Research And Implementation Of FSH Hierarchical Architecture On RIA WEB Application

With the development of Internet, the WEB application system has been used more widely. The traditional WEB system which based on HTML has many shortcomings such as slow responding of software,weak interaction, and unfriendly user interface and so on. In order to solve these problems, a new technology RIA was presented, as some RIA implementations, like Flex. Moreover, the increasing demand of WEB application system results in the development cycle to be getting more.urgent, how to develop good scalability, reusability, and easy maintenance WEB applications in the shortest period is also the problem which urgently wait to be solved.For these problems, the thesis studied RIA deeply and made detailed analysis of Flex technology and Cairngorm, PureMVC framework, Combined with Spring and Hibernate, then proposed the FSH hierarchical architecture which was used in RIA WEB application system development. The architecture:has the following advantages:(1) In view of Cairngorm framework for Flex had complex structure, the thesis simplified Event mechanism on the Cairngorm framework. Besides,the thesis realized the code reusability by optimizing service call further.(2) Combined with hierarchical thinking of WEB Development, give full play to Flex in the presentation layer, the business layer utilized by Spring, Hibernate was applied to the database persistent management. Thus, RIA WEB application which based on FSH hierarchical architecture achieves the optimization in every level.(3) FSH hierarchical architecture reduced coupling between layers in system development process, improved the efficiency of system development and enhanced the maintainability of system.Finally, FSH hierarchical architecture successfully applied to design and implement VTS management information system The practice shows that the FSH hierarchical architecture in RIA WEB application development gave full play to the advantages of each layer, reduced the complexity of development, thus solved the problems of traditional WEB applications.
