Transform MongoDB Data

# Introduction

In this lab, you will learn how to transform MongoDB data using basic aggregation operations. The lab covers five key steps: selecting output fields, renaming fields, calculating new fields, formatting output, and filtering results. Through these steps, you will gain hands-on experience in reshaping and analyzing data stored in MongoDB collections. The lab provides a sample dataset of books and demonstrates how to leverage the aggregation pipeline to extract, manipulate, and present the data in a more meaningful way.
