It demonstrates the capability of business processes to integrate primary and secondary functions in a firm. The main part of the course focuses on the business functions architecture of integrated information systems in industrial companies. In particular, functional interdependencies will be outlined in order to understand how business functions interact when horizontal or vertical business processes are executed. Finally, fundamentals of management support systems, such as data warehouses and business intelligence systems, will be addressed.

    This course is designed for Business Informatics students. It requires a profound level of conceptual systems design and development skills. Exchange students from other disciplines like Business Administration or Management may attend this course if they have already acquired profound knowledge in the domains of information systems and information technology.

    During the course, students will have the opportunity to work with ERP@School, a basic ERP systems which demonstrates the logic and interdependencies between business functions. The use of the system requires basic systems handling knowledge since it has to be conducted in self-learning sessions.
