【摘要】：信息爆炸时代已经来临,企业规模不断增大,工作量也随之增加,传统的集中式系统已经不能满足企业的要求,系统中一旦中央处理机无法承担工作负载,或者产生一些故障,将会造成整个系统的瘫痪,给企业带来不可估量的损失。分布式系统有效的解决了这一问题,通过增加系统节点的方式,把工作分配到其他节点上,有效的提高了系统的可靠性。随着分布式系统的广泛使用,分布式系统各组件间如何通信以进行数据的交互已成为研究的焦点。中间件技术的日益成熟,各系统之间的通信可交由中间件来承担,分布式系统中的组件通过将中间件集成到系统中,利用数据分发模型,实现了子系统间数据分发的服务,达到了分布式系统通信的要求。本文在现有数据分发模型的基础上,提出了将Web Service作为一种数据分发模型进行数据的分发,并结合企业的办公业务需求,采用了消息队列和Web Service两种中间件方式向外部系统提供数据分发服务。具体内容包括阐述数据分发服务的概念与应用,提出多种数据分发模型,比较各模型之间的优缺点以及应用场景,分析系统的业务逻辑需求,设计系统的各个功能模块,对每个功能模块的具体实现给予说明,最后对系统的可靠性和实用性进行测试,测试结果表明该系统通过采用消息队列模型和Web Service分发模型可以有效的对外提供数据分发服务。
[Abstract]:The era of information explosion has come, the scale of enterprises has been increasing, the workload has also increased, the traditional centralized system can no longer meet the requirements of enterprises, once the central processor can not bear the workload, or produce some faults. Will cause the paralysis of the whole system, bring immeasurable loss to the enterprise. Distributed system solves this problem effectively, by adding system nodes, the work is assigned to other nodes, and the reliability of the system is improved effectively. With the wide use of distributed systems, how to communicate among the components of distributed systems to interact with each other has become the focus of research. With the maturity of middleware technology, the communication between different systems can be carried out by middleware. The components of distributed system can realize the service of data distribution among subsystems by integrating middleware into the system and using the data distribution model. It meets the requirement of distributed system communication. On the basis of the existing data distribution model, this paper proposes to use Web Service as a data distribution model to distribute data, and combine with the office business requirements of the enterprise. Message queue and Web Service middleware are used to provide data distribution services to external systems. The concrete contents include: explaining the concept and application of data distribution service, putting forward a variety of data distribution models, comparing the advantages and disadvantages of each model and the application scenario, analyzing the business logic requirements of the system, designing each function module of the system. Finally, the reliability and practicability of the system are tested. The test results show that the system can effectively provide data distribution services by using message queue model and Web Service distribution model.
