How Python Data Engineers Use Django ORM

Data engineers building Django-based data applications use the ORM to query and write pipeline results to a relational database without writing raw SQL. Django's QuerySet API lets engineers filter and aggregate records in Python, and the migration system ensures database schema stays in sync with model definitions across environments.
