Design And Implementation Of Reinsurance System Based On J2EE Framework

The reinsurance system is a very important internal system of the insurance company. The re-insurance system has very important effect in avoiding risk of insurance company. With the development of the re-insurance business, the insurance company needs a new re-insurance system, and the new reinsurance system could achieve all the new functions of new re-insurance business. And the new re-insurance system will use new computer technology to make the system easy to expand and maintain.On the basis of analysis and study of the functionality requirement of the re-insurance system, the characteristics of MVC design patterns and various technologies used in the web application and development at present, according to the feature of the re-insurance system, the article defines the functional goals of the system, specifies the multi-tiers web system architecture used and proposes a solution to how to use multi-technologies and constructed the application framework properly. And following object-oriented software engineering philosophy and through the demand analysis of the system. The object-oriented UML (Unified Modified Language) has been used in the system's analyzing and designing phases. The system is based on B/S architecture and has been realized by Java technology. JSF framework was adopted to realize the MVC pattern. JSP was adopted to realize client layer. FacesServlet was adopted to realize controller. JavaBean was adopted to realize the service logic. Hibernate was adopted to realize the persistence layer which package the database access operation of JDBC and offer object-oriented data access API to the preview layer in order to hide the bottom operation and make the system have well multiplexing.The reinsurance system realized the function properly through using JSF and Hibernate technologies. The system satisfies the requirement of enterprise application and makes the system easy to expand and maintain through using multi-tiers system architecture.
