Design And Implementation Of Online Investment System

With the rapid development of the economy,people's income increasing,and the innovation of financial tools changed people's financial management ideas and methods,personal financial market demand is becoming more and more intense.At present,most of the financial products concentrated on offline,which are low income,high threshold,low flexibility.At the same time,small enterprises and personal loans problem have not been effective solved all the time,and financing are very difficult.As bank services threshold is high,finance and loan's formalities are trival and complex,user's time and efforts are wasted.Besides,financial services does not reaching the designated position,and the existing system does not meet the personal finance market and the vast market demand in microfinance.With the rapid rise and development of Internet finance,the Internet financial management system arises at the historic moment,so the loans and financing problems can solve easily.The design and development of this thesis has great practical significance.From investigated the current financial market and found that deficiency of the current financial management system,considering the existing Internet technology and online investment and financing needs,the Internet financial management system is developed.In this thesis,we have designed and implemented three modules independently.First,the account management modules such as user registration,logging,setting up,investment management,setting security and so on.Second,the loan management modules,such as business and risk department auditing the enterprise's loan,releasing project after approved,managing the product in the process of investment,and loaning to the user after full.Thirdly,the investing and financial management modules,such as the user checking the project,security and other investor information,and investing the project.The main work accomplished in this paper as follows:First,we analyze the system requirements.Determining the necessity of development of this system through the feasibility study,combined with the feature of the user and market characteristics,collecting data with reasonable analysis,we analyze the product features and user characteristics of the system,determining the use case models,and expounding the functional requirements and non-functional requirements of the project.Second,the system overall design is given.According to the requirement analysis of system,we design the system functional architecture and technical implementation architecture,at the same time,designing the database of the system.Third,we give the system detailed design,implementation and testing.We use Groovy language to implement the Internet financial management system,using modular design scheme to improve the flexibility and expansibility of the system.Based on the requirement analysis and overall design,we design and implement various modules in detail.We build a test environment to testing the function and performance,to ensure the system function and performance meet the requirements.The test verifies the system effectively solves the financial management not convenient and loans difficult problems.The users can select and invest products convenient,mastering the movements of funds and increasing wealth.The loans procedure and materials are simplified,small loans becoming convenient,and the short-term funds shortage problem effectively be solved.The system operation is simpler,flexible,practical,safe and stable,and the interface is aesthetics.The demands of the user's online investment and financing be met,and the user experience greatly improved.
