcan predict the stock will rise or fall, in order to reduce the risk of damage by theshareholders investment. Then, on the basis of the needs of the known system,the system database, detailed design, database design process consists of threeparts, namely, conceptual design, logical design and physical design. Stockanalysis system is involved in the transfer of funds, in order to improve thereliability of the system, the paper system security design, first the user mustenter the system after system certification; different user permissions inconsistentto prevent unauthorized operation with each other; database reliability designed to prevent the data can not be restored due to unexpected failures..Finally, introduction to system implementation, this chapter introduced thesystem to achieve public class design, and key functions to achieve two parts.First, in order to improve code reuse rate in the system design, module commonfunctions extracted as a public class. Were highlighted and then the login functionof the system, the stock inquiry function, the stock information browsingcapabilities, as well as the management center functions. Finally, the completedand system shortcomings in this article are summarized.
