IBM Rational ClearCase
The Rational ClearCase family consists of several software tools for supporting software configuration management (SCM) of source code and other software development assets. It is developed by the Rational Software division of IBM. ClearCase forms the base for configuration management for many large and medium sized businesses and can handle projects with hundreds or thousands of developers.
A part of Rational ClearCase is revision control system, which is a feature for end users.
ClearCase supports two kinds of use models, UCM (Unified Change Management), and base ClearCase. UCM provides an out-of-the-box model while base ClearCase provides a basic infrastructure (upon which UCM is built). Both can be configured to support a wide variety of needs. UCM is part of RUP (Rational Unified Process) and therefore all process templates and roles can be used from RUP.
ClearCase can run on a number of platforms including AIX, z/OS, Linux, HP-UX, Solaris, and Windows. It can handle large binary files, large numbers of files, and large repository sizes. It handles branching, labeling, and versioning of directories.

Famous quotes containing the word rational:
“We must not suppose that, because a man is a rational animal, he will, therefore, always act rationally; or, because he has such or such a predominant passion, that he will act invariably and consequentially in pursuit of it. No, we are complicated machines; and though we have one main spring that gives motion to the whole, we have an infinity of little wheels, which, in their turns, retard, precipitate, and sometime stop that motion.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
