+# Agentic RAG Database Integration
+
+## Overview
+
+This document describes the comprehensive database integration for the agentic RAG system, including session management, performance tracking, analytics, and quality metrics persistence.
+
+## Architecture
+
+### Database Schema
+
+The agentic RAG system uses the following database tables:
+
+#### Core Tables
+- `agentic_rag_sessions` - Main session tracking
+- `agent_executions` - Individual agent execution steps
+- `processing_quality_metrics` - Quality assessment metrics
+
+#### Performance & Analytics Tables
+- `performance_metrics` - Performance tracking data
+- `session_events` - Session-level audit trail
+- `execution_events` - Execution-level audit trail
+
+### Key Features
+
+1. **Atomic Transactions** - All database operations use transactions for data consistency
+2. **Performance Tracking** - Comprehensive metrics for processing time, API calls, and costs
+3. **Quality Metrics** - Automated quality assessment and scoring
+4. **Analytics** - Historical data analysis and reporting
+5. **Health Monitoring** - Real-time system health status
+6. **Audit Trail** - Complete event logging for debugging and compliance
+
+## Usage
+
+### Basic Session Management
+
+```typescript
+import { agenticRAGDatabaseService } from './services/agenticRAGDatabaseService';
+
+// Create a new session
+const session = await agenticRAGDatabaseService.createSessionWithTransaction(
+  'document-id-123',
+  'user-id-456',
+  'agentic_rag'
+);
+
+// Update session with performance metrics
+await agenticRAGDatabaseService.updateSessionWithMetrics(
+  session.id,
+  {
+    status: 'completed',
+    completedAgents: 6,
+    overallValidationScore: 0.92
+  },
+  {
+    processingTime: 45000,
+    apiCalls: 12,
+    cost: 0.85
+  }
+);
+```
+
+### Agent Execution Tracking
+
+```typescript
+// Create agent execution
+const execution = await agenticRAGDatabaseService.createExecutionWithTransaction(
+  session.id,
+  'document_understanding',
+  { text: 'Document content...' }
+);
+
+// Update execution with results
+await agenticRAGDatabaseService.updateExecutionWithTransaction(
+  execution.id,
+  {
+    status: 'completed',
+    outputData: { analysis: 'Analysis result...' },
+    processingTimeMs: 5000,
+    validationResult: true
+  }
+);
+```
+
+### Quality Metrics Persistence
+
+```typescript
+const qualityMetrics = [
+  {
+    documentId: 'doc-123',
+    sessionId: session.id,
+    metricType: 'completeness',
+    metricValue: 0.85,
+    metricDetails: { score: 0.85, missingFields: ['field1'] }
+  },
+  {
+    documentId: 'doc-123',
+    sessionId: session.id,
+    metricType: 'accuracy',
+    metricValue: 0.92,
+    metricDetails: { score: 0.92, issues: [] }
+  }
+];
+
+await agenticRAGDatabaseService.saveQualityMetricsWithTransaction(
+  session.id,
+  qualityMetrics
+);
+```
+
+### Analytics and Reporting
+
+```typescript
+// Get session metrics
+const sessionMetrics = await agenticRAGDatabaseService.getSessionMetrics(sessionId);
+
+// Generate performance report
+const startDate = new Date('2024-01-01');
+const endDate = new Date('2024-01-31');
+const performanceReport = await agenticRAGDatabaseService.generatePerformanceReport(
+  startDate,
+  endDate
+);
+
+// Get health status
+const healthStatus = await agenticRAGDatabaseService.getHealthStatus();
+
+// Get analytics data
+const analyticsData = await agenticRAGDatabaseService.getAnalyticsData(30); // Last 30 days
+```
+
+## Performance Considerations
+
+### Database Indexes
+
+The system includes optimized indexes for common query patterns:
+
+```sql
+-- Session queries
+CREATE INDEX idx_agentic_rag_sessions_document_id ON agentic_rag_sessions(document_id);
+CREATE INDEX idx_agentic_rag_sessions_user_id ON agentic_rag_sessions(user_id);
