Now your database does too. MongoDB is a document database, which means it stores data in JSON-like documents. We believe this is the most natural way to think about data, and is much more expressive and powerful than the traditional row/column model. { "_id": "5cf0029caff5056591b0ce7d", "firstname": "Jane", "lastname": "Wu", "address": { "street": "1 Circle Rd", "city": "Los Angeles", "state": "CA", "zip": "90404" }, "hobbies": ["surfing", "coding"] } Rich JSON Documents The most natural and productive way to work with data. Supports arrays and nested objects as values. Allows for flexible and dynamic schemas. > db.users.find({ "address.zip" : "90404" }) { "_id": "5cf0029caff5056591b0ce7d", "firstname": "Jane", "lastname": "Wu", "address":{}} { "_id": "507f1f77bcf86cd799439011", "firstname": "Jon", "lastname": "Davis", "address":{}} { "_id": "5349b4ddd2781d08c09890f3", "firstname": "Jim", "lastname": "White", "address":{}} { "_id": "5bf142459b72e12b2b1b2cd", "firstname": "Jeff", "lastname": "Taylor", "address":{}} { "_id": "5cf003283b23d04a40d5f88a", "firstname": "Jerry", "lastname": "Miller", "address":{}} { "_id": "5bf142459b72e12b2b1b2cd", "firstname": "Jai", "lastname": "Williams", "address":{}} { "_id": "5cf0036deaa1742dd225ea35", "firstname": "Jess", "lastname": "Johnson", "address":{}} { "_id": "54495ad94c934721ede76d90", "firstname": "Jill", "lastname": "Brown", "address":{}} { "_id": "566eb3c704c7b31facbb0007", "firstname": "Janet", "lastname": "Jones", "address":{}} { "_id": "5a999cc461d36489a27f2563", "firstname": "Jan", "lastname": "Smith", "address":{}} Powerful query language Rich and expressive query language that allows you to filter and sort by any field, no matter how nested it may be within a document. Support for aggregations and other modern use-cases such as geo-based search, graph search, and text search. Queries are themselves JSON, and thus easily composable. No more concatenating strings to dynamically generate SQL queries. session.start_transaction() order = { line_items : [ { item : 5, quantity: 6 } ] } db.orders.insertOne( order, session=session ); for x in order.line_items: db.inventory.update( { _id : x.item } , { $inc : { number : -1 * x.quantity } }, session=session ) session.commit_transaction() All the power of a relational database, and more... Full ACID transactions. Support for joins in queries. Two types of relationships instead of one: reference and embedded.
