Techopedia Explains Canonical Data Model

A canonical data model primarily enables an organization to create and distribute a common definition of its entire data unit. The design of a CDM requires identifying all entities, their attributes and the relationships between them.

The importance of a CDM is particularly evident in integration processes where data units are shared between different information system platforms. It utilizes a generalized data format to present/define data that makes it simple to share data among multiple applications.
