Tools used in CVCS and DVCS
CVCS tools: Subversion (SVN): A widely-used system with simple branching and tagging, suitable for small to medium projects. CVS (Concurrent Versions System): One of the older systems, now outdated but still used for some smaller projects. Perforce Helix Core: A robust tool for managing large codebases with advanced security and integration options. DVCS tools: Git: The most popular DVCS, known for its speed, branching capabilities, and integration with platforms like GitHub. Mercurial: Simpler than Git, with an easy-to-use interface and strong support for branching. Bazaar: A flexible tool that can work in both centralized and distributed modes. Fossil: A unique system with built-in project management features like bug tracking and wikis.
