The following chapter deals with systems for workgroup computing focusing on the cooperation between people working in a team. Situations where several users synchronously perform a task obtain special attention, thus exploring the use of real-time applications. As an example for synchronous cooperation, we discuss architectural models for electronic meeting rooms.
Furthermore, we will investigate distributed document systems and we will provide an overview of existing group editors. Using the examples of Iris and DistEdit, we will introduce typical problem areas of group editors. The advantages of highly structured documents and logical document views for the handling of joint authoring scenarios and the management of shared documents will be demonstrated. Concepts for version and history management will be discussed. Finally, undo-operations in the context of group editors will be considered in detail.
