Cross-cutting concern

From Wikipedia, the free encyclopedia

Jump to: navigation, search

In computer science, cross-cutting concerns are aspects of a program which affect (crosscut) other concerns. These concerns often cannot be cleanly decomposed from the rest of the system in both the design and implementation, and result in either scattering or tangling of the program, or both.

For instance, if writing an application for handling medical records, the bookkeeping and 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.
