A collaboration object can be bound to another collaboration object to form a collaboration group. A collaboration group harnesses the power of multiple discrete collaborations to integrate related business processes.
The relationships between collaborations in a collaboration group are restricted only by the fact that one collaboration supplies business objects to the other. Collaboration groups can be connected in any number of topologies, such as chains or even webs.
Collaboration groups are also useful for providing data isolation. For details, see the Collaboration Development Guide.
