Summary
We began this chapter by covering the fundamentals of data, databases, RDBMS, and NoSQL databases. You learned the differences between RDBMS and NoSQL databases, and how to decide which database is a good fit for a given scenario. You learned that MongoDB can be used as self-managed or as DbaaS, set up your account in MongoDB Atlas, and reviewed MongoDB deployment on different cloud platforms and how to estimate its cost. We concluded the chapter with the MongoDB structure and its basic components, such as databases, collections, and documents. In the next chapter, you will utilize these concepts to explore MongoDB components and its data model.
