Design And Implementation Of Financing Guarantee Business Management System

Financing guarantee loan has become one of the important ways to raise funds for investment and entrepreneurship.Throughout the domestic lending business,they offer are petty loaning.The loan amount is limited.The interest rate of repayment provided by private lending institutions does not have a certain standard.Under these circumstances,the paper uses Activiti,REST and Mybatis and so on to develop the financing guarantee business management system,which implements pre-loan investigation,acceptance and review of loans,making loans,and after loans related business functions.It makes complex business processes in the loan standardized.The time for processing business is also reduced.First of all,this paper investigates and analyzes the business process and user requirements of financing loans.It models functional requirements using use case technology,including pre-loan investigation,acceptance and review of loans,making loans,after loans and so on.It also defines non-functional system requirements including performance and compatibility.On the basis,the paper applies layered style to proceed the architecture design.The system is divided into the presentation layer,control layer,business logic layer and data persistence layer.The composition and relation of each layer is described in detail in this paper.The system uses Restful Web Service technology,and supports two kinds of clients: browser and mobile APP.This paper has carried on the system deployment design and the database ER diagram design.Then JQuery,JSTL and JSP are used to implement web pages displayed.It implements data interaction between control layer and business logic layer.Activiti workflow engine has been used to implement pre-loan investigation,acceptance and review of loans,making loans,insurance checks and compensatory repayment of after loans.Activiti timed task event is used to implement risk-early warning mechanism triggered by timing.Mybatis is used to implement database access control.At last the functional testing and performance testing of system are carried out.It has carried out system function testing manually.All use cases are covered.It has carried out performance testing with Load Runner tool.The test results show that the system has rich functions,and its performance has reached expected goal.
