Abstract

The discussion in thesis involves two significant information science topics. These being Enterprise Application Integration along with Quality of Service. The quantity of information is enormous and humans have lost the ability to manage, interpret, and analyze the data. From this perspective, we target the concept of the "Digital Cockpit" which is a data/service enterprise integration built on the very concepts of loosely coupled asynchronous communication, Message Oriented Middleware, and real time integration and monitoring with interactive display. This is then followed by a new Quality of Service model viewing this issue from the perspective of information quality and accuracy as opposed to other existing similar systems. Our contributions are the following: First we present a literature review covering enterprise application integration and web services quality of service. Second we continue the discussion and propose a novel integration middle called "Digital Cockpit" where we highlight significant issues related to the specifications, design and implementation of that system. Moreover, We extend the discussion to include a novel approach concerning quality of service for web services composition. This is achieved by utilizing the new WS-Notification standard along with the use state charts. Fourth, we propose a mathematical framework which specifies and manages the quality from the information accuracy perspective. Therefore, each chapter of this thesis adds its own contribution and goes deeper into the discussion providing more technical and theoretical insights concerning the topic of discussion.
