In Django, models are Python classes that map directly to database tables using Django’s Object-Relational Mapping (ORM) system. Each model class represents a table, and each attribute within the class corresponds to a column in that table.
When you define a Django model by inheriting from django.db.models.Model, Django automatically creates a table name based on the model's app label and class name (e.g., appname_modelname), unless you specify a custom table name using the model’s Meta class with db_table.
Fields in the model (like CharField, IntegerField, DateTimeField, etc.) define the type of data the column will hold. Django maps each field to the appropriate column type in the database backend you’re using (like PostgreSQL, SQLite, or MySQL).
Django also automatically adds an id primary key field unless specified otherwise.
Once the model is defined, Django uses migrations to apply the structure to the database. Running makemigrations creates migration files, and migrate executes them, creating or updating tables accordingly.
In short, Django models abstract away SQL, letting you work with Python objects while still interacting with the underlying database efficiently.
