2. What is NoSQL Database

Before starting MongoDB Tutorial, we must know about NoSQL. NoSQL or “non-SQL” a non-structured database. It provides a facility for storage and retrieval of data using fields. While in SQL the data stores in a tabular form. Companies are using NoSQL database in big data and real-time applications. NoSQL offers “eventual consistency” so that it may not meet the real-time application requirements. Still, its use to merits over relational databases.

iv. Indexing

Any document can index with primary and secondary indices.

v. Replication

It has this powerful tool. Every document has one primary node which further has two or more secondary replications.

vi. Aggregation

For efficient usability, MongoDB has aggregation framework for batch processing.

vii. GridFS

It has grid file system, so it can use to store files in multiple machines.

viii. Sharding

For the larger data sets sharding is the best feature. It distributes larger data to multiple machines.
