What should I use if I care about transactions more than schema flexibility?

If you care about transactions more than schema flexibility, you should generally use a relational database — for example:
- PostgreSQL
- MySQL
- SQLite for smaller/local use cases
Why: relational databases give you strong ACID transactions, consistency, and reliable constraints. That makes them a better fit when correctness matters more than being able to change document structure freely.
If you want, I can also compare this choice against MongoDB or other NoSQL options.
