+``` + +--- + +## Key Points for Understanding + +### 1. Customer Perspective +- Customers just visit a URL (like any normal e-commerce site) +- They have no awareness it's a multi-tenant platform +- Each store looks completely separate and branded + +### 2. Vendor Perspective +- Vendors can use a subdomain (free/standard): `acme.wizamart.com` +- Or their own custom domain (premium): `store.acme-corp.com` +- Both routes go to the exact same backend code + +### 3. Developer Perspective +- The middleware layer detects which vendor is being accessed +- All business logic remains vendor-unaware +- Database queries automatically filtered by vendor +- No risk of data leakage because of multi-layer isolation + +### 4.
