A project scope includes the collection, exchange and reporting of data from multiple systems. Conceptual, logical and physical data models are maintained. How many models of each type can be expected?
A.
More logical data models than physical data models, and more logical data models than conceptual data models
B.
The same number of each of the model types
C.
More conceptual data models than logical data models, and more logical data models than physical data models
D.
Only 1 conceptual data model, 1 logical data model and 1 physical data model
E.
More physical data models than logical data models, and more logical data models than conceptual data models
It's definitely E. There are multiple systems, so the physical models will be the most, then logical (break down into subject areas, etc), and then conceptual data models (high level)
Large projects typically have one conceptual model, multiple logical models, and fewer physical models
