Hello all.
I have a question for the design of a canonical data model. The issue is that I want to create a data services layer, and for making the design of services that expose data, first I want to create the canonical data model, which allows me to properly design services, and I want to know if this canonical data model should correspond to the data model of the database, E / R model , or I just model the information concepts that are handled in the database.
