From the perspective of the client computer, a ClearCase view appears to be just another file system. New files and directories created in a ClearCase view are referred as "view-private" to indicate that they are specific to the view and not version-controlled. This feature allows build systems to operate on the same file system structure as the source code and ensures that each developer can build independently of one other. At any time, a view-private object can be added to source control and become a versioned object, rendering it visible to other users.
