.NET·1ySeparation of Concerns Principle: A Reflection after a job-interview
The author's reflection on the Separation of Concerns (SoC) principle in software development, sparked by a challenging job interview. They discussed why passing request models directly through layers is considered bad practice and the importance of using Data Transfer Objects (DTOs) to maintain clear boundaries and reduce complexity. The post emphasizes the importance of implementing SoC properly to enforce isolation between layers and enhance security.
Just Java·1yFactory Design Pattern
The Factory Design Pattern is a creational pattern that centralizes object creation logic, providing a way to instantiate objects without exposing the instantiation details to the client. This promotes loose coupling, easier maintenance, and extensibility. A real-world example in a healthcare ERP system demonstrates how different reports (e.g., Pharmacy, Billing, Inpatient) can be generated using this pattern. The pattern is beneficial for runtime object type determination, decoupling client code, and centralizing complex creation logic.
Community Picks·1yAvoid Returning Null From Methods – There Is a Better Way To Write Them!
Nullable reference types have improved C# by reducing NullReferenceExceptions, yet returning null from methods can make domain models less expressive. Instead, always return a proper object. By introducing types with valid defaults, avoid the need to handle nulls, simplifying both producers and consumers of objects. This follows the Null Object pattern, promoting more robust and maintainable code.
