Abstract
A dynamic versioning system for synchronizing different versions of modules among different versions of a complex multi-module software system, and maintaining a consistent view of a version of the complex system for each user having access to the system. The dynamic versioning system grants a user read-only access to the multiple modules in a complex system, and promotes the access to write access only when a user is ready to save a modified module in the permanent non-volatile memory of the complex system. The dynamic versioning system manages the evolving versions of the complex system with a Dynamic Versioning Table (DVT) and master modules that identify the multiple slave modules associated with a particular version of the complex system. Old versions of modules are removed from the complex system's permanent non-volatile memory when the last user has terminated use of the complex system.
