IT Applications have dominated every sector making the services online, there is a heartfelt need to standardize these applications so as when these applications when work in conjugation give better results real time for any kind of queries of customers maintaining levels of abstraction and information hiding. This paper aims at proposing a model for the on fly integration of the applications using context-aware self-adaptation approach for application service to cater to the need to integrate the data and services provided by the various applications. Our research within this direction has depicted the characteristics of the existing information and application systems primarily of the QoS Broker Architecture and Service Oriented Architecture. The latter part of this paper proposes an architectural model to describe the fly culmination of services by standardizing it and providing the result of a query using the context-aware engine. The aim of this paper is to study the existing systems, identify drawbacks and improve systems integrations to achieve an optimized and dynamic platform for real-time query processing.
