Design Of Information Delivery System's Framework And System Integration

As the development of the information technology, more and more financial system is upgraded into information system. Their application will be published to customers via the Internet directly. This paper is to analyze some problems in such a typical Web application of financial information delivery system at the design process, and provide some useful solution to the problems. In this paper, based on the analysis on not only the presentation layer, business logic layer and persistent layer, but also twos subsystem of report delivery system and full-text search system, I introduce the technology of Struts, Spring, EJB, JMS, Web Service and so on. In addition, the financial system often requires data from different database. In this paper, I introduce one solution which is based on Actuate ODA Driver and the OSA system. Through this approach, the reports in our system are able to share their data across multiple database system, and its development process is very easy. Finally, to integrate the current system with the other two subsystems, we have studied and compared two integration technologies the SCA and Web Service Client according to the difference in performance and extensibility. In the system integration, based on the findings of these studies, we could choose a suitable system integration technology, and then more services will be integrated into our financial information delivery system.
