为了避免企业信息系统外部和内部信息之间出现信息孤岛,将Web2.0和SOA的思想结合起来,提出了一个4层次的集成框架.该框架包括:数据层、服务层、展示层和协作层.其中展示层扮演了一个关键角色,它负责将外部信息从协作层聚集到信息系统中,也将系统内部信息从服务层扩散给公共用户.该框架用来描述外部用户如何对企业信息系统产生贡献和新的服务,以及企业web服务如何集成起来与用户进行协作.
In order to avoid information islands between the external and internal information systems of the enterprise information system, combining the ideas of Web2.0 and SOA, a four-level integration framework is proposed. The framework includes: data layer, service layer, presentation layer, and collaboration layer. The presentation layer plays a key role. It is responsible for the aggregation of external information from the collaboration layer into the information system and the dissemination of system internal information from the service layer to the public users. This framework is used to describe how external users generate information for the enterprise information system. Contributions and new services, and how enterprise web services integrate to collaborate with users.
