SCM

Git is a free & open source, distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Every Git clone is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server. Branching and merging are fast and easy to do

ADempiere is an industry strength solution that combines ERP, CRM and SCM support for business processes. As opposed to the so called "World Class" ERP solutions, ADempiere (originally based on Compiere®) was designed for the globalized world. While the current incumbent World Class ERP's had to build layers on top of the core product in order to provide support for multiple languages, currencies, companies, etc., ADempiere had them embedded from the original design.

CVS is the Concurrent Versions System, the dominant open-source network-transparent version control system. CVS is useful for everyone from individual developers to large, distributed teams:

Its client-server access method lets developers access the latest code from anywhere there's an Internet connection.
Its unreserved check-out model to version control avoids artificial conflicts common with the exclusive check-out model.
Its client tools are available on most platforms.
