3.1. MongoDB through the Ruby lens

Normally when you think of drivers, what come to mind are low-level bit manipulations and obtuse interfaces. Thankfully, the MongoDB language drivers are nothing like that; instead, they’ve been designed with intuitive, language-sensitive APIs, so that many applications can sanely use a MongoDB driver as the sole interface to the database. The driver APIs are also fairly consistent across languages, which means that developers can easily move between languages as needed. If you’re an application developer, you can expect to find yourself comfortable and productive with any of the MongoDB drivers without having to concern yourself with low-level implementation details.

In this first section, you’ll install the MongoDB Ruby driver, connect to the database, and learn how to perform basic CRUD operations. This will lay the groundwork for the application you’ll build at the end of the chapter.
