A Cooperative Database System based on Workspace Hierarchy
نویسندگان
چکیده
Cooperative work enables a users group to collaborate in the same project. The use of a cooperative database system enables distributed users to cooperate on large data volumes. We modelize the cooperative work by alternative versions which belong to each participant, and a merge mechanism which is controled by a group supervisor. This model is a variant of the distributed architecture model, called the Workspace Model. This model proposes a distributed virtual memory of objects, in a hierarchy of servers and clients. We have developed the WEA system, which implements this model.
