The Design And Implementation Of Loan Management System

With the development and reformation of financial system, a loan-management system should be constructed to share the information and restrict operation within the rules and regulations. This paper focuses on the workflow of constructing a loan management system which is safety, efficiency, standard and easy to be operated.The loan-management system is developed on J2EE platform which is in accord with the requirement of MVC architecture. The proper system framework is set to separate the business-expression code from view-expression code. Thus, system's development and maintenance are simplified. And by using the design patterns, it is easy to realize certain function. The system not only has good expansibility, but also keeps robust.The configuration and deployment of web application is realized by using XML files. The front controller based on Servlet technique and transaction manager are used to achieve the controlling strategy. Database connection pooling technique and data cashing technique are used to boost the transaction efficiency and throughput. The Stateless Session Beans are used to achieve the business logic and the Entity Beans are used to access database system.The whole procedure of building an application system is explainedin this paper. Analysis, design, and writing operands are important stages in developing software system. During different stages there are different goals and assignments. By the construction of a loan-management system, the basic principles to build a system based on J2EE platform are demonstrated.
