# mongodb
|
|
|
|
MongoDB is an open-source document database that provides high performance, high availability, and automatic scaling.
|
|
MongoDB obviates the need for an Object Relational Mapping (ORM) to facilitate development.
|
|
MongoDB stores documents in collections. Collections are analogous to tables in relational databases.
|
|
Unlike a table, however, a collection does not require its documents to have the same schema.
|
|
In MongoDB, documents stored in a collection must have a unique _id field that acts as a primary key.
