AB  - This study formalizes schema and Version Evolution Operations (VEO), creation and management of multiple versions capable of simulating various alternative business scenarios. Also versioning-algebra (V-algebra) to handle VEO’s is also proposed in this study. It is expected that system developed based on proposed solution will not only keep multiple versions but also provide easy way of investigating various versions.
