There are 3 modules in this course

This course will teach you how to perform data analysis using MongoDB's powerful Aggregation Framework.

You'll begin this course by building a foundation of essential aggregation knowledge. By understanding these features of the Aggregation Framework you will learn how to ask complex questions of your data. This will lay the groundwork for the remainder of the course where you'll dive deep and learn about schema design, relational data migrations, and machine learning with MongoDB. By the end of this course you'll understand how to best use MongoDB and its Aggregation Framework in your own data science workflow.

In this module you'll learn the fundamentals of MongoDB's Aggregation Framework. This will cover basics like filtering and sorting, as well as how to transform array data, how to group documents together, how to join data, and how to traverse graph data.

The course was excellent, but there were some problems: - There were mistakes in some assignments codes. - Some codes mentioned in the lectures were not available in resources.

Reviewed on Sep 9, 2019

Very clear introduction to the MongoDB Aggregation Framework. Interesting and comprehensive data analysis examples as well!

Reviewed on Sep 14, 2025

This is a great course, but more corrections on the solutions in the graded-assignment section and discussion-forum participations by the staff should be considered.
