What is MongoDB?

"MongoDB is a document database, which means it stores data in JSON-like documents." - Official MongoDB Website MongoDB is one of the most popular NoSQL databases.

What are the advantages of NoSQL?

  • Scalability: by default, non-relational databases are split (or "shared") across many systems instead of only one. This makes it easier to improve performance at a lower cost.
  • Flexibility: new datasets and properties can be added to a document without the need to make a new table for that data.
  • Replication: copies of the database run in parallel so if one goes down, one of the copies becomes the new primary data source. FreeCodeCamp
