# Sankofa Phoenix: Data Model & GraphQL Schema

## Overview

The data model for **Sankofa Phoenix** is designed as a **graph-oriented structure** that represents:

* Infrastructure resources (regions, clusters, nodes, services)
* Relationships between resources (networks, dependencies, policies)
* Metrics and telemetry (performance, health, cost)
* Well-Architected Framework assessments
* Identity and access management
* Cultural intelligence and regional context

## Neo4j Graph Schema (Optional)

For complex graph queries, Neo4j can be used:

```cypher
// Node labels
(:Region)
(:Site)
(:Cluster)
(:Node)
(:Service)
(:Network)
(:Storage)

// Relationships
(:Region)-[:CONTAINS]->(:Site)
(:Site)-[:CONTAINS]->(:Cluster)
(:Cluster)-[:CONTAINS]->(:Node)
(:Service)-[:DEPENDS_ON]->(:Service)
(:Network)-[:CONNECTS_TO]->(:Network)
(:Resource)-[:AFFECTS_PILLAR]->(:Pillar)
```

## Integration Points

### Control Plane Adapters

The data model integrates with:

1. **Proxmox**: Cluster, VM, storage data
2. **Kubernetes/Crossplane**: Pod, service, network data
3. **Cloudflare**: Tunnel, DNS, network data
4. **Prometheus**: Metrics and telemetry
5. **Custom APIs**: Additional infrastructure sources

### Normalization

All control plane data is normalized into the unified graph model, allowing:

* Single source of truth
* Consistent query interface
* Cross-platform relationships
* Unified visualization

## Future Enhancements

1. **AI/ML Integration**: Model predictions and recommendations
2. **Cost Optimization**: Cost tracking and optimization recommendations
3. **Security Posture**: Security assessments and threat intelligence
4. **Compliance**: Compliance tracking and reporting
5. **Cultural Intelligence**: Enhanced cultural context and adaptation
