Make a backup of the database before editing its schema or contents. Inspect table definitions, use filtered previews for large tables, and test an SQL statement before saving changes. Close competing writers when appropriate and confirm that exported CSV files preserve identifiers, encodings, and date representations as intended.
This is best suited to working directly with local SQLite database files. Before committing a larger project, account for these trade-offs: focused on SQLite rather than many engines; concurrent file access requires care.
