MongoDB Explained: Database, Collections & Documents | NoSQL Basics
In MongoDB, a database is a logical container for data.
It groups together collections, similar to how a relational database groups tables.
Each database has its own set of collections and documents.
A collection in MongoDB is like a table in relational databases.
It’s a grouping of documents.
Collections do not enforce a schema (they are schema-less), meaning documents inside the same collection can have different structures.
The basic unit of data in MongoDB.
Stored in BSON (Binary JSON) format.
Similar to a row in relational databases, but more flexible.
