## 1. What is a Model in Django?

**Answer**

A Django Model is a Python class that represents a table in the database. Each Model attribute corresponds to a column in the table. Django uses ORM (Object-Relational Mapping) to automatically translate operations on Python objects into SQL queries, allowing database manipulation without writing SQL directly.

## 2. Which base class should be used to create a Django Model?

**Answer**

All Django Models must inherit from django.db.models.Model. This base class provides all the necessary functionality to interact with the database: table creation, queries, saving, deletion, etc. Without this inheritance, the class would not be recognized as a Model by Django.

## 3. Which field type should be used to store a string with a limited length?

**Answer**

CharField is used to store short to medium strings with a maximum length defined via max_length. This parameter is required for CharField. For longer texts without size limits, TextField should be used instead as it has no length restriction.
