中小企业弹性ERP系统架构的设计

A design of flexible ERP system architecture for small or medium enterprises

针对中小企业发展特点和对企业资源计划(Enterprise Resource Planning,ERP)系统的特殊需求,提出一种层次型弹性ERP系统架构。该架构包括用户界面层、业务表示层、业务逻辑层、数据持久层四个层次。通过在各层次中进一步划分子层或模块的方式,可使对系统的弹性要求得以满足。结合开源软件OpenbravoERP可完成该构架的实现和测试。实验证明该架构具有适应性强、可裁剪和易扩展的优点,以该架构为基础的应用系统能够较好的满足中小企业实际需要。

Considering the particularities of small or medium enterprises＇ development and their requirements for the ERP systems,a flexible hierarchical ERP architecture is proposed.There are four layers in this architecture.They are GUI（Graphical User Interface） layer,business presentation layer,business logic layer,and data persistence layer.Within each layer,there are some other sub-layers and modules to meet the requirements of flexibility.The implementation and test can be done with open source software OpenbravoERP.The testing results show that the architecture is easy to transplant,to reduce and to expend.The system based on this architecture meets well the need of a small or medium enterprise.
