Welcome to MongoDB Docs
Welcome to the MongoDB documentation. This site contains everything you need to learn to effectively use MongoDB as an application developer or an operator.
What is MongoDB?
MongoDB is a document-oriented, operational database built from the ground up as an alternative to the relational database for modern applications.
Unlike relational databases, MongoDB allows developers to store rich JSON-like documents that map naturally to the objects they use in their code.
For example, to model user objects in an application, a relational model would require multiple tables for what could be elegantly stored in MongoDB as this:
{ firstname: "Bob", lastname: "Smith", email: "bob@smith.com", address: { street: "100 Main St", city: "Anytown", state: "MO", zip: "11111" } }
And retrieved with queries such as this:
users.find({address.zip : "11111"})
MongoDB also offers:
Strong consistency with ACID transactions.
Modern additional built-in query capabilities such as geo search, lexical search, and vector search.
Serverless horizontal scaling with geo-aware fault tolerance across all major clouds.
Security primitives that allow MongoDB to operate in the most demanding of enterprise environments.
