It is great that you want to utilize the strong features of MongoDB. In a first step it might help to change the wording. As mentioned from @shrey_batra and @Lauren_Schaefer MongoDB models relations as well as other databases. Maybe we should say tabular vs. natural approach to store data and with them relations.
To get the most out of an noSQL Setup, you need to change the way of thinking about schema design. Your first goal will no longer be to get the maximal normalized Schema, Denormalization is not bad, the requirement of your queries will drive your design. The story will start to think about a good schema design. In case you move the SQL normalized Data Model 1:1 to MongoDB you will not have much fun or benefit.

Since you are new to MongoDB and noSQL I highly recommend to take some of great and free classes from the MongoDB Univerity:
Generally data modelling is a broad topic to discuss, this is due to many factors that may affect the design decision. One major factor is the application requirements, knowing how the application is going to interact with the database. With MongoDB flexible schema characteristic, developers can focus on the application design and let the database design conform for the benefit of the application. See also :

I’d recommend getting Professional Advice to plan a deployment There are many considerations, and an experienced consultant can provide better advice with a more holistic understanding of your requirements. Some decisions affecting scalability (such as shard key selection) are more difficult to course correct once you have a significant amount of production data.
