Is using inheritance in Django ORM a suitable approach for database modeling?

Using inheritance in Django ORM for database modeling is possible and sometimes convenient, but it is not always the optimal solution.

Django supports several types of model inheritance:

• Abstract base classes: used for common fields and methods, do not create a separate table in the database.
• Multi-table inheritance: each model in the hierarchy creates its own table linked by a foreign key.
• Proxy models: change the behavior of a model without altering the database structure.

Problems with inheritance in ORM:

• Multi-table inheritance can lead to complex JOIN queries and decreased performance.
• Sometimes it is simpler and more efficient to use explicit relations (ForeignKey, OneToOneField) instead of inheritance.

It is recommended to use inheritance when it truly reflects the domain and simplifies the code, but for complex database schemas, it is better to design models with explicit relations and avoid excessive inheritance.
