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.


The students

  • understand essential approaches to integrate business information systems and are able to explain the key concepts underlying these approaches
  • are able to explain and critically discuss the relevance of integration as well as problems and challenges associated with integration
  • are familiar with a differentiated concept of integration, are able to describe the demand for integration of business information systems, and can assess traditional approaches (e.g., CIM systems or ERP systems) with respect to meeting this demand
  • are able to classify and assess integration approaches that are based on data exchange formats and have the ability to implement these approaches using corresponding tools and technologies
  • know different database technologies, are able to assess these technologies as a means of integration, and have the ability to apply these technologies using selected tools
  • understand the structure of data warehouse systems, can describe a method for developing data warehouse systems, and are able to practically apply this method using selected tools 
  • know different forms of decision supporting information systems including knowledge-based expert systems, and are able to assess both prerequisites for applying these systems and prospective bene-fits of these systems

Constitutive meeting:
The constitutive meeting will take place on 25.04.2017, from 16:00 till 17:30 Uhr in room R09 R04 H02. This session will provide information about organzational aspects as well as inform you about the curriculum of our research group, including Enterprise Modeling 2.

This course will be held in English.

This lecture is part of Integration of Business Information Systems 1 and is linked closely to the respective tutorial. Therefore, some lectures might be interchanged with tutorial sessions (you will receive information about this during the semester via Moodle). We strongly advise you to take part in both parts of the module (lecture and tutorial) in the same semester.

There will be one module exam covering both contents from the lecture and tutorial (6 CP).
