mongodbMongoDB query example

MongoDB is a document-oriented NoSQL database used for high volume data storage. It is an open-source database that uses a document-oriented data model, which means data is stored in JSON-like documents with dynamic schemas.

Below is an example of a MongoDB query that finds all documents in the collection "users" where the "age" field is greater than or equal to 18:

db.users.find({ age: { $gte: 18 } })

The output of this query would be a list of documents in the "users" collection where the "age" field is greater than or equal to 18.

Code explanation

• db.users: This is the collection that the query is searching in.
• find(): This is the method used to search the collection.
• { age: { $gte: 18 } }: This is the query condition, which specifies that the documents returned must have an "age" field greater than or equal to 18.
