Relationship notes

• A User can make zero or many donations.
• An Organization can receive zero or many donations.
• Donation currently stores organization and username as String values.
• OrganizationRegister is responsible for loading organizations from the external API.
• DonationRegister, UserDatabase, and DonationDatabase handle SQLite persistence concerns.
