Research And Realization Of Flood Control Application Integration Platform Based On Portal

Water resource is faced with new task in today's informatization situation. In this paper, from the point of flood control, the actuality and existing problems in flood control and the development of application integration in modern information technologies have been discussed. It is essential and necessary to build a flood control application integration platform, which should be the one to support information sharing, water resources integration and operation on different platforms.Portal technology is elaborated firstly. Portal is an application framework, an application system based on web, and it can integrate all kinds of information and knowledge from the enterprise interior and exterior through web component, which is called Portlet. Application integration must integrate information resources and applications to a whole of coordinated work. Portal's characteristics such as single visit mode, to integrate existed systems and individuation provide a favourable technology support for building an application integration platform. At the same time, application integration platform is applied widely to integrate enterprise information resources, which is also to be a powerful reference to apply this technology to water resource.Based on theories analysis above, this paper presents a whole architecture of the flood control application integration platform based on Portal. This architecture includes data integration, application integration and development method integration and so on, and it integrates successfully all flood control businesses to a water resource portal for supporting effective flood control decision. Besides, the design and built of integration platform are also elaborated. This integration platform is based on Portal framework, and utilizes data integration middleware to integrate existed databases from different structures and different places in water resource; utilizes Portal's integration characteristics to assemble one or moreflood control components to one flood control business, realizing flood control businesses'integration under Portal; utilizes flood control field application framework AAF to develop flood control application component Portlet. AAF accords with MVC design mode, which enhances code reuse rate and advances component development efficiency and quality, realizing the integration on development method.At last, this flood control application integration platform is applied to develop and actualized Shaanxi flood and drought control decision support system, which validates enough the superiority in applying the flood control application integration platform to develop rapidly the flood control decision support system.
