Study Notes
Package Cohesion Principles
- There are two principles of package cohesion: the Common Closure Principle (CCP) and the Common Reuse Principle (CRP).
Common Closure Principle
- The Common Closure Principle aims to group classes that are likely to change together in the same package.
- It focuses on minimizing the work to rebuild, test, and deploy a release.
Common Reuse Principle
- The Common Reuse Principle is focused on grouping classes that are used together in the same package.
Test your knowledge of package cohesion and coupling principles in software design and architecture. Learn about the Common Closure Principle, Common Reuse Principle, Acyclic Dependencies Principle, and Stable Dependencies Principle.
