Beginners MongoDB Guide along with Mongoose + Mongo Atlas

MongoDB is a  NOSQL database, cross-platform, document oriented database that provides, high performance, high availability, and easy scalability. MongoDB works on concept of collection and document.

Any relational database has a typical schema design that shows number of tables and the relationship between these tables. While in MongoDB, there is no concept of relationship.

Advantages of MongoDB over RDBMS

1. Schema less − MongoDB is a document database in which one collection holds different documents.
2. No complex joins.
3. Deep query-ability. MongoDB supports dynamic queries using a document-based query language that’s nearly as powerful as SQL.
4. Ease of scale-out − MongoDB is easy to scale.
5. Conversion/mapping of application objects to database objects not needed.
6. Uses internal memory for storing the (windowed) working set, enabling faster access of data.

Why Use MongoDB?

1. Document Oriented Storage − Data is stored in the form of JSON style documents.
2. Index on any attribute
3. Replication and high availability
4. Rich queries
5. Fast in-place updates
6. Professional support by MongoDB
