Overview of this book

MongoDB is one of the most popular database technologies for handling large collections of data. This book will help MongoDB beginners develop the knowledge and skills to create databases and process data efficiently. Unlike other MongoDB books, MongoDB Fundamentals dives into cloud computing from the very start – showing you how to get started with Atlas in the first chapter. You will discover how to modify existing data, add new data into a database, and handle complex queries by creating aggregation pipelines. As you progress, you'll learn about the MongoDB replication architecture and configure a simple cluster. You will also get to grips with user authentication, as well as techniques for backing up and restoring data. Finally, you'll perform data visualization using MongoDB Charts. You will work on realistic projects that are presented as bitesize exercises and activities, allowing you to challenge yourself in an enjoyable and attainable way. Many of these mini-projects are based around a movie database case study, while the last chapter acts as a final project where you will use MongoDB to solve a real-world problem based on a bike-sharing app. By the end of this book, you'll have the skills and confidence to process large volumes of data and tackle your own projects using MongoDB.

Preface

Summary

We started this chapter with a detailed study of the structure of MongoDB queries and how different they are from SQL queries. Then, we implemented these queries to find and count the documents and limit the number of fields returned in the result using various examples. We also learned about the various conditional and logical operators and practiced using them in combination to notice the difference in results.

We then learned how to provide a text pattern using regular expressions to filter our search results, and covered how to query arrays and nested objects and include their specific fields in the results. Finally, we learned how to paginate large result sets by using limiting, sorting, and skipping on the documents in the result.

In the next chapter, we will learn how to insert, update, and delete documents from MongoDB collections.
