基于Flex和SOA的防洪调度管理信息系统开发

由于体系规模、软件架构模式、系统集成技术的不同,现有的水利信息系统在应用过程中往往存在数据难以整合、功能难以共享等问题,形成所谓的“信息孤岛”。面向服务架构（SOA）具有低耦合性、跨平台、易维护和可扩充性等优点,可通过良好的接口和服务实现数据整合和功能共享,可有效克服“信息孤岛”问题。基于Flex平台和SOA架构,开发了防洪调度管理信息系统,实现了地理信息服务、水文监测数据管理、防洪调度方案比选、洪水演进模拟等功能。从系统架构、关键技术、功能界面3个方面详细论述了系统设计与实现过程,可为今后水利信息化系统建设提供借鉴和参考。

Development of flood control management information system based on Flex and SOA

Due to the difference in the system scale, software architecture mode and system integration technology, the problems of difficult data integration and function sharing etc. exist in the current water conservancy information system, resulting in the formation of "information island". Service-Oriented Architecture (SOA) has the advantages of low coupling, cross-platform, easy maintenance and well scalability, etc., which can realize data integration and function sharing, and effectively solve the "information island" problem via sound interface and service. Based on Flex platform and SOA architecture, a flood control management information system is developed, which achieves the functions of GIS service, hydrological monitoring data management, flood control scheduling scheme comparison and selection, and flood evolution simulation. A detail introduction to the design and realization of flood control management information system is given from three aspects such as system architecture, key technologies, and UI to provide a reference for the construction of water conservancy information system in the future.
