Aspect-oriented software development is a broad area with many examples and ways the technology is used. These are often depicted as use cases that are basically about the crosscutting concerns of the system. Though still a new programming technique, Aspect-oriented software development, AOSD, has several areas of application in software development.
Below are many ways AOSD is used:
The Security issue is crucial in any software and software development process. For this, the application of security in a system must be a global concern and should be consistently applied. Using aspect-oriented software development, you can develop a Security Manager class for the program. If security concern is left out in any area, it can result in a system flaw. Aspect-oriented software development deals with this by ensuring security concerns are specified in a modular form and implemented in the main program in a unified manner.
Logging in software is necessary to know the internal information of execution. This is for the purpose of understanding software behavior, debugging, testing and other requirements. Logging presents a cross-cutting concern as every logged part of the system is affected. Aspect-oriented software development takes care of this by using a non-intrusive method.
Authentication And Authorization
Authentication is whether or not a user is given access to particular software. Authorization governs what functions are available to a user in the system. Authorization policies cover groups of roles, systems, users, and commands. The benefits of using aspect-oriented software development are the ability and the possibility it has to put corporate-based authorization in place. This enables the corporate view to be mapped to the corporate system infrastructure. Once this is implemented, the modification can be done centrally.
Today’s applications are usually complex with many threads, and distribution systems that utilize third-party components. Such systems present the difficulty to detect the root cause of reliability and performance issues. AOSD allows you to define point cuts that match the join points where performance is to be monitored. You can then code advice that updates performance records which can be automatically invoked any time one exits or enters any join points.
There are many other ways of application of AOSD aside from the few discussed above. These include performance optimization, synchronization, tracing, design patterns, exceptional detection and handling, and coordination protocols in middleware.