+CREATE INDEX idx_agentic_rag_sessions_status ON agentic_rag_sessions(status);
+CREATE INDEX idx_agentic_rag_sessions_created_at ON agentic_rag_sessions(created_at);
+
+-- Execution queries
+CREATE INDEX idx_agent_executions_session_id ON agent_executions(session_id);
+CREATE INDEX idx_agent_executions_agent_name ON agent_executions(agent_name);
+CREATE INDEX idx_agent_executions_status ON agent_executions(status);
+
+-- Performance metrics
+CREATE INDEX idx_performance_metrics_session_id ON performance_metrics(session_id);
+CREATE INDEX idx_performance_metrics_metric_type ON performance_metrics(metric_type);
+```
+
+### Query Optimization
+
+1. **Batch Operations** - Use transactions for multiple related operations
+2. **Connection Pooling** - Reuse database connections efficiently
+3. **Async Operations** - Non-blocking database operations
+4. **Error Handling** - Graceful degradation on database failures
+
+### Data Retention
+
+```typescript
+// Clean up old data (default: 30 days)
+const cleanupResult = await agenticRAGDatabaseService.cleanupOldData(30);
+console.log(`Cleaned up ${cleanupResult.sessionsDeleted} sessions and ${cleanupResult.metricsDeleted} metrics`);
+```
+
+## Monitoring and Alerting
+
+### Health Checks
+
+The system provides comprehensive health monitoring:
+
+```typescript
+const healthStatus = await agenticRAGDatabaseService.getHealthStatus();
+
+// Check overall health
+if (healthStatus.status === 'unhealthy') {
+  // Send alert
+  await sendAlert('Agentic RAG system is unhealthy', healthStatus);
+}
+
+// Check individual agents
+Object.entries(healthStatus.agents).forEach(([agentName, metrics]) => {
+  if (metrics.status === 'unhealthy') {
+    console.log(`Agent ${agentName} is unhealthy: ${metrics.successRate * 100}% success rate`);
+  }
+});
+```
+
+### Performance Thresholds
+
+Configure alerts based on performance metrics:
+
+```typescript
+const report = await agenticRAGDatabaseService.generatePerformanceReport(
+  new Date(Date.now() - 24 * 60 * 60 * 1000), // Last 24 hours
+  new Date()
+);
+
+// Alert on high processing time
+if (report.averageProcessingTime > 120000) { // 2 minutes
+  await sendAlert('High processing time detected', report);
+}
+
+// Alert on low success rate
+if (report.successRate < 0.9) { // 90%
+  await sendAlert('Low success rate detected', report);
+}
+
+// Alert on high costs
+if (report.averageCost > 5.0) { // $5 per document
+  await sendAlert('High cost per document detected', report);
+}
+```
+
+## Error Handling
+
+### Database Connection Failures
+
+```typescript
+try {
+  const session = await agenticRAGDatabaseService.createSessionWithTransaction(
+    documentId,
+    userId,
+    strategy
+  );
+} catch (error) {
+  if (error.code === 'ECONNREFUSED') {
+    // Database connection failed
+    logger.error('Database connection failed', { error });
+    // Implement fallback strategy
+    return await fallbackProcessing(documentId, userId);
+  }
+  throw error;
+}
+```
+
+### Transaction Rollbacks
+
+The system automatically handles transaction rollbacks on errors:
+
+```typescript
+// If any operation in the transaction fails, all changes are rolled back
+const client = await db.connect();
+try {
+  await client.query('BEGIN');
+  // ... operations ...
+  await client.query('COMMIT');
+} catch (error) {
+  await client.query('ROLLBACK');
+  throw error;
+} finally {
+  client.release();
+}
+```
+
+## Testing
+
+### Running Database Integration Tests
+
+```bash
+# Run the comprehensive test suite
+node test-agentic-rag-database-integration.js
+```
+
+The test suite covers:
+- Session creation and management
+- Agent execution tracking
+- Quality metrics persistence
+- Performance tracking
+- Analytics and reporting
+- Health monitoring
+- Data cleanup
+
+### Test Data Management
+
+```typescript
