EAI集成平台的设计和在三峡船舶调度中的应用

Design of integrated platform of EAI and its application in ship scheduler

首先对EAI(Enterprise Application Integration)的原理进行了介绍.根据集成内容的划分粒度,提出了一种按照用户交互、数据集成、应用连接、业务流程整合和外部集成这5个层次进行构建EAI集成平台的方法,并分析每一层次的作用及其所需技术.然后介绍该集成平台的总体结构.最后以一个实际例子,从用户交互、数据集成和应用连接这三个层次演示了采用该集成平台的EAI在三峡船舶调度中的实际效果,验证了这种结构的松散耦合和高可扩展性的优点.

The principles of enterprise application integration （EAI） were discussed and its characters were described by contrasting to traditional integrated method. The method to build the platform of EAI was proposed, in which the integrated platform for EAI was constructed from five layers, user interface（UI）, data integration（DI）, application to application（A2A）, business process management （BPM） and outer integration（such as B2B, B2C）. The functions and the technologies of each layer was analyzed, and the general framework of this platform was introduced. The application of ship scheduler in three gorges was demonstrated as an actual case in the layer of UI, DI and A2A. The result shows this platform is characterized by the features of high elexihility and loose coupling.
