SQL mi yoksa NoSQL mi tercih edilmeli hangi durumlarda?

Depends on what you're building, but here’s the quick way I break it down: For most fintech projects where money moves, you'll want SQL. ACID guarantees matter when ledgers and transactions are involved—the last thing you need is a partial debit that never commits or twice-charged withdrawals. PostgreSQL with its JSONB column has been my go-to: schema for critical paths, flexibility for logs or metadata without denormalizing everything. NoSQL only makes sense when your data is truly unstructured or you’re scaling writes horizontally. I used MongoDB once for a KYC pipeline that ingested 50+ file formats with varying schemas; defining schema on read saved us weeks of migrations. But once that data hit reporting or audit, it all got pumped into SQL anyway—so the hybrid path is often the real play.
