【摘要】 随着计算机网络技术和通信技术的飞速发展,教育正逐步走向信息化。高校各个部门都很重视信息化建设,然而由于传统的软件开发使用的平台、开发工具、操作系统在结构上的紧耦合,导致各个学校、各个部门之间的信息资源难以共享,因而形成了一个个“信息孤岛”。教育部推出的教育管理互操作框架规范(Education Management Information System Interoperability Framework,简称EMIF),规范的特点是在不需要改变现有系统基础上,采用区域集成服务器(ZIS)和客户端代理模式构建基于校园网的信息、共享和数据集成平台。本文在总结传统的解决方案的基础上,通过研究教育管理信息互操作框架规范,提出了基于SOA体系架构,采用WCF技术,构建教育信息系统互操作模型。并设计并开发EMIF区域中的核心组件—区域集成服务器(ZIS),并使之能够有效的与代理(Agent)及应用程序配合使用,实现教育管理信息系统之间的互操作。并着重研究了ZIS的Web服务的构建、报文安全通信服务,报文队列服务,报文转发服务,初步实现了一个分布式异构环境下数据共享和互操作平台的系统。系统实现了通过Web服务来实现互操作的报文传输,构建了通信模式从单一的访问方式到多种访问方式的高度灵活的系统。通过MSMQ消息队列所提供的稳定而灵活的异步交互机制很好的解决报文的稳定性,完成整个报文的处理和转发功能。采用了多线程机制来分别实现对消息队列的监听和转发,增强系统报文并发处理处理能力,提高了系统的效率。更多还原

【Abstract】 With the rapid development of the computer network technology and communication technology, education is gradually informationized. All the departments of Colleges pay more attention to Informatization Construction. However because the traditional software development platform, development tools, operating system the tightly coupled in the structure, it is difficult to share information resources among various schools and departments.So "information islands" comes into being.Ministry of Education launched the Education Management Interoperability Framework specification, referred to as EMIF.It uses Regional Integration Server (ZIS) and Client Agent model to build to build campus network information sharing and data integration platform without need to change the the existing system.Through summarizing the traditional soluntions this paper researched on education Management Information Interoperability Framework specification and proposed education information system interoperability model by WCF technology based on SOA architecture. This paper also designed and developed the core component of the EMIF region - Regional Integration Server (ZIS), and made it work effectively with the agent and applications to achieve interoperability between education management information systems. It focused on building Web services of the ZIS, security packet communications services, message queuing services, message forwarding service and realized data sharing and interoperability system under distributed heterogeneous environment. This System achieved interoperability of message transmission through Web services and built a communication mode from a single access method to access a wide range of highly flexible system. Through the more stable and flexible asynchronous interaction mechanism provided by the MSMQ message queue,this system sloved the message stability and completed the packet processing and forwarding. This system used Multi-threaded mechanisms to achieve the monitor and the transponders of the respective message queue, and enhance the concurrent process ablity of the message of the system and improved the efficiency of the system.更多还原
