NoSQL and MongoDB

NoSQL

A NoSQL database is different than a relational database. NoSQL is a flexible database that can be stored without any scheme. Like a relational database, it does not store data in tables, relationships, or different features.

Types of NoSQL

There are four major types of NoSQL:

• Document databases
• Key-value databases
• Wide-column stores
• Graph databases

Advantages of NoSQL

There are some advantages of NoSQL:

• It does not have any predefined schema and can be changed dynamically.
• The queries in NoSQL are faster than the SQL database queries, as it stores unstructured data.
• NoSQL is a very flexible database that can be adjusted easily in any environment.
