MongoDB CRUD Operations: Insert and Find Documents
Learn how to create, find, and query MongoDB documents in the mongo shell.
MongoDB CRUD: Insert and Find
Unit Overview
In this unit, you will be introduced to CRUD operations in MongoDB by inserting and finding documents. Inserting and finding documents will help you discover the ease and usability of MongoDB. You'll also build your own queries that use comparison and logical operators. Using operators will make your queries more precise and, in turn, make your application easier to develop. Finally, you'll learn how to query elements in an array. Arrays are a crucial data type that you will encounter frequently, so it's important that you have a solid understanding of how to work with them.

Hi there and welcome! In this unit, you’ll learn how to insert and find documents in MongoDB.
I’m Julie Gauthier. I’m a Curriculum Engineer at MongoDB, and I’ll be working with you through this unit.
Creating and reading data are fundamental operations of any database. MongoDB makes it easy to create queries to insert and find data quickly.
In this unit, we’ll first explain how to insert a document into a database by using the insertOne() and insertMany() methods.
Next, we’ll use the find() method to retrieve documents from a collection in the database.
Then, we’ll build queries with comparison and logical operators.
Finally, we’ll use $elemMatch to query array elements..
The most effective way to learn a new skill is to apply it in a real-world scenario. So, we’ve set up integrated development environments with lab activities for you to practice as you work through the unit.
Before beginning this unit, you should have a basic understanding of the document model and how to connect to MongoDB.
If you’re new to these topics, we recommend first checking out their respective units, and then returning to this one.
If you’re ready, let’s get started!
