Aspect (computer programming)of a program is a feature linked to many other parts of the program, but which is not related to the program's primary function.
Isolating such aspects as logging and persistence from business logic is at the core of the aspect-oriented programming (AOP) paradigm.
Аспектлогический объект в аспектно-ориентированном программировании, который позволяет объединять однотипные по функциональности элементы разных объектов.
Cross-cutting concernsare aspects of a program that affect several modules, without the possibility of being encapsulated in any of them.
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 interact with more parts of the program.
Aspect weaveris a metaprogramming utility for aspect-oriented languages designed to take instructions specified by aspects (isolated representations of significant concepts in a program) and generate the final implementation code.
