Schema Design and References in MongoDB

Welcome to the MongoDB Video Series and in this video, I'm talking about how we can reference collections within mongodb. Even though mongodb is schema less, sometimes it a good idea to have loosely defined schema, and if we have repetitive data in the collection it may be good idea to separate the same and make it available in totally different collection. In this video, I've explained the scenario with an appropriate example which will help you to understand how to make use of the collection reference. You'll also understand the basics of aggregation framework in MongoDB in this video using $lookup.
