+# Database Setup Guide
+
+## Overview
+
+This guide helps you set up and troubleshoot database connectivity issues for the InPact AI Backend.
+
+## Quick Start
+
+### 1. Environment Variables
+
+Create a `.env` file in the `Backend` directory with the following variables:
+
+```env
+# PostgreSQL Database Credentials
+user=your_database_user
+password=your_database_password
+host=your_database_host
+port=5432
+dbname=your_database_name
+
+# Supabase (for REST API fallback)
+SUPABASE_URL=https://your-project.supabase.co
+SUPABASE_KEY=your_supabase_anon_key
+
+# AI Services
+GEMINI_API_KEY=your_gemini_api_key
+YOUTUBE_API_KEY=your_youtube_api_key
+
+# Optional: Connection Settings
+DB_POOL_SIZE=5
+DB_MAX_OVERFLOW=10
+DB_POOL_TIMEOUT=30
+DB_CONNECTION_TIMEOUT=10
+DB_MAX_RETRIES=3
+DB_RETRY_DELAY=1.0
+DB_PREFER_IPV4=true
+DB_SSL_MODE=require
+DB_USE_REST_FALLBACK=true
+```
+
+### 2. Supabase Setup
+
+If you're using Supabase:
+
+1. Go to [Supabase Dashboard](https://app.supabase.com/)
+2. Select your project
+3. Navigate to **Settings** → **Database**
+4. Copy the connection details:
+   - Host
+   - Port
+   - Database name
+   - User
+   - Password (use the password you set when creating the project)
+
+### 3. Create Required Tables
+
+Run the following SQL in your Supabase SQL Editor or pgAdmin:
+
+```sql
+-- Trending Niches Table
+CREATE TABLE IF NOT EXISTS trending_niches (
+    id SERIAL PRIMARY KEY,
+    name VARCHAR(255) NOT NULL,
+    insight TEXT,
+    global_activity INTEGER DEFAULT 1 CHECK (global_activity BETWEEN 1 AND 5),
+    fetched_at DATE NOT NULL,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Create index for faster queries
+CREATE INDEX idx_trending_niches_fetched_at ON trending_niches(fetched_at DESC);
+```
+
+## Common Issues and Solutions
+
+### Issue 1: IPv6 DNS Resolution Error
+
+**Error Message:**
+```
+❌ Connection attempt failed: getaddrinfo failed
+🔴 DNS/IPv6 RESOLUTION ERROR
+```
+
+**Root Cause:**
+- Supabase hosts resolve to IPv6-only addresses
+- Your local network/ISP doesn't support IPv6 properly
+- Windows network stack issues with IPv6
+
+**Solutions:**
+
+#### Option 1: Use Supabase Connection Pooler (Recommended)
+
+1. Go to Supabase Dashboard → **Database** → **Connection Pooler**
+2. Enable the connection pooler
+3. Use the pooler connection string (it's IPv4 compatible):
+   ```env
+   host=aws-0-us-east-1.pooler.supabase.com
+   port=6543
+   ```
+
+#### Option 2: Configure IPv4 DNS Servers
+
+1. Open Network Settings in Windows
+2. Change DNS servers to Google DNS:
+   - Primary: `8.8.8.8`
+   - Secondary: `8.8.4.4`
+
+#### Option 3: Use a VPN with IPv6 Support
+
+Use a VPN service that properly supports IPv6 connectivity.
+
+#### Option 4: REST API Fallback Mode
+
+The server will automatically use Supabase REST API as a fallback if PostgreSQL connection fails. Ensure you have set:
+```env
+SUPABASE_URL=https://your-project.supabase.co
+SUPABASE_KEY=your_anon_key
+DB_USE_REST_FALLBACK=true
+```
+
+### Issue 2: Missing Tables
+
+**Error Message:**
+```
+⚠️ 'trending_niches' table not found
+```
+
+**Solution:**
+
+Run the table creation SQL from section "3. Create Required Tables" above.
