{'key1':'value1', 'key2': 'value2' }

The data for the demonstration is stored for into sqlite, which is distributed with python by default. The project has following files:
- pntdata.py: This script creates the test database and fills it with dummy data.
- pntdata.db: The sqlite database file created by pntdata.py
