Kódkoherencia

Kódkoherencia is a Czech term that translates to "code coherence" or "code cohesion" in English. It refers to the degree to which the elements of a software module belong together. In essence, it measures how well the responsibilities of a module are focused and related. High code coherence means that a module performs a single, well-defined task or set of closely related tasks. Low coherence suggests that a module is trying to do too many unrelated things, making it harder to understand, maintain, and reuse.

This concept is closely related to the principles of good software design, such as modularity and separation of concerns. When a module has high coherence, its internal logic is tightly bound, and changes to one part of the module are less likely to affect unrelated parts. This leads to more robust and maintainable code. Conversely, a module with low coherence often indicates a design flaw. It might be a sign that the module should be split into smaller, more focused units.

Developers strive for high code coherence to improve the overall quality of their software. It contributes to easier debugging, better testability, and a more organized codebase. When examining existing code or designing new modules, assessing code coherence can be a valuable practice for identifying areas that might benefit from refactoring or redesign. The goal is to create modules that are as self-contained and purposeful as possible.
