Preliminary knowledge



Designing and implementing corporate information systems are pivotal topics of ‘Wirtschaftsinformatik’. While the modules ‘Enterprise Modelling I’ and ‘Enterprise Modelling II’ mainly focus on analysis and conceptual design, this lecture emphasizes a bottom-up perspective on implementation level artefacts, such as applications, technologies, and standards. Methods and technologies to develop integration systems as well as to foster the integration of existing systems are at the core of the lecture. The lecture starts by motivating the need for integration and reusability. Since integration is a vastly overloaded term, the students will be provided with a concept of integration that accounts for the peculiarities of information systems and can be applied to organizational integration – IT business alignment – as well. To further illustrate the need for integration in current IT landscapes, the participants will get an overview of functions covered by traditional business applications such as systems for accounting, human resource management, or production planning. Against this background, key approaches to promote the integration of corporate information systems will be presented and evaluated. This will include data exchange formats for loosely coupled systems and corresponding standards, database technologies as well as persistence in general. These approaches will be discussed and evaluated from both software-engineering and managerial perspectives. The presentation of decision support systems will provide further insights into the need for integrated information systems. For this purpose, their conceptual foundation and the need to integrate them with operational level systems will be analysed. Having gained an appropriate understanding of the concepts and technologies presented in the lecture, students are given the opportunity to practice their use in the accompanying tutorial.
