The term version control or version management describes a system used for detecting changes made to documents or files. For every change made to a document a new version of said document gets stored in a designated archive (with time stamp and user ID). Older versions of a document can be accessed via version control and, through logging, every change can be tracked.
Version management systems coordinate common access of multiple users to the files. Therefore, they are often used in software development or in Content Management Systems. Version control of documents in conjunction with Document Control postulated by DIN EN ISO 9001 - and the workflows based thereon - also play an important role. bitfarm-Archiv implements version control functions with the help of the open-source software setting SVN (SubVerSion).
