Cross-cutting concern
From Free net encyclopedia
In computer science, cross-cutting concerns, or crosscutting concerns, are aspects of a program that crosscut the program design, i.e. applying a crosscutting concern to a program decreases the program modularity by either scattered or tangled code.
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.
