Colloquium "25 years of data processing technology: From cost factor to innovation driver"


The title of the event was ambiguous: a) The aim was to present current and innovative IT applications in various areas of business and administration, to name the associated technical challenges and to compare them with the situation of data processing technology 25 years ago. Then PCs and workstations began to supplant mainframes and the need for smoothly networking heterogeneous hardware and software infrastructures posed interesting research problems. b) At the same time, the majority of invited speakers had supported Prof. Krämer 25 years ago in the rebuilding the Data Processing Technology Department with a new focus on distributed software technology.

After the welcoming addresses of the rector of FernUniversität, Prof. Aada Pellert, and the dean of the Faculty of Mathematics and Computer Science, Prof. Jörg Desel, Bern Krämer started his lecture with a journey through time beginning with Konrad Zuse's invention of the world's first programmable computer in 1941, the replica of which was presented in 2012 at a conference he organized in Berlin (see also a video of the ZMI explaining Horst Zuse's computer: https://www.fernuni-hagen.de/videostreaming/zmi/video/2012/12-23_00000/). While passing over various milestones, such as the standardization of open distributed data processing systems or programmable logic controllers, the invention of the WWW, the emergence of service-oriented computing, cloud computing, the Internet of Things (IoT) and edge computing, he explained the research questions his research group addressed and outlined related research projects and results.

Four presentations dealt with different aspects of the IoT and digitization of industry. A. Stuckenholz presented a low-energy communication infrastructure that enables a large number of sensors distributed over wide distances to transmit their measured data safely and in real time to suitable receivers and allows sensors and actuators to network spontaneously . U. Steinmann presented the latest technology incl. microprocessors, sensors and development environments for IoT applications, while T. Koch outlined an innovative project of Swiss Post that allows their clients to initiate postal and other services at the push of a button from home. S. Fakher's contribution picked up on the changes triggered by digitization in companies and introduced new forms of organization and talent development strategies, which lead to organizations being more adventurous than before and not being overwhelmed by disruptions, thereby effectively and purposefully employing the talents available in a company.

Two contributions addressed the central problem of IT or cyber security for the highly networked world. Financial systems, theIoT, cloud, edge computing and future IT innovations will not be sustainable unless a high level of data security is ensured. I. Scheler, who has been working in the banking sector for almost 20 years, outlined details and the development of threat scenarios over time and pointed out that a highly professional, downright cybercrime industry has emerged. This industry acts strictly according to business considerations and tries to generate maximum financial returns with minimal effort. To the extent that companies optimise their technical defence measures by means of cyber security, the weakest link, and thus the one attacked by cybercriminals, will become the weakest link in the process. U. Kalinna presented current technical defence solutions and discussed and analyzed spectacular security incidents from the last 3 years, which he knows from his teaching and consulting activities with police authorities. He also explained the operation of new security systems, including a development in which he is actively involved as a security expert and entrepreneur.

There were further two presentations on the topic of software-intensive production technology. D. Terstegge described the changes in the production processes of the chemical and pharmaceutical industry, which is highly regulated, and reported on new developments to make these processes smarter by using software and IoT equipment. B. Krämer explained the ideas and prototype solutions developed in the context of the Horizon 2020 project ICP4Life, which allow standard industrial products to be customized to meet new requirements by embedding specific sensors and new software services.

N. Völker reported on his approach, concrete teaching experiences and challenges with his beginner's course on object-oriented programming at Essex University.
