Although data and process models depict the same system with different views, systemi designers must synchronize these different views to make sure that their models are consistent and complete. One way to ensure this is through a data-to-process-(RUD matrix. Select a system with which you are familiar Identify at least three of the entities used in that system and their attributes. Nest, identify the processes associated with those entities, Then build a data-to-process-CRUD matrix, using Figure 9.30 as your template As a quality check; show your matrix to someone else who is familiar with the system, and have her of him review it for completeness and correctness.
