Aspect-Oriented Middleware

The widening of the application spectrum has brings some difficult to design the architecture of middleware systems.The most prominent problem with middleware systems is that the architecture of middleware constantly struggles between generality and specialization.One of the fundamental problems in middleware architecture is that software decomposition models obtained using,vertical decomposition procedures are incapable of simultaneously modularizing coexisting orthogonal design requirements.This paper survey three Aspect Oriented approaches to developing middleware.AspectIX and QuO address the QoS concern,and DIL separates the protocol implementation from the functional code.The use of these tools in building a system will likely result in greater modularity,configurability and evolvability of the code.
