Introduction to MongoDB data modeling review

“

- Congratulations. In this unit, you learned about the basics of data modeling, including the purpose of data modeling, types of relationships among data, specifically one-to-one, one-to-many, and many-to-many; embedded and referenced documents, the effects of document, collection, and database sizes, 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. Reference relationships store data by including references in one document to another document. There's 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. Now that you have a general understanding of data modeling, you might want to learn more about tools provided by MongoDB that help you improve your schema.
