Cohesion vs Coupling: Key Software Design Principles Explained
TL;DR: Cohesion: How closely related a class’s responsibilities are. Aim for high cohesion, each class should do one focused job well. Coupling: How dependent one class is on others. Aim for low coupling to make code easier to change, test, and maintain. Low coupling high cohesion lead to clean, modular, and maintainable object-oriented designs. Introduction to Cohesion vs Coupling in Software Engineering Ever stared at a massive class file with hundreds of lines of code and thought, “What is this thing even supposed to do?” I sure have. That confusion usually points to problems with cohesion and coupling in software engineering, two concepts that might sound academic but actually make the difference between code you want to work with and code you want to run away from. ...
