### Design Patterns

- **Factory Pattern**: Standardized component creation across exchanges
- **Observer Pattern**: Event-driven data processing and callbacks
- **Strategy Pattern**: Pluggable data processing strategies
- **Singleton Pattern**: Centralized logging and configuration management

## 🚀 Quick Start

### Using Components

```python
# Data Collector usage
from data.exchanges import create_okx_collector
from data.base_collector import DataType

collector = create_okx_collector(
    symbol='BTC-USDT',
    data_types=[DataType.TRADE, DataType.ORDERBOOK]
)

# Logging usage
from utils.logger import get_logger

logger = get_logger("my_component")
logger.info("Component initialized")
```

### Component Integration

```python
# Integrating multiple components
from data.collector_manager import CollectorManager
from utils.logger import get_logger

manager = CollectorManager("production_system")
logger = get_logger("system_manager")

# Components work together seamlessly
await manager.start()
logger.info("System started successfully")
```

## 📊 Performance & Monitoring

### Health Monitoring

All components include built-in health monitoring:

- **Real-time Status**: Component state and performance metrics
- **Auto-Recovery**: Automatic restart on failures
- **Performance Tracking**: Message rates, uptime, error rates
- **Alerting**: Configurable alerts for component health

### Logging Integration

Unified logging across all components:

- **Structured Logging**: JSON-formatted logs for analysis
- **Multiple Levels**: Debug, Info, Warning, Error levels
- **Automatic Cleanup**: Log rotation and old file cleanup
- **Performance Metrics**: Built-in performance tracking
