- **Query the data:**
Use a MongoDB shell or driver (e.g., Python's PyMongo) to connect to the MongoDB server. You may need to provide your username and password:
// Using the MongoDB shell mongo -u your_username -p // Using PyMongo (Python) from pymongo import MongoClient client = MongoClient('mongodb://your_username:your_password@your_host:your_port')
Databases are created automatically in MongoDB when you start inserting data into a collection. You don't need to explicitly create them.
Use the
createCollection
method to create a new collection. Collections are similar to tables in relational databases but can store documents with varying structures.
// Using the MongoDB shell use my_database db.createCollection('my_collection') // Using PyMongo (Python) db = client['my_database'] db.create_collection('my_collection')
Use the
insertOne
method to add a document to the collection. Documents are JSON-like structures that store data in key-value pairs.
// Using the MongoDB shell db.my_collection.insertOne({ 'name': 'John Doe', 'email': 'john.doe@example.com', 'age': 30 }) // Using PyMongo (Python) db.my_collection.insert_one({ 'name': 'John Doe', 'email': 'john.doe@example.com', 'age': 30 })
Use the
find
method to retrieve documents from the collection.
// Using the MongoDB shell db.my_collection.find() // Using PyMongo (Python) for doc in db.my_collection.find(): print(doc)
