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.

Introduction to JSON

JSON is a full-text, lightweight format for data representation and transportation. JavaScript's simple representation of objects gave birth to JSON. Douglas Crockford, who was one of the developers of the JavaScript language, came up with the proposal for the JSON specification that defines the grammar and data types for the JSON syntax.

The JSON specification became a standard in 2013. If you have been developing applications for a while, you might have seen the transition of applications from XML to JSON. JSON offers a human-readable, plain-text way of representing data. In comparison to XML, where information is wrapped inside tags, and lots of tags make it look bulky, JSON offers a compact and natural format where you can easily focus on the information.

To read or write information in JSON or XML format, the programming languages use their respective parsers. As XML documents are bound by schema definitions and tag library definitions...
