When a new document is created on a MongoDB collection, an ID gets assigned to it to make it unique to that collection, and inside the document, multiple fields can be defined where the value could be a variant of data types ranging from arrays, strings, integers, objects and so on. Unlike relational tables, collections are self-contained, this makes them much easier to work with. It allows data that is frequently accessed together by an application to be stored in the same place and makes database reading easy and fast. A BSON is a document, with no need for a predefined data schema. MongoDB is the most popular and most advanced document-based database, where all data is stored in Binary JSON (JavaScript Object Notation) known as BSON. You can download the longest stable version (LTS) and install on your local machine from its Official Download Page. Note: To follow along, you will need to install Node.js.
