Daily Term: Cross-Cutting Concern

Cross-Cutting Concern

A Cross-Cutting Concern is functionality that affects multiple parts of a system, such as logging, security, or transaction management. For example, logging every method call in an app spans many components, leading to code duplication if not handled properly. Cross-cutting concerns are often managed using techniques like AOP or decorators to keep code DRY, but they require careful design to avoid scattering logic across the system.
