A computer-based system creates a data object by preparing a data structure for the data object in a database and processes the data object at different processing stages each associating a different workflow state with the data object. The system can take and store automatically a snapshot of the data object, prior to a workflow transition of the data object from a first workflow state to a second workflow state, respectively associated with the snapshot and with the data object. The system also creates a unique locating reference for the snapshot based on a unique locating reference created previously for the data object. When the unique locating reference for the data object is received, controlled access to the data object and the snapshot is provided. Based on one unique locating reference, multiple states of the data object can be easily and efficiently made available concurrently to a user.
