FAQ

Questions about erd templates

What entities are essential in a referral application database schema?

Core entities typically include users (referrers and referees), referral codes, referral events, reward rules, and status history. Depending on the scenario, you may add hiring pipeline stages, insurance policy details, or healthcare provider credentials.

How do I model the referrer-referee relationship in an ERD?

Use a many-to-many relationship between users and referral codes, or a direct referrer_id foreign key on the referral record. The ERD should distinguish the person who shares the code from the person who signs up.

Can I use one referral schema for customer, employee, and partner programs?

Yes, but you'll likely need extension tables. Customer referrals focus on rewards; employee referrals add job applications and hiring stages; partner or multi-level referrals require parent-agent hierarchies and commission splits.

How do I handle referral status tracking in an ERD?

Add a referral_status table linked to the referral event with a timestamp and status value (e.g., invited, applied, converted, rewarded). This supports audit trails and analytics.
