Preliminary knowledge

Abstract

This lecture continues from where the lecture ‘Integration of Business Information Systems I’ left off. The lecture starts with the discussion of advanced requirements for integrating corporate information systems. It is supplemented by idealized models of the evolution of system architectures. Against this background, a reference model for the description and evaluation of what is called middleware will be presented. It serves as a framework for describing and discussing selected middleware systems, such as CORBA and J2EE. In recent years, component technologies have attracted a remarkable amount of attention. However, to date there is no unified terminology. The lecture presents a notion of a component, which allows it to be discriminated from the notion of an object or a class. Web Services are regarded by some as a silver bullet for establishing process-oriented information systems – usually in conjunction with workflow management systems. This claim will be analysed in detail. Subsequently, objectives, technologies and methods for integrating existing application infrastructures will be presented and evaluated. This includes taking into account approaches to Enterprise Application Integration. Finally, the lecture will demonstrate how complexity and risk related to integration projects can be reduced by a dedicated modelling method. It is recommended that participants attend the accompanying tutorial.
