Research And Application Of SOI Based On ESB

This paper analyzes the pushing factors of EAI from micro and macro attitudes, and the developing process of EAI (Enterprise Application Integration) solution. Then explains why SOI (Service-Oriented Integration), this new EAI architecture, is better than the integration techniques before.Based on the CRM (Customer Relationship Management)/ERP (Enterprise Resource Plan) Business Integration Project, the whole paper discusses how to use ESB (Enterprise Service Bus) to implement SOI. The main contents of this paper includes:1. Analyzing the developing process of SOI, implementation methods and critical techniques used.2. Using Object-Oriented method to do requirement analysis, designing and implementation of CRM/ERP Business Integration Project. Describing how to implement SOI by using the ESB infrastructure in detail, and researching the working mechanism of ESB.3. Summarizing the CRM/ERP Business Integration Project, experiences are concluded below: providing a universal and tight SOI architecture template, and introducing each layer thoroughly; uniform right management should be imported into EAI as early as possible; how to decide the granularity of business service; using ESB as the break point to implement SOI; how to make best use of Open Source projects for EAI.
