Recommendation

SQL

SQL preserves database-native operations like transactions, DDL, and ordered seed replay in a way flat exports cannot.

CSV

Use CSV for tabular interchange where downstream loading rules are already defined.

Decision factors

Decision Factors

Facteurs de decision

Need for transactional replay versus flat data import.
Requirement to preserve schema changes, ordering, and rollback behavior.
Portability across toolchains versus database-native execution fidelity.
How often support or QA needs to inspect and diff the fixture by hand.

Erreurs courantes a eviter

Using CSV as the only seed artifact when ordered transactional replay is required.
Treating a large SQL fixture like a dummy blob instead of validating it against a real parser and database.
Skipping rollback rehearsal before promoting large seed loads into CI or staging.
