AOP is a way to deal with cross-cutting concerns in an application. Complex Web applications are a domain in which we find many cross-cutting concerns, spanning from presentation to content, from business logic to user agent and many more.
Being able to isolate all the different concerns in separate units of code and then being able to waeve them together in an aspect-oriented fashion would greatly simplify the application's architecture and improve its flexibility.
However, it's not always possible to use an AOP framework for the development of your Web application.
In this presentation we'll see how keeping a few AOP concepts in mind can lead to a better design. We'll also explore a few patterns that may help you to implement an aspect-oriented architecture even if you don't use an AOP framework.
