Learn about aspect-oriented design patterns and how they can be used to quickly add common functionality to your business objects. Josh Heyse explains how Aspect-Oriented Programming allows for the separation of true business logic and the code written allowing interaction with user interfaces. The Core framework is a generation model that dynamically adds common services, such as logging, auditing, persistence, and security to business objects. Aspects, or behaviors, are requested using attributes or configuration files which allows services to be included only where necessary eliminating overly bloated objects and tailored for the environment into which the object is loaded.
