+## Database
+
+![ERD](./docs/erd.svg)
+
+De databasevisualisatie wordt gegenereerd uit `prisma/schema.prisma` via `prisma-erd-generator`.
+
+Handmatige generatie:
+
+```bash
+npm run db:erd
+```
+
+Tijdens lokale development draait `npm run dev` naast Next.js ook `npm run db:erd:watch`. Bij wijzigingen in `prisma/schema.prisma` wordt `docs/erd.svg` automatisch opnieuw gegenereerd.
+
+Gebruik `npx prisma db push` alleen om het schema naar de database te synchroniseren. Gebruik `npm run db:erd` om Prisma Client en de ERD te genereren.
 
 De app draait standaard op `http://localhost:3000`.

+## Prisma generators
+
+`prisma/schema.prisma` bevat twee generators:
+
+```prisma
+generator client {
+  provider = "prisma-client-js"
+}
+
+generator erd {
+  provider = "prisma-erd-generator"
+  output   = "../docs/erd.svg"
+}
+```
+
+`prisma generate` bouwt dus twee artifacts:
+
+- Prisma Client in `node_modules/@prisma/client`
+- het ERD-diagram in `docs/erd.svg`
+
+## Commands
+
+| Command | Gebruik |
+|---|---|
+| `npx prisma db push` | Schema synchroniseren naar de database |
+| `npx prisma db seed` | Seeddata laden |
+| `npm run db:erd` | `prisma generate`: Prisma Client en `docs/erd.svg` genereren |
+| `npm run db:erd:watch` | `prisma/schema.prisma` watchen en ERD opnieuw genereren |
+| `npm run dev` | Next.js dev server plus ERD watcher starten |
+
+Belangrijk: `db push` schrijft naar de database, maar genereert geen ERD. Gebruik na schemawijzigingen `npm run db:erd` of laat `npm run dev` de watcher draaien.
