Centralized Version Control Systems (CVCS)

• CVS, or Concurrent Versions System.
• Apache Subversion (aka. SVN).
• Perforce.
• Rational Clear-Case (IBM) (Configuration Management).

• Central server holds everything (good/bad).
• Easier administration, better control.
• Limited or no off-line work.
• Single point of failure.
• Branching is easy in some cases (Subversion).
• Merging is still a pain.
