Managing change sets
The change set is the fundamental unit of change in Engineering Workflow Management source control. The contents of any workspace, component, or stream is expressed as a collection of change sets. The collection begins with the one that was created when the initial set of projects was checked in. A change set can include changes to the contents of individual files and changes to a component namespace (such as delete, rename, and move operations). A small change set might modify a few lines in a single file. A large one can include changes to the contents of many files, changes to file names, folder names, and folder contents. By grouping related changes and then applying them as a unit to a workspace or stream, Engineering Workflow Management source control ensures that such groups of changes are made together or not at all.
