Brief Version Control Systems (VCS) History
First Generation
- Concurrent Development was handled solely with locks. Only one person could be working on a file at a time.
- Networking not supported / One File at a Time operations
Examples : RCS, SCCS
Second Generation
- A bit more permissive about simultaneous modifications, with one notable restriction: Users must merge the current revisions into their work before they are allowed to commit.
- Centralized Networking / Multi-file operations
Examples : CVS, SourceSafe, Subversion, Team Foundation Server
Third Generation
- Separates merge and commit
- Distributed Networking / Changesets operations
Examples : GIT, Mercurial, Bazaar
Origins
- Linux Kernel Project
- Meant to be distributed, fast and more natural
- Capable of Handling Large Projects
