MongoDB Fundamentals

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

Database Access

MongoDB databases deployed on the Atlas Cloud have several security features enabled by default, such as user access control. Database access control verifies user authentication credentials, such as the username and password. Therefore, even if network access is available from anywhere, you will still need to authenticate before successfully connecting to the MongoDB database in the cloud. This is necessary to protect databases deployed in the cloud from unauthorized access over the internet. More importantly, when compared with other security features, access control cannot be disabled for cloud databases and will always remain enabled.

Database access covers the following aspects of database security:

  • Database users
  • Database roles

When compared with other MongoDB installations, the management of user accounts in the Atlas Cloud is configured at the project level. Users created in one Atlas project are shared among all MongoDB database clusters...
