The To-Do application uses a SQLite database for storing information. The database has four tables:

1. projects
2. todo_items
3. people
4. people_todo

Projects can have many todo_items and any number of people can be linked with any number of todo_items through the people_todo table.

You will find the to-do.sqlite database file in the ./components/ folder in the tutorials distribution. The to-do TEMPLATE.sqlite file serves as a backup if you need an empty database to start with.
