Summary
MongoDB is a simple yet powerful database. It abstracts away many of the more complicated implementation details so that you can focus on building applications. It's easy to get started with and offers a powerful, idiomatic developer experience that allows you to interact with the database, exclusively in the programming language of your choice, via your IDE.
The rest of the book details how powerful and flexible MongoDB is, the new features in MongoDB 7.0, and how you can use it to your advantage. Besides being a great database for web applications, transactional data, flexible schemas, and high-performance workloads, it is also a great database for learning through hands-on experience and building proofs of concept.
In the next chapter, you'll see how replication and sharding can help increase reliability and availability for your applications.
