Database Schema Designer
Use when the user asks to create ERD diagrams, normalize database schemas, design table relationships, or plan schema migrations.
Before & after
Same prompt, same agent — the only difference is the skill.
A database schema for a podcast platform would need to handle users, episodes, subscriptions, and that kind of thing. Normalization is important so you don't have data redundancy. You'll probably want separate tables for different entities and then think about relationships between them. There are different approaches you could take depending on how you want to query the data.
PODCAST PLATFORM SCHEMA TABLE: users • id (PK) • email (unique) • role (creator | listener) • created_at TABLE: shows • id (PK) • creator_id (FK→users) • title • description • cover_url • created_at TABLE: episodes • id (PK) • show_id (FK→shows) • title • description • audio_url • duration_seconds • published_at • created_at TABLE: subscriptions • id (PK) • listener_id (FK→users) • show_id (FK→shows) • subscribed_at • (composite index: listener_id, show_id) TABLE: listens • id (PK) • listener_id (FK→users) • episode_id (FK→episodes) • position_seconds • completed_at (nullable) • created_at KEY RELATIONSHIPS • One creator has many shows • One show has many episodes • Listeners subscribe to shows • Listeners generate listen records per episode INDEXES: (show_id, published_at), (listener_id, subscribed_at)
