DVCS

Distributed Version Control System

Code is stored in several repositories (often geographically dispersed). Can be modeled to be similar to the centralized model.

Advantages:

  • Built-in disaster recovery / redundancy

  • Works 'offline'

  • Fast: interaction with the repository is done locally.

  • Handles branching and merging well.

  • Supports 'ad-hoc' collaboration; as each developer can pull / push / etc. directly from each other's repositories (if network permits).

  • Flexible: can be used in a wide variety of code release work-flows.

Disadvantages:

  • Can become confusing...too flexible?

Examples:

  • git

  • Mercurial
