SYSTEM AND METHOD FOR CONTROLLED, MULTI-TIERED SUBSETTING OF A DATA MODEL

The present invention is a data processing system and method for providing controlled, multi-tiered checkout of a subset of a first data model storage (111) to a second data model storage (111). The present invention include a checkout module (107) responsive to a user checkout request and a first protection level associated with the first data model storage (111) for generating a subset of the first data model storage (111), for generating a second protection level associated with the subset, for updating the first protection level in accordance with the second protection level, and for updating a second data model storage (111) with the subset and the second protection level associated with the subset. The present invention also includes a data manager (108) for managing the subsetted data in accordance with the second protection level. Also included in the present invention is an update module (109) responsive to an update request for updating the first data model storage (111), using a transactions data storage (113), in accordance with the modifications made to the subsetted data using the data manager (108).
