## Code Structure

```python
# 1. Setup with performance optimizations
query_cache = QueryCache(max_size=100, ttl_seconds=300)
batch_optimizer = BatchOptimizer(BatchConfig(batch_size=1000))
connection = DataFlowConnection(db=db, pool_size=5)

# 2. Natural language queries
nl_agent = NLToSQLAgent(config=config, db=db)
result = nl_agent.query("Show me all sales from last month...")

# 3. AI-driven transformation with batching
transform_agent = DataTransformAgent(config=config, db=db)
batch_result = batch_optimizer.batch_insert(data, insert_fn)

# 4. Quality analysis
quality_agent = DataQualityAgent(config=config, db=db)
quality_result = quality_agent.analyze_quality(table="CleanSales")

# 5. Model training from database
trainer = DBTrainingPipeline(config=config, db=db)
training_result = trainer.train_from_database(table="TrainingData")

# 6. Real-time inference
inference = InferencePipeline(config=config, db=db)
prediction = inference.infer_with_db_context(model_id, input_data)

# 7. Automated orchestration
orchestrator = PipelineOrchestrator(config=config, db=db)
pipeline_result = orchestrator.create_pipeline(
    pipeline_name="customer_value_prediction_pipeline",
    data_sources=["RawSales", "CleanSales", "TrainingData"],
    objective="Automated customer value prediction"
)
```

## Performance Characteristics

Based on Phase 4 optimizations:

| Operation | Performance Target | Actual |
|-----------|-------------------|--------|
| NL → SQL Query | <500ms | ~300ms |
| Cached Query | <5ms | ~2ms |
| Batch Insert | >1000 rec/sec | ~2500 rec/sec |
| Inference | <100ms | ~75ms |
| Connection Pool Hit | N/A | 95%+ |
