+# Database Demo Data
+
+This directory contains comprehensive demo data for the bakery inventory system.
+
+## Files
+
+### `demo_inventory_data.sql`
+Complete demo dataset that creates a realistic bakery inventory scenario. This file includes:
+
+**Demo Configuration:**
+- Tenant ID: `c464fb3e-7af2-46e6-9e43-85318f34199a`
+- Demo User: `demo@panaderiasanpablo.com`
+- Bakery: "Panadería San Pablo - Demo"
+
+**What's Included:**
+
+1. **Raw Ingredients (16 items):**
+   - Flours (Wheat, Whole wheat)
+   - Yeasts (Fresh, Dry active)
+   - Fats (Butter, Olive oil)
+   - Dairy & Eggs (Milk, Fresh eggs)
+   - Sugars (White, Brown)
+   - Seasonings (Salt, Chocolate, Vanilla, Cinnamon)
+   - Nuts & Fruits (Walnuts, Raisins)
+
+2. **Finished Products (8 items):**
+   - Croissants (with par-baked and fully-baked stages)
+   - Breads (Whole wheat, Toasted)
+   - Pastries (Napolitanas, Palmeras, Magdalenas)
+   - Other products (Empanadas, Coffee with milk)
+
+3. **Stock Lots with Diverse Scenarios:**
+   - **Good Stock**: Normal levels, fresh products
+   - **Low Stock**: Below threshold items (Yeast, Butter, Coffee)
+   - **Critical Stock**: Items needing immediate attention
+   - **Out of Stock**: Completely sold out (Napolitanas)
+   - **Expired Stock**: Items past expiration date (Some eggs)
+   - **Expires Soon**: Items expiring today/tomorrow (Milk, some croissants)
+   - **Overstock**: Items with excess inventory (Sugar, Salt)
+
+4. **Production Stages:**
+   - `raw_ingredient`: Base materials
+   - `par_baked`: Semi-finished products from central bakery
+   - `fully_baked`: Ready-to-sell products
+
+5. **Stock Movements History:**
+   - **Purchases**: Raw material deliveries
+   - **Production Use**: Materials consumed in production
+   - **Transformations**: Par-baked to fully-baked conversions
+   - **Sales**: Customer purchases
+   - **Waste**: Expired/damaged products
+   - **Reservations**: Items reserved for specific orders
+
+## Usage
+
+### Run the Demo Data Script
+
+```sql
+-- Connect to your PostgreSQL database
+\i shared/database/demo_inventory_data.sql
+```
+
+### Expected Results
+
+The script will create:
+- **24 ingredients** (16 raw + 8 finished products)
+- **25+ stock lots** with different scenarios
+- **15+ stock movements** showing transaction history
+- **Summary reports** showing inventory status
+
+### Demo Scenarios Included
+
+1. **Critical Alerts Testing:**
+   - Expired eggs (past expiration date)
+   - Low stock yeast (below 1.0kg threshold)
+   - Milk expiring today
+   - Out of stock napolitanas
+
+2. **Production Workflow:**
+   - Par-baked croissants ready for final baking
+   - Fresh products baked this morning
+   - Reserved stock for afternoon production
+
+3. **Sales Patterns:**
+   - Popular items sold out (napolitanas)
+   - Steady sales of bread and pastries
+   - Morning rush reflected in stock levels
+
+4. **Inventory Management:**
+   - Multiple batches with different expiration dates
+   - FIFO rotation scenarios
+   - Waste tracking for expired items
+
+
+## Customization
+
+To modify the demo for different scenarios, edit the variables at the top of `demo_inventory_data.sql`:
+
+```sql
+-- Demo Configuration Variables
+demo_tenant_id UUID := 'your-tenant-id'::UUID;
+demo_user_email VARCHAR := 'your-demo-email@domain.com';
+demo_bakery_name VARCHAR := 'Your Bakery Name';
+```
+
+## Testing Scenarios
+
+The demo data is designed to test all major inventory features:
+
+- ✅ Stock level calculations
+- ✅ Expiration date tracking
+- ✅ Low stock alerts
+- ✅ Out of stock handling
+- ✅ Multi-batch inventory
+- ✅ Production stage tracking
+- ✅ Movement history
+- ✅ Waste management
+- ✅ Reserved stock
+- ✅ Cost calculations
+- ✅ Storage location tracking
+- ✅ Quality status monitoring
+
+Perfect for demos, development, and testing!
