What is canonical data modeling?

Defining a Canonical Data Model (CDM)

CDMs are a type of data model that aims to present data entities and relationships in the simplest possible form to integrate processes across various systems and databases.

What are the 4 different types of data models?

What are the types of data modeling? The three primary data model types are relational, dimensional, and entity-relationship (E-R). There are also several others that are not in general use, including hierarchical, network, object-oriented, and multi-value.

When would you use a canonical data model?

A canonical data model (CDM) is a type of data model that presents data entities and relationships in the simplest possible form. It is generally used in system/database integration processes where data is exchanged between different systems, regardless of the technology used.

What is canonical model in API?

A canonical model is a design pattern used to communicate between different data formats. Essentially: create a data model which is a superset of all the others ("canonical"), and create a "translator" module or layer to/from which all existing modules exchange data with other modules.
