Common Use Cases

Analyze ERP Integration

analyzer = ERPIntegrationAnalyzer()

# Define ERP system
erp = ERPSystem(
    name="SAP S/4HANA",
    vendor="SAP",
    version="2023",
    modules=[
        ERPModule.FINANCE,
        ERPModule.PROJECT_MANAGEMENT,
        ERPModule.PROCUREMENT,
        ERPModule.COST_CONTROL,
        ERPModule.HR,
        ERPModule.BILLING
    ],
    database="HANA",
    has_api=True,
    api_type="REST"
)

# Define external systems
external = [
    {"name": "Procore", "type": "project_management"},
    {"name": "Revit", "type": "bim"},
    {"name": "Primavera", "type": "scheduling"}
]

# Define integration points
points = [
    IntegrationPoint(
        id="erp-procore",

analysis = analyzer.analyze_erp_integration(

    external_systems=external,
    integration_points=points
)

print(f"Integration Score: {analysis.integration_score:.0%}")
print(f"Bottlenecks: {len(analysis.bottlenecks)}")

Monitor Integration Health

monitor = IntegrationHealthMonitor(integration_points)

health = monitor.check_health()
print(f"Status: {health['overall_status']}")

if health['issues']:
    for issue in health['issues']:
        print(f"  - {issue['point']}: {issue['message']}")

# Generate report
report = monitor.get_health_report()

Compare Integration Options

options = [
