一种基于分层模型的企业应用集成方案

Method of EAI based on hierarchical layered model

分析了当前企业应用集成面临的问题,提出了利用分层模型将应用先划分为小粒度的组件再横向耦合的解决思路。将当前企业应用所需的集成功能归纳为界面集成、资产集成、复用集成、流程集成和信息集成五类,并指出在横向分层模型设计时为能满足上述五类集成应遵循平台化、流程化、统一化三大原则。给出了一种基于分层模型的企业应用集成方案,介绍了该方案在银行应用集成上的实践成果及下一步的应用设想。

In this paper the problems encountered in the current EAI are analyzed and a solution which utilizes a layered modeling to decompose the application into small-sized components, followed by a horizontal coupling, is also introduced in details. Based on this solution, the integration functions required by the current enterprise application are categorized into five sectors which include interface integration, asset integration, multiplex integration, process integration and information integration. Furthermore, in order to meet the requirements of the above five categories of integration during designing the horizontally layered model, at least three principles of platformization, process streamlining and unification should be applied, which are also well demonstrated in this paper. In the last section, a method of the EAI based on a layered modeling is summarized and its practical achievements applied in the EAI of banking IT system is introduced, as well as its future outlook.
