Unlike the conceptual data modeling phase, where a few attributes may be shown for illustration purposes only, all of the attributes for each entity must be included during logical data modeling.

While conceptual and logical data modeling may result in two separate yet related data models, more often, these are two sequential phases of analysis acting upon the same data model.

Conceptual data modeling drives the initial broad specification within the canonical data model, and logical data modeling adds further detail within that same model.
