协同设计环境下的虚拟企业信息系统

摘要

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 sof t ware-bus protocols. A three-level architecture, composed of application data l ev el, workflow handling level and knowledge database with rules and protocols, is deployed to represent and manage the information in VEIS.%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，表达和管理VEIS中的信息。
