Summary
Microsoft helps make it easier for partners and customers to create new use cases and workflows without needing to redefine the healthcare data architecture.

The healthcare data model is included in Microsoft Cloud for Healthcare solutions. It's also available as a standalone option for partners and Dataverse customers in the Microsoft Cloud Solution Center.
