What is canonical data modelling?

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.

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.

What is Canonical design pattern?

Integration design pattern Canonical data model pattern

The canonical data model pattern is considered as the “oldest” integration design pattern. It refers to creating a messaging or data model that can be leveraged by consumers directly or indirectly.
