Design And Implementation Of Real-time Stock Guessing System

In recent years,the continuous development of Internet in the financial field makes it undertake more important tasks,especially in the stock trading activities.The demand for stock trading has contributed to the formation and development of the stock market.The shareholders,as a backbone force,have been witnessing and participating in a series of changes and developments,while the independence of stock speculation makes the shareholders lack of communication and real-time communication.The price of adjacent stock transactions will serve as an important indicator for the next investment of stock investors.The trend and dynamics of the price can be used to predict the future stock trading situation.The establishment of the stock real-time guessing system can make the stock investors grasp the information of the stock situation in time,understand the current investment trend,and provide real-time communication and analysis and prediction of the stock trend services for the investors,solve the problem of the asymmetric investment information of the investors,and promote the rapid and stable development of the stock market.The real-time stock guessing system includes two parts: the client system and the data service system.Stock real-time guessing client system for investors to participate in short-term stock rise and fall real-time guessing,check the stock development situation information and real-time communication of hot topics.Data service system for statistical analysis of user guessing data,the release of the current guessing stock related hot information,statistical guessing ranking information.This thesis through to the stock quizzes real-time systems analysis and design,in the full understanding people personnel demand,on the basis of users and data analysis based on Transmission Control Protocol(TCP),Transmission Control Protocol)specification to transmit data information,the use of the Objective-C language programming to realize system functions,define the application based on Socket technology through the network Protocol communication interface,using MySQL database as a relationship management system,the data stored in different tables,increase response speed and improved the operating flexibility,Finally,a stock guessing system with excellent performance,real-time stability and good experience is designed and implemented.At the same time,based on the asymmetric encryption technology encryption to ensure the security of the system operation,and build a system test environment,the system function and performance test,users can complete the stock guessing,instant chat and other functions,when the user access to reach the expected limit can still be normal operation,to achieve the desired effect.The system has achieved the original design requirement through the complete function test and performance test.This software is a good solution to the current market of similar software in real-time,system instability and security can not be guaranteed and other problems,so that the user's guessing trading experience has been greatly improved,with a very good practical significance.This thesis mainly completed the following work: first,introduce the system research background and current situation analysis;second,introduce the main technology used in system development;third,carry out system requirements analysis and functional modules and development;fourth,carry out functional testing;fifth,summarize and analyze the system problems and put forward the direction of improvement.
