ActiveRecord is a Ruby library that serves as an object-relational mapping (ORM) tool. ORMs allow us to use a language other than SQL to perform CRUD operations on our data. ActiveRecord translates Ruby code into SQL and also creates Ruby objects from database rows.

ActiveRecord is a part of Rails and is used in the model layer. It allows us to use Ruby to manipulate objects without worrying about how those objects are persisted.
