Hard-coded absolute paths make the script non-portable. Consider using relative paths or environment variables to make the script work across different development environments.

Hard-coded absolute path for the SQLite directory makes the script environment-specific. Use relative paths or path resolution based on the script's location.

Suggested change

	os.makedirs('/workspaces/code-society-25-2/lesson_25/db/db_app/src/main/resources/sqlite/', exist_ok=True)
	conn = sqlite3.connect('../db/db_app/src/main/resources/sqlite/data.db')
	# Resolve the SQLite directory relative to this script's location
	script_dir = os.path.dirname(os.path.abspath(__file__))
	sqlite_dir = os.path.join(script_dir, '../db/db_app/src/main/resources/sqlite/')
	os.makedirs(sqlite_dir, exist_ok=True)
	db_path = os.path.join(sqlite_dir, 'data.db')
	conn = sqlite3.connect(db_path)

Using itemId as the primary key could cause issues if the same item is checked out multiple times by different users or at different times. Consider using a composite key or a separate auto-generated ID field.
