# What is MongoDB ?
MongoDB is an open-source, NoSQL database that provides high performance, high availability & easy scalability. It is a document-oriented database.
# Some Basics
# Object-Oriented
This means, that the database stores data in JSON-like documents. These documents can vary in structure.
# NoSQL
MongoDB is classified as NoSQL database. This means, that it does not use the traditional rows & columns of relational databases.
- Instead, it uses collections and documents
These databases store data in flexible, schema-less formats: JSON, BSON documents. Even though, it is possible to write a schema-definition for a MongoDB database.
# MQL
MongoDB has its own query language, similar to SQL The MongoDB Query Language supports a wide range of queries, including CRUD operations, aggregation, geospatial queries.
