🚧 What needs to be done

With the MVP data model decided by the team in #178 we now want to go ahead and implement this model so that the application can make use of it.

1. SQL scripts are written based on data model in docs: Refiner data model v0 proposal #178
2. SQL scripts are applied to DB
3. App code is updated as needed
4. Seeding script is updated as needed
5. Tests are updated as needed

🤔 Why it needs to be done

This implementation will represent the initial version (or close to it) of the data model used by users in the MVP. The backend functionality we plan to implement in the near future heavily relies upon this work being completed.

🏗️ Acceptance Criteria

See requirements above.

⚙️ Technical Notes

We do not necessarily need to consider future migrations as a part of this ticket.
