摘要
分析了虚拟企业信息系统的需求 ,提出了基于B/W /D与Internet机制的VEIS体系结构 ,阐述了VEIS的设计与实现问题。这种构件化的信息系统可以使面向用户的各个应用系统通过统一的软件总线协议访问业务处理服务器。通过应用数据层、工作流处理层以及规则和协议组成的知识库等三层结构 。
The requirement of VEIS (Virtual Enterprise Information System) is analyzed, an Internet based VEIS architecture in B/W/D (Browser/Web server/Database server) mode is presented, and the design and implementation of VEIS is discussed. The information system is composed of components, and permits each user oriented application to access transaction server by the uniform software bus protocols. A three level architecture, composed of application data level, workflow handling level and knowledge database with rules and protocols, is deployed to represent and manage the information in VEIS.
