Learn to retrieve exactly the data you need from MongoDB. This course will teach you how to write precise queries using filters, projections, sorting, and pagination - essential skills for any analyst working with document-based data.
What you'll learn
Writing queries in MongoDB can be confusing - especially when dealing with flexible schemas, nested fields, or arrays. For analysts coming from structured SQL environments, even basic filtering or projection can feel unfamiliar and error-prone. In this course, Query Data in MongoDB, you’ll gain the ability to write precise, effective queries that return exactly the data you need. First, you’ll explore how to filter documents using equality, comparison, logical, and nested conditions. Next, you’ll discover how to control the shape of your results using projection, including how to include, exclude, and target nested fields. Finally, you’ll learn how to sort, paginate, and combine query techniques to solve common real-world data analysis problems, like pulling top results or querying across time windows. When you’re finished with this course, you’ll have the skills and knowledge of MongoDB query fundamentals needed to retrieve, shape, and refine data with confidence in both Compass and Shell.
