:: Version, source code and document control

Just as the general information of a business is valuable, so is all of the information related to software projects. Source code, design documents, project management documents, and many other types of information must be protected and stored in a manner that preserves the state of the project at any point in time. Version control systems also control access to sensitive and critical information using individual and roll-based access rights. Also, these systems prevent overwrites of information by allowing only one individual to work on an item at a time. Most of version control systems use a check-in/check-out system with the ability to rollback changes.
