Mongo DB Basics
In MongoDB Basics, you will learn the essentials of the MongoDB document model and explore the advantages of writing software using a database that accommodates the ways developers commonly think about and structure data in their applications. MongoDB stores data using a binary form of JSON (JavaScript Object Notation), enabling you to work with data in the same way you would work with JSON in your programming language of choice.
