### Performance & Scalability

- Chunked processing for large JSON imports (hundreds of MB)
- Sequential AJAX calls for bulk AI generation to avoid timeouts
- Optimized SQL queries with indexed lookups
- Browser-side state management for complex interactions

## Integration & Data Flow

### Input: SAP BW Metadata

DRAGON consumes JSON exports from SAP BW containing:
- Table metadata from key BW tables (RSDCUBE, RSOADSO, RSDODSO, RSTRAN, etc.)
- Query definitions from RSZELTXREF, RSZRANGE, RSZSELECT
- InfoObject definitions from RSDIOBJT
- Field labels from RSFBPFIELDT, RSTXTLG
- ABAP routine code from transformation tables

### Output: Structured Documentation

DRAGON produces:
- Interactive HTML dashboards for data lineage exploration
- Word documents with comprehensive query documentation
- JSON exports for integration with external tools
- AI-generated functional descriptions stored in database

### External Integrations

- **AWS Bedrock**: Claude 3.5 Sonnet for AI-powered text generation
- **SAP BW**: Metadata extraction via custom ABAP programs (external to DRAGON)
- **Cloud Platforms**: Export documentation for BigQuery, Snowflake, MS Fabric migrations

## Common Use Cases & Workflows

### Use Case 1: SAP BW to Cloud Migration

**Challenge**: Migrate 500+ queries from SAP BW to Google BigQuery
**DRAGON Solution**:
1. Import BW metadata JSON into DRAGON
2. Generate complete query documentation with AI descriptions
3. Visualize data lineage to understand source-to-target flows
4. Export documentation to Word for migration team
5. Identify redundant queries to reduce migration scope by 60%

**Outcome**: Faster migration, better documentation, reduced cloud costs

### Use Case 2: BW Landscape Understanding

**Challenge**: New consultant needs to understand complex BW landscape with 200+ Cubes and 1500+ queries
**DRAGON Solution**:
1. Access data lineage module to visualize object relationships
2. Navigate from Open Hub destinations backward to DataSources
