# MIGRATION NOTES
# ============================================================================
"""
MIGRATION STRATEGY FROM ORIGINAL TABLES TO NORMALIZED SCHEMA:
1. DOCUMENT MAPPING:
- QEqeMaq (Equipment Import Temp) → items (type='EQUIPMENT_IMPORT_TEMP', system='SCAF')
- QEqeMaqRep (Equipment Repair Export) → items (type='EQUIPMENT_REPAIR_EXPORT', system='SCAF')
- QEqiDef (Equipment Import Definitive) → items (type='EQUIPMENT_IMPORT_DEF', system='SCAF')
- QEqiMaq (Equipment Machinery) → items (type='EQUIPMENT_MACHINERY', system='SCAF')
- QEqiMaqRep (Equipment Machinery Repair) → items (type='EQUIPMENT_REPAIR_IMPORT', system='SCAF')
- SPartidasCM (Common Commerce) → items (type='COMMON_COMMERCE', system='SCAII')
- SPartidasExpo (Export) → items (type='EXPORT', system='SCAII')
- SPartidasImpo (Import) → items (type='IMPORT', system='SCAII')
2. LINE MAPPING:
All line items from Q* and SPartidas* tables map to item_lines with appropriate
field mapping based on the original column names (preserved as comments).
3. FIELD CONSOLIDATION RULES:
- Costs: Unified under unit_cost_* with currency suffix (usd/mxn/mc)
- Values: Unified under value_* with currency suffix
- Quantities: Unified under quantity_* with specific purpose suffixes
- Descriptions: Consolidated into description_spanish/english/extra
- Fractions: All fraction fields preserved with clear naming
4. DATA INTEGRITY:
- Original CONSECUTIVO + LINE number preserved for traceability
- Foreign key relationships established via item_id
- All original fields retained to prevent data loss
5. SPECIAL TABLES:
- PackingList, RepairPart, CTM*, Subassembly*, ImpositionPart remain separate
as they serve specific purposes and don't fit the main item/line pattern
6. BENEFITS:
- Eliminates redundancy across 13 original tables
- Unified query interface for all operations
- Maintains full audit trail with original field names
- Enables cross-system reporting (SCAF + SCAII)
- Simplifies maintenance with single schema
7. QUERYING EXAMPLES:
```python
# Get all imports (both systems)
session.query(Item).filter(
Item.item_type.in_(['IMPORT', 'EQUIPMENT_IMPORT_TEMP', 'EQUIPMENT_IMPORT_DEF'])
)
# Get all lines for a specific part across all items
session.query(LineItem).filter(
LineItem.part_number == 'ABC123'
)
# Get SCAF equipment with depreciation
session.query(Item).join(LineItem).filter(
Item.system_origin == 'SCAF',
LineItem.value_depreciated_usd.isnot(None)
)
```
