What is Models?

Models are Ruby classes that represent data and business logic. They interact with the database to perform CRUD (Create, Read, Update, Delete) operations on the data. Models provide a structured way to manage data, enforce validations, and define relationships between different data entities within an application. They are a core component of the Model-View-Controller (MVC) architectural pattern.
