Final answer:
A model in Rails is a class that represents a database table and is used to interact with the database and perform operations on data.
Step-by-step explanation:
A model in Rails refers to a class that represents a database table. It is used to interact with the database and perform operations such as retrieving, creating, updating, and deleting records.
In Rails, models are used to define the structure and behavior of data. They provide an object-oriented interface to work with the application's data.
For example, if you have a model called User, it would correspond to a table named users in the database. The model would have attributes that represent the columns in the table, and you can define methods in the model to perform operations on the data.
