Research On Selfadaptation Middleware Systems

Nowadays, middleware has become a universal and widespread resolving plan whenimplementing the enterprise information application system. Especially when internet hasbecome the main running environment and the pushed by the force of SOA (Serviceorientedarchitecture), the requirements of the customers and hardware resources have been changingfrequently due to the opening and variability of the internet. This enhances the variability andcomplexity of the middleware. Many commercial areas, such as Telecom, Banks, requireselfadaptableability in their software system.Component software mode of software production can support a research from amacroscopic view. However, the inherent complexity of SA (Software Architecture) and SOAstyle put forward new challenges for selfadaptiveresearch. A kind of flexible adaptivemiddleware infrastructure based on formalized description and coarsegrainedservice integration,which can meet high demands of interactive, flexibility and reusability is urgently needed.This thesis take open source technique such as SCA,OSGI and Spring as it's infrastructure,introduce dynamic architecture metamodelto build a dynamic,flexible middleware Frameworkwhich designed with IOC and AOP assemble way to build loose coupling architecture. TheFramework provide formalized description and enhanced reusability that enable applications cancope with variable environment. In conclusion, we show an example in Adult Education System,It testified our framwork can implement adaptive operation and integrality checking.
