📬 API Usage Examples (Postman / cURL)

Example endpoints you might test:

• Get All Items GET /api/demo/items

• Get Item by ID GET /api/demo/items/{id}

• Create Item POST /api/demo/items

  {
    "name": "Sample Item",
    "description": "This is just a demo item"
  }

• Update Item PUT /api/demo/items/{id}

• Delete Item DELETE /api/demo/items/{id}

📈 Possible Enhancements

• Add more entities & relations
• Introduce authentication / authorization
• Use DTOs & map mapper (MapStruct or similar)
• Add more tests: edge cases, integration tests
• Add API documentation (Swagger / OpenAPI)
• Externalize configuration & profiles (dev / prod)
