To implement a module which interacts with the database to:

Register new users
Adding new RSS feeds
- Check if feed exists
- If not, inserting new
- Linking the user to the feed if not linked before
Deleting RSS feed for user
- Remove link to the user
- Or remove link and feed if user is the last subscriber for this feed
- Use COUNT() on the linking table?
Getting feed list for update
Getting user's feeds
Getting feed content from last update (items)
Storing feed content from the update (delete last + insert new)

Recommendations:

Use SQLite for MVP

@Miroslavsckaya, let's use SQLite in MVP to save time.
I'll create another ticket for PostgreSQL migration.

@Miroslavsckaya we also need to have migrations to be able to properly develop the project as a team. So I've created #16 for you. You can implement that after imlementing a draft of this task.

We forgot about get_user() method. So we should implement it too 🤷‍♂️
