I described how you can define validation rules on a collection and how those rules validate document inserts and updates.

This article is part of Robert Sheldon's continuing series on Mongo DB. To see all of the items in the series, click here. Throughout this series, I’ve discussed various ways to work with the documents in a MongoDB collection. If you’ve been following along, you should now have a good sense of how to perform basic create, read, update, and delete (CRUD) operations. As you might recall, much of my focus has been on how to use MongoDB Shell to carry out these operations.
