In configuration management (CM), one has to control (among other things) changes made to software and documentation. This is called revision control, which manages multiple versions of the same unit of information. Although revision control is important to CM, it is not equal to it.
Synchronization Models, also known as Configuration Management Models, describe methods to enable revision control through allowing simultaneous, concurrent changes to individual files.
In revision control, changesets are a way to group a number of modifications that are relevant to each other in one atomic package, that may be cancelled or propagated as needed.
