Each configuration item has a version number. Typically, the highest version number represents the current working design. Lower version numbers represent earlier designs. Each time a project member checks an item in, Rational Statemate assigns it a version number by incrementing the highest existing version number.
The Rational Statemate built-in CM tool tracks versions using whole numbers (positive integers). When you create a new item and check it into the databank, Rational Statemate assigns it a “1” version number. If a third-party CM tool uses a different system of version numbering, the version numbers displayed by Rational Statemate conform to the format of the third-party tool.
