The ability to leverage a common data model that can be used for multiple applications is invaluable. This avoids data duplicity and creates a core component that multiple business units can leverage. Microsoft via the common data model is allowing applications such as PowerApps, Flow, Power BI, Dynamics and Azure to leverage the common data model.
The Common Data Model metadata is enabling consistency of data across numerous applications and processes, which store data conforming with the CDM.
In addition to the metadata system, the Common Data Model includes a set of standardized, extensible data schemas that Microsoft and its partners have published. This collection of predefined schemas includes entities, attributes, semantic metadata, and relationships. The schemas represent commonly used concepts and activities, such as Account and Campaign, to simplify the creation, aggregation, and analysis of data.
