Aspect-oriented programming

Aspect oriented programming, which is also known as AOP is a technique, which can be used to develop reusable and common routines, which can be applied across an application. During the agile development process, this would enable the separation of primary application logic from the repetitive and common tasks. Some perfect examples for such repetitive and common tasks include logging, input validation, and error handling.

During a runtime, you will be able to use Aspect Oriented Programming in order to hot-patch the applications, which are susceptible to embed intrusion detection and SQL injection. There is no need to modify underlying code in order to offer these functionalities. Along with the centralization of all security logics, it is possible to save time when developing a product in an agile environment.

There are some significant differences in between object oriented programming and aspect oriented programming. The main objective of object oriented programming is to promote flexibility and reusability of code. In the meantime, aspect oriented programming would act as a paradigm, which will deliver all benefits that are offered with object oriented programming. On top of that, it is possible to have loose coupling, and provide applicable the chance to use pluggable aspects as required. This will help the developers to refrain from making any changes to the code in order to bring in new functionality.

Developers who adhere to aspect oriented programming will also be able to focus entirely on the business logic of the application, while weaving the aspects to the overall business logic. Among the benefits that come along with AOP, the most prominent benefit would be the ability to write the aspects once and reuse them over and over again within the application as needed. Hence, it is a great method available to reduce code complexity.
