ClearCase is Rational's market-leading solution for software configuration management system. ClearCase is a powerful system for managing versions of files and directories, generally refers to as elements. Virtually any project artifact can be stored in ClearCase repository called Versioned Object Base or simply VOB. One unique feature of ClearCase is the ability to version directory elements. This capability proved to be invaluable for code restructuring which commonly occurs during development and new releases.
ClearCase provides a rich set of access methods and controls to its repositories. All element access must go through a view. A view specifies a configuration, or config_spec, for selecting elements within a VOB. ClearCase tightly integrates with the underlying operating system to track changes and control access. The ClearCase administrator is the most powerful user having full control of a site installation. On Unix, this would be the superuser, UID=0, on the VOB server. On Windows, it is any user who is a member of the clearcase domain group.
