Microsoft offers Microsoft Dynamics 365 in two different editions: the business and enterprise edition. Besides containing the extended enterprise edition Microsoft Flow, it also contains the Common Data Model.
Consistent user experience and seamless integration
The Common Data Model from Microsoft consists of a universal database of entities such as projects, customers, campaigns used by all Microsoft Dynamics 365 applications as well as Office 365 to exchange information. This allows you to have any app on the same data and use it. You can easily add entities and use analytics capabilities across all applications.
By using the Common Data Model to integrate applications you will be able to provide a consistent user experience for your employees.
