How much database abstraction do I need?
summary
Explains concrete tradeoffs: uses Doctrine ORM for type-safe CRUD and rapid forms, falls back to DBAL or native C extensions when performance or features demand it, demonstrates the N+1 query trap and a streaming import fix (flush+clear every 100 rows) that avoids terabyte memory spikes, shows schema diffs driving Doctrine Migrations, and lists removed items in DBAL4/ORM3 plus practical migration tools like Rector.
