  • ✅ Auto-calculate total scores from signals

2. Signal Tracking (/api/signals)

  • ✅ Store growth indicators for regions
  • ✅ Support multiple indicator types
  • ✅ Query signals by region
  • ✅ Update and delete signals

3. Hotspot Detection (/api/hotspots)

  • ✅ Retrieve regions ranked by total score
  • ✅ Configurable result limit
  • ✅ Shows region details with scores

4. Data Management

  • ✅ H2 in-memory database
  • ✅ JPA/Hibernate ORM
  • ✅ Sample data pre-loaded
  • ✅ Relationships properly mapped

5. API Design

  • ✅ RESTful endpoints
  • ✅ JSON request/response
  • ✅ Proper HTTP status codes
  • ✅ Input validation
