How to implement polymorphism in MongoDB?

Question

There seems to be concepts of implementing polymorphism with MongoDB but I can't find any good documentation on how to do it.

Can I do this as part of MongoDB itself - or do I have to model it in Mongoose ( I use Nodejs )

To give an example of the type of data I want to store/ retrieve, I want to store 2 types of products in a product collection. Simple and Grouped.

Both types will have

• _id
• sku
• name

Grouped products will have

• associated_ids an array of id's to link to simple products
• meta_name
• meta_description

Simple Products will have

• buy_price
• sell_price

Is there a good data modelling program for MongoDB as well?

If someone can point me in the right direction, I don't think I am looking in the right place.

Thanks Martin

Example of usage MongoDb Polymorphism here .

You may find out course "Data Modeling" of MongoDb University helpful. There are lectures "Schema Versioning Pattern" and "Polymorphic Pattern" gives some steps of modeling polymorphism in MongoDb.
