MongoDB

MongoDB is a source-available cross-platform document-oriented database program. It has a great GUI tool named Mongodb Compass which makes it easy to create, read, update, and delete data.

NoSQL

Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.

Code Example

Inserting and querying documents in MongoDB:

db.users.insertOne({
    name: "Alice",

    skills: ["JavaScript", "React"]
});

// Find users older than 25
db.users.find({ age: { $gt: 25 } });
