Extra activity! Do it if you have extra time or are following along at home. It won't be covered during the hands-on lab.

Now we want to remove some unncessary id fields from the operations collection. We have bookId and userId but we also have these values in the embedded book and user fields.

• On the MongoDB diagram view, click the operations collection.
• On the relational mappings list on the right, click on the edit icon of opperations New Documents mapping rule.
• Uncheck the bookId and userId fields, and leave all other fields checked.
• Click Save and close.
