Welcome to The MongoDB Docs

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:

{
   first name: "Bob"
   lastname: "Smith"
   email: "bob@smith.com"
   address: {
      street: "100 Main St"
      city: "Anytown"
      state: "MO"
      zip: "11111"
   }
}

Which you can retrieve 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.
