And some helpful tools that can assist you in validating and managing your schema.

Embedded documents capture relationships among data by storing related data in a single document.

Referenced relationships store data by including references in one document to another document.

There is a lot of nuance to data modeling and schema design. If this topic interests you, check out some of our reference materials linked to this unit.
