MongoDB is a free and open-source cross-platform document-oriented database program. It is classified as a NoSQL database program, meaning that it does not use the traditional SQL relational database management system.
Instead, MongoDB stores data in flexible, JSON-like documents called BSON (Binary JSON), which means that the fields in a document can vary from one document to another. This makes MongoDB particularly well-suited for storing large amounts of unstructured data, such as images, video, and audio.
MongoDB is designed to be scalable, fast, and easy to use. It uses a distributed database system, which means that it can store data across multiple servers, making it easy to scale as the size of the data grows. It also has a flexible schema, which means that the structure of the data can change over time.
MongoDB is often used in modern web applications to store data, and it is supported by many popular programming languages, including JavaScript, Python, and Java.
Here is an example of how to connect to a MongoDB database and insert a document using the MongoDB driver for Node.js:
const MongoClient = require('mongodb').MongoClient;
const uri = "mongodb+srv://<username>:<password>@cluster0.mongodb.net/test?retryWrites=true&w=majority";
const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(err => {
const collection = client.db("test").collection("devices");
// perform actions on the collection object
collection.insertOne({ name: 'My Device' }, function(err, result) {
console.log(result);
client.close();
});
});