+
+### Issue 3: SSL Connection Issues
+
+**Error Message:**
+```
+SSL error: certificate verify failed
+```
+
+**Solution:**
+
+1. Update your `.env` file:
+   ```env
+   DB_SSL_MODE=require
+   ```
+
+2. Or disable SSL for local development (not recommended for production):
+   ```env
+   DB_SSL_MODE=disable
+   ```
+
+### Issue 4: Connection Timeout
+
+**Error Message:**
+```
+Connection timeout after X seconds
+```
+
+**Solutions:**
+
+1. Increase timeout in `.env`:
+   ```env
+   DB_CONNECTION_TIMEOUT=30
+   DB_POOL_TIMEOUT=60
+   ```
+
+2. Check your firewall settings
+3. Verify database host is reachable:
+   ```powershell
+   Test-NetConnection -ComputerName your-host.supabase.co -Port 5432
+   ```
+
+## Degraded Mode Operation
+
+If the database connection fails, the server will start in **degraded mode**:
+
+- ✅ Server starts successfully
+- ✅ Health check endpoints work
+- ⚠️ Database-dependent features are limited
+- ⚠️ Clear error messages for unavailable features
+
+## Health Check Endpoints
+
+### Basic Health Check
+```
+GET /
+```
+
+Response:
+```json
+{
+  "message": "Welcome to InPact AI API!",
+  "status": "healthy",
+  "database": {
+    "connected": true,
+    "has_fallback": true
+  },
+  "version": "1.0.0"
+}
+```
+
+### Detailed Health Check
+```
+GET /health
+```
+
+Response:
+```json
+{
+  "status": "healthy",
+  "database": {
+    "connected": true,
+    "error": null,
+    "has_fallback": true,
+    "config_valid": true
+  }
+}
+```
+
+## Testing Your Setup
+
+### 1. Start the Server
+
+```powershell
+cd Backend
+uvicorn app.main:app --reload
+```
+
+### 2. Check Server Logs
+
+Look for these messages:
+```
+✅ Database connected successfully!
+✅ Tables created successfully or already exist
+✅ trending_niches table found
+✅ Server Ready
+```
+
+### 3. Test Endpoints
+
+```powershell
+# Health check
+curl http://localhost:8000/
+
+# Trending niches
+curl http://localhost:8000/api/trending-niches
+```
+
+## Advanced Configuration
+
+### Connection Pool Settings
+
+For production environments, optimize connection pooling:
+
+```env
+DB_POOL_SIZE=20           # Number of connections in pool
+DB_MAX_OVERFLOW=40        # Additional connections allowed
+DB_POOL_TIMEOUT=30        # Seconds to wait for connection
+DB_POOL_RECYCLE=3600     # Recycle connections after 1 hour
+```
+
+### Retry Configuration
+
+Configure retry behavior for better resilience:
+
+```env
+DB_MAX_RETRIES=5          # Number of connection attempts
+DB_RETRY_DELAY=2.0        # Initial delay between retries (exponential backoff)
+```
+
+## Troubleshooting Commands
+
+### Check Network Connectivity
+
+```powershell
+# Test DNS resolution
+nslookup db.your-project.supabase.co
+
+# Test port connectivity
+Test-NetConnection -ComputerName db.your-project.supabase.co -Port 5432
+
+# Check IPv6 connectivity
+ping -6 db.your-project.supabase.co
+```
+
+### Database Connection Test
+
+```python
+# test_connection.py
+import asyncio
+import asyncpg
+
+async def test():
+    conn = await asyncpg.connect(
+        user='your_user',
+        password='your_password',
+        database='your_database',
+        host='your_host',
+        port=5432,
+        ssl='require'
+    )
+    result = await conn.fetchval('SELECT 1')
+    print(f"Connection successful! Result: {result}")
+    await conn.close()
+
+asyncio.run(test())
+```
+
+## Support
+
+If you continue to experience issues:
+
+1. Check the server logs for detailed error messages
+2. Verify all environment variables are set correctly
+3. Test database connectivity using the commands above
+4. Review the [Supabase documentation](https://supabase.com/docs/guides/database)
+
+## Production Deployment
+
+For production deployments:
+
+1. ✅ Use connection pooler
+2. ✅ Enable connection health checks (`pool_pre_ping=True`)
+3. ✅ Set appropriate timeouts
+4. ✅ Configure proper SSL/TLS
+5. ✅ Set up monitoring and alerts
+6. ✅ Use connection pooling
+7. ✅ Enable REST API fallback
+8. ✅ Test failover scenarios
