Drop an Index > db.user.dropIndex('name.given_1') In the following program, we created a collection. When a document is inserted for the first time into the new collection, the mongo collection is created. Note that by default, collections always have an index on the _id field, for easy document retrieval by primary key, so any additional indexes will be listed after that. To create a MongoDB Collection using PyMongo, use the new collection name as index to the database reference and insert a document to the collection.

Unique indexes allow you to ensure that there is at most one record in the collection with a given value for that field – very useful with things like email addresses! See Indexes on a Collection > db.user.getIndexes() You'll get an overview of the differences between SQL and NoSQL, and you'll also.

A good rule of thumb for structuring data in MongoDB is to prefer embedding data inside documents to breaking it apart into separate collections, unless you have a good reason (like needing to store unbounded lists of items, or needing to look up objects directly without retrieving a parent document). In this step-by-step tutorial, you'll learn how to use Python to interface with the NoSQL database system MongoDB. Perhaps the most powerful feature of document databases is the ability to nest objects inside of documents. Below are just a few of the ways you can structure your documents. MongoDB documents are formatted in BSON (an extended Binary form of JSON), which allows you ultimate flexibility in structuring data of all types. Don’t hesitate to go over to the official documentation for more in-depth discussions of all of these topics. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Whether you’re just firing up your first MongoDB Atlas cluster, or you’re a long-time veteran user, we put together our best set of useful examples to refresh your knowledge or help you get your bearings. MongoDB is the document database designed to make it easy for developers to work with data in any form, and from any programming language.
