What database does MS Dynamics 365 use to store its entities and records? Does CRM use its own database?

Question

What database does MS Dynamics 365 use to store its entities and records?
Default entities like Accounts, Contacts, etc. as well as customized ones.
Is it SQL Server or does CRM use its own custom database?
I didn't find much information anywhere regarding where exactly this data is being stored.

Is the database different for online vs on-premise?

I have been asked this question three times now and I just say it has its own database; and then I regret saying it.

Hi,

Dynamics 365 is currently not supported in the Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products (more to be added later on).

You can ask the experts in the dedicated Dynamics 365 forum over here:

Dynamics 365 uses the Common Data Service to store its data - see https://learn.microsoft.com/en-us/powerapps/maker/common-data-service/data-platform-intro

The Common Data Service abstracts the application from how the data is stored. In actual fact, the Common Data Service uses a mixture of Azure SQL, Azure Blob, and zure Data Lake.

For on-premise, it uses SQL Server
