The key takeaway is that with Mongodb, it is JSON objects in, and JSON objects out of the database. MongoDB is free and open-source and scales well for almost any project.
You are simply working with objects, and they have persistence via Mongodb. This makes the data more seamless and easier to work with. The document model in Mongodb maps to the objects in the application code. This is quite different than how traditional relational databases work such as MySQL.
MongoDB is a database system that stores data in flexible, JSON based documents, which means fields can vary from document to document and data structures can be changed over time.
