## Common Implementation Patterns

### 1. OAuth2 Token Management
```python
class OAuth2TokenManager:
    """Manage OAuth2 token lifecycle with automatic refresh."""
    
    def __init__(self, client_id: str, client_secret: str, token_url: str):
        self.client_id = client_id
        self.client_secret = client_secret
        self.token_url = token_url
        self.access_token: Optional[str] = None
        self.token_expiry: Optional[datetime] = None
    
    async def get_token(self) -> str:
        """Get valid access token, refreshing if necessary."""
        if self.access_token and self.token_expiry and self.token_expiry > datetime.now():
            return self.access_token
        
        return await self.refresh_token()
```

### 2. Data Product Analyzer
```python
def analyze_data_product(product_data: dict) -> dict:
    """Analyze data product usage and performance."""
    
    usage = product_data.get('usage', {})
    access = product_data.get('access', {})
    
    # Calculate usage metrics
    query_count = usage.get('queryCount', 0)
    export_count = usage.get('exportCount', 0)
    access_count = access.get('accessCount', 0)
    
    # Determine popularity
    if query_count > 1000:
        popularity = 'High'
    elif query_count > 100:
        popularity = 'Medium'
    else:
        popularity = 'Low'
    
    return {
        'popularity': popularity,
        'usage_score': min(100, (query_count / 10) + (export_count * 5)),
        'access_level': access.get('accessLevel', 'Unknown'),
        'shared_spaces': len(access.get('sharedWith', [])),
        'recommendations': generate_data_product_recommendations(product_data)
    }
```

### 3. AI Feature Monitor
```python
def monitor_ai_feature_health(status_data: dict) -> dict:
    """Monitor AI feature health and performance."""
    
    execution = status_data.get('execution', {})
    resources = status_data.get('resources', {})
    
    # Calculate health score
    success_rate = execution.get('successRate', 0)
    cpu_usage = resources.get('cpuUsage', 0)
    memory_usage = resources.get('memoryUsage', 0)
    
    # Health assessment
    health_score = (success_rate * 0.5) + ((100 - cpu_usage) * 0.25) + ((100 - memory_usage) * 0.25)
    
    if health_score >= 90:
        health_status = 'Excellent'
    elif health_score >= 75:
        health_status = 'Good'
    elif health_score >= 60:
        health_status = 'Fair'
    else:
        health_status = 'Poor'
    
    return {
        'health_score': round(health_score, 1),
        'health_status': health_status,
        'performance_trend': analyze_performance_trend(status_data),
        'resource_utilization': 'High' if max(cpu_usage, memory_usage) > 80 else 'Normal',
        'recommendations': generate_ai_recommendations(status_data)
    }
```

### 4. Security Compliance Checker
```python
def assess_security_compliance(config_data: dict) -> dict:
    """Assess security configuration compliance."""
    
    configurations = config_data.get('configurations', {})
    compliance_score = 0
    total_checks = 0
    
    # Check authentication
    auth = configurations.get('authentication', {})
    if auth.get('mfaEnabled'):
        compliance_score += 20
    if auth.get('passwordPolicy', {}).get('complexity') == 'High':
        compliance_score += 15
    total_checks += 2
    
    # Check data protection
    data_protection = configurations.get('dataProtection', {})
    if data_protection.get('encryptionAtRest'):
        compliance_score += 20
    if data_protection.get('encryptionInTransit'):
        compliance_score += 20
    total_checks += 2
    
    # Check auditing
    auditing = configurations.get('auditing', {})
    if auditing.get('auditLogging'):
        compliance_score += 15
    if auditing.get('realTimeMonitoring'):
        compliance_score += 10
    total_checks += 2
    
    final_score = (compliance_score / (total_checks * 20)) * 100
    
    return {
        'compliance_score': round(final_score, 1),
        'compliance_grade': get_compliance_grade(final_score),
        'critical_issues': identify_critical_issues(configurations),
        'recommendations': generate_security_recommendations(configurations)
    }
```

## Testing Strategy

### Unit Tests
1. **Data Sharing**: Test partner system discovery and marketplace browsing
2. **AI Features**: Test AI feature status monitoring and health assessment
3. **Configuration**: Test configuration retrieval and parsing
4. **Legacy APIs**: Test backward compatibility with DWC v1 APIs
5. **Security**: Test security configuration analysis

### Integration Tests
1. **Data Product Workflow**: Discover partners → Browse marketplace → Get product details
2. **AI Monitoring Workflow**: Get AI status → Analyze performance → Generate recommendations
3. **Configuration Management**: Get guided experience config → Get security config → Assess compliance
4. **Legacy Compatibility**: Test all legacy endpoints with real data

### Performance Tests
1. **Large Marketplaces**: Test with 1000+ marketplace assets
2. **AI Feature Monitoring**: Test with multiple AI features
3. **Configuration Loading**: Test large configuration objects
4. **Legacy API Performance**: Compare with modern API performance

---

## Security Considerations

1. **Data Sharing Security**: Validate partner system credentials and data sharing agreements
2. **AI Feature Access**: Ensure proper scopes for AI feature monitoring
3. **Configuration Security**: Protect sensitive configuration data
4. **Legacy API Security**: Maintain security standards for legacy endpoints
5. **Audit Logging**: Log all administrative and configuration access

---

## Success Criteria

- ✅ Can discover and analyze partner systems and data products
- ✅ Can browse marketplace assets with filtering and search
- ✅ Can retrieve detailed data product information and usage analytics
- ✅ Can monitor AI feature status and performance
- ✅ Can retrieve and analyze system configurations
- ✅ Can assess security compliance and generate recommendations
- ✅ Can access data through legacy DWC v1 APIs
- ✅ Proper error handling for all scenarios
- ✅ Performance acceptable for typical usage

## Next Steps

After implementing Phase 8:
1. Test with real SAP Datasphere tenant
2. Validate all endpoint accessibility
3. Performance benchmark with actual data
4. Create comprehensive usage documentation
5. **PROJECT COMPLETE** - All 49 tools implemented!
