Cross-cutting Concern
In computer science, cross-cutting concerns are aspects of a program that affect other concerns. These concerns often cannot be cleanly decomposed from the rest of the system in both the design and implementation, and can result in either scattering (code duplication), tangling (significant dependencies between systems), or both.
For instance, if writing an application for handling medical records, the indexing of such records is a core concern, while logging a history of changes to the record database or user database, or an authentication system, would be cross-cutting concerns since they touch more parts of the program.

Famous quotes containing the word concern:
“What right those who govern have to govern they don’t question, they just govern. Whether the people have a right to depose them that doesn’t concern them. All they are concerned with is that the people will not be tempted to depose them.”
—Johann Wolfgang Von Goethe (1749–1832)
