Similar to the Repeated Data Models method, a single model is used to manage the logical and physical data design. The information removal action blocks (Delete, Disassociate and Transfer) are maintained in this model. Project models only contain the data required to support the project and reference the information removal action blocks from the master data model rather than implement them.
By isolating the logical and physical data models as well as the action blocks that call triggers, the Referential Integrity (RI) logic maintains its integrity. Using a master and partial view data model allows the model size to be more manageable. Since changes are controlled through the master and partial view data model, model management is simplified.
Some manual procedures are required to ensure that the RI triggers and information removal action blocks are available to other projects. Like the Repeated Data Model method, model size is more manageable as model management becomes more complex. Unlike the Repeated Data Model method, each project model only contains the data definitions it requires from the master data model.
