信息集成是企业信息化建设的重要内容，通过信息集成实现企业各类信息资源的共享与综合利用，突破局部应用造成的信息孤岛，实现企业信息流的畅通。 论文以水利枢纽应用为研究背景，针对当前企业信息管理的需要，研究信息及信息处理的集成，提出适合水利枢纽信息化中信息的柔性集成的新概念，并以此概念为基础，研究设计可做为领域内信息集成，提供信息集成服务的柔性信息集成平台，对柔性信息集成平台的模型、结构、实施细节作了较充分讨论，利用J2EE技术体系初步实现了柔性信息集成平台的框架及核心部分。 柔性信息集成平台是以CIMS理论中信息集成定义为指导，结合柔性软件系统和EAI技术，面向企业信息集成的内在需求，为使用者提供灵活的信息集成服务；平台提供公共信息处理功能的挂接机制，并具有按照信息处理流程可配置、可重组，提高信息处理单元适应环境变化的能力；系统以全局信息模型为信息服务的基础，内部实现全局模型与局部模型的映射，对外语义透明。 论文从三个大的方面进行了研究： (1)在分析了领域内信息集成需求以及水利枢纽信息化特点的基础上，研究了提供信息集成服务的，并适合信息化持久建设需要的具有开放性和可扩展性的柔性信息集成平台的系统结构。 (2)在分析总结EAI和柔性软件系统等技术特点基础上，提出了柔性信息集成平台(Flexible Information Integration Platform，FIIP)的核心模型。a)为了提供数据表达、数据结构、数据内容一致性的信息集成服务，研究了全局信息到局部信息的映射模型；b)为了复用相对成熟的领域内信息处理程序和逐步规范领域内信息处理流程，研究了软件总线结构下的公共信息处理单元的组织模型和业务流程控制下的信息处理单元之间协作交互模型等。 (3)在模型研究的基础上初步实现了FIIP的系统结构和核心部件。a)实现了基于J2EE的FIIP体系结构；b)实现了基于XML的信息处理与模式映射；c)实现了基于JMS的软件总线的数据处理单元之间的交互协作的机制。
A key point for informatization of enterprises is information integration, through which the sharing and management of various information within enterprises can be realized, the information insularity caused by regional application be overcome, and the stream of information be expedite.The paper"s research background is the hydraulic hinge. According to the current requirements of information management of enterprises, the paper studied the integration of information and information processing, proposed the new concept of flexible information integration, which fits the informatization of hydraulic hinge. Guided by this concept, the paper then designed the system used as a platform of information integration, and discussed the model, structure, and implementation details of flexible information integration deeply. Then we worked out an initial frame and core part of the flexible information integration platform using J2EE technology.Flexible integration platform provides the users with flexible information integration service, which is guided by the definition of information integration in the theory of CIMS, and combined with the flexible software system theory and the technology of EAI. The platform provides the connection system of public information processing, and is able to be configured, re-organized according to the processing order so as to enhance the ability of information processing units to adjust themselves to the surroundings. The information service of the system is based on whole information model, and realize the mapping between whole model and local model, which is semantic transparent to the outside.The paper makes the study and design from three perspectives:(l)based on the analysis of the demand of information integration and the characteristics of hydraulic informatization, provides a extendable and open flexible information system structure which fits the sustained construction of informatization.(2)based on the analysis of the technical features of EAI and the flexible software system, The paper studies the core model of FHP (Flexible Information Integration Platform) . a) studies the mapping models between whole and local information views. To provide the information integration service with consistent data expression, data structure and data content, b) studies the coordination model controlled by the organism model of public information processing unites and business flow under the structure of software bus.(3)realizes an initial structure of FIIP system and a core part based on the studies of the information model, a) realizes the FIIP structures based on J2EE. b) realizes the information processing and mode mapping based on XML. c) realizes the coordination between software bus based on JMS and data processing units.
