Centralized Version Control System

• Version control (Revision Control) is a system that records changes to a file or groups of files and directories over time, so that we can review or go back to specific versions. In addition to this it will allow multi user mode
• In Centralized System, any one who makes changes needs to given access to the central location (Central Repository)
• Once they have the access and the client software, the users can get the working copy, make changes, get latest changes etc…..
• For any reason if the central repository is down, all the developers will not be able to
  • make changes in connected centralized version control system
  • update/get changes in the disconnected centralized version control system
• To resolve this, we have version control adminstrators who configure
  • Primary and Standby Servers
• For any version control system, backups and archivals are important, Administrators configure this (Subversion Administrator, Clearcase Administrators)

Distributed Version Control System
