Object-Relational Mapping — a programming technique that lets you interact with a database using objects and methods instead of raw SQL.
ORMs like Django ORM, SQLAlchemy, and Prisma map database tables to classes, rows to objects, and columns to attributes. They handle query generation, type conversion, relationship loading, and SQL injection prevention. Trade-offs include performance overhead and the 'N+1 query problem.'
Using Django's ORM to query glossary terms: GlossaryTerm.objects.filter(category__slug='ai-ml', is_featured=True) instead of writing raw SQL.
ORMs dramatically accelerate development by abstracting SQL, preventing injection vulnerabilities, and making code portable across database backends.
