# WARNING: Using SQLite on Hugging Face Spaces will result in data loss on every restart.
# Consider using a persistent database like PostgreSQL for production deployments.

# OPTIONAL: To implement data backup, you can add the following instructions:
# 1. Save the database file to a persistent storage (e.g., Hugging Face Hub or cloud storage) before the Space restarts.
# 2. Restore the database file on startup.
