Layers vs. Tiers in Software Architecture: Analyzing Logical Organization and Physical Deployment
This article delves into the core distinctions between "Layers" and "Tiers" in software architecture. Layers refer to the logical organization of code, such as presentation, business, and data layers, focusing on functional separation without regard to runtime environment.
