How can I measure cohesion in software modules?

Cohesion in software modules can be measured using several metrics, such as the Lack of Cohesion of Methods (LCOM). This metric evaluates how closely related and focused the methods within a module are.

What are some other metrics I can use?

Other metrics include the number of parameters, the number of methods, and the degree of interdependence between modules. Each provides insights into the module's design.

Why is measuring cohesion important?

Measuring cohesion is crucial because high cohesion often leads to better maintainability, readability, and reusability of code, which enhances overall software quality.

Can you give an example of high vs low cohesion?

Sure! A module with high cohesion might contain methods that all relate to user authentication, while a module with low cohesion might have methods for user authentication, data processing, and file handling all mixed together.
