Dot Notation (Reaching into Objects) - MongoDB
MongoDB is designed for store JSON-style objects. The database understands the structure of these objects and can reach into them to evaluate query expressions. Let's suppose we have some objects of the form: > db.persons.findOne() { name: "Joe", address: { city: "San Francisco", state: "CA" } , likes: [ 'scuba', 'math', 'literature' ] }
