Design And Implementation Of Bond Investment Analysis System

At present,the A-share market in China's securities market is not performing well.Bonds have attracted more and more attention of investo rs because of their repayment,profitability,security and liquidity.Although many people begin to pay attention to bonds,there are few bond investment analysis services for investors on the market.How to provide bond investment assistance for investors is worth thinking about.The system described in this paper is an auxiliary bond investment analysis system.It mainly uses the data in the database to provide bond information query service for users.In addition,it provides calculation service for users by making bond calculator.How to provide users with good bond investment analysis services is the focus of systematic consideration.The main work of this paper is as follows:1.Considering that the basis of bond investment analysis is bond data information,we use PHP 5.6 to edit data acquisition instructions and collect bond data information on the target website on the Internet.In order to ensure the authenticity and integrity of data information,we choose bond data from Shanghai Stock Exchange websi te as data source.After data processing steps,the system provides bond data query service for users through bond basic information query and bond transaction information query.Users can use the bond data queried as a reference for investment analysis.2.According to the bond investment theory and the author's work experience,we select the more important reference items in bond information and design the bond calculator with personalized calculation method.From the income calculation,the maturity rate of r eturn calculation,the subscription rate of return calculation,three aspects to provide computing services.Users input the relevant operational elements and get the corresponding results after the operation.Through the comparison of the final results,th ey can make the investment income prediction,which is helpful for users to make bond investment decisions.The two service items of the system are realized through three functional modules: data maintenance module,bond information module and bond calculation module.Among them,data maintenance module is the underlying basic module,which provides data support for the whole system.The bond information module is divided into bond basic information query and transaction information query,which provides bond information for users to query by calling bond data in the system.The bond calculation module calculates according to the data provided by users,and displays the results of calculation.Ultimately,the system uses browser as client through B/S architecture,and users get services through Internet login system.After a series of tests,it is proved that the system runs well and the functions are normal.Users can obtain relevant data through bond data query and bond income calculator operation.The system can provide effective help for user's bond investment analysis,and has certain practical value.
