The Service applies business rules. The Repository saves the data. The Database stores the employee record. The API returns the appropriate response. 🚀 Why Use Feature-Based Architecture? ✅ Easy to understand and navigate ✅ Faster modifications and debugging ✅ Better separation of business functionality ✅ Easier unit testing and maintenance ✅ Simpler addition of new modules ✅ Suitable for growing ERP applications For example, when adding an Attendance, Leave Management, Procurement, or CRM module, you can follow the same structure without cluttering unrelated features.
