katmanldr

Katmanldr is a term encountered in Turkish-language software engineering discussions to describe layered software architecture approaches. It is not a formal standard, and its exact meaning can vary by author. In most discussions, katmanldr refers to organizing system functionality into distinct layers that communicate via well-defined interfaces.

Typical layers include presentation, application or business logic, domain model, data access, and integration. The goal is to separate concerns so that changes in one layer have limited impact on others. This separation supports maintainability, testability, and the ability to swap technologies at a boundary with minimal disruption.

Relation to established patterns: katmanldr is reminiscent of patterns such as MVC, MVVM, Clean Architecture, and Onion Architecture; the emphasis is on layering and interface contracts rather than any single implementation. Practitioners may use katmanldr as a generic description of a layered approach or as a shorthand for a project structure that enforces layer boundaries.

Implementation considerations include directing dependencies toward the inner layers, defining stable interfaces, and maintaining testability across boundaries. Tools and frameworks may enforce layering but should avoid unnecessary boilerplate or artificial constraints that hamper real-world requirements.

Advantages include improved maintainability, testability, and scalability; drawbacks can include added complexity, potential performance overhead from cross-layer communication, and the risk of over-engineering. Usage examples range from web applications and APIs to data-processing pipelines and mobile apps where modularity is valued.

Note: katmanldr appears primarily in Turkish-speaking communities as an informal descriptor rather than a formal standard. In some contexts it may also appear as a project name or library alias. See also Layered architecture, Clean Architecture, Hexagonal Architecture, MVC.
