We covered an introduction to MongoDB in the first chapter. Recall that MongoDB is a document-oriented database program, also classified as a NoSQL database, and it uses JSON-like documents with schemas. In this book, MongoDB Atlas, which was highlighted briefly in the previous chapter as one of the database-as-a -service offerings by MongoDB for addressing the affordability challenges of small-scale start-ups and independent developers, will be used. First, we will set up an account on MongoDB and then set up MongoDB servers, known as clusters, to connect to applications. Finally, we will employ default (native) database drivers and a third-party driver to have the database connect with to Node application. We will also create database schemas and data models.
If you have an existing MongoDB account, you can use your credentials to log in to the MongoDB Atlas dashboard. If you don't, then you can sign up for free at https://www.MongoDB.com/cloud/atlas....
