Specification of fact calculations within the MetaMIS approach

Based on recent work on the so called MetaMIS approach we show how fact calculations can be specified from a management point of view. The MetaMIS approach's intention is to specify management views on business processes. It comprises a language, a representation formalism and guidelines to define information required for management decisions. Information in general should have pragmatic meaning for the management user. Beyond the task of specifying information in this sense, fact calculations are required to manipulate information. Respective analyzing tasks typically deal with variances, growth rates and other relevant aspects of business processes. We extend the MetaMIS approach to enable the specification of fact calculations in data mart environments

Datenschutz als Rahmen für das Customer Relationship Management: Einfluss des geltenden Rechts auf die Spezifikation von Führungsinformationssystemen

Ziel dieser Arbeit ist es, die momentan geltenden nationalen Bestimmungen des Datenschutzes zu untersuchen und Ihre Auswirkungen auf den Bereich des CRM zu beleuchten. Dazu wird im nächsten Abschnitt zunächst das Konzept CRM erläutert. In Abschnitt 3 werden rechtliche Bestimmungen im Umgang mit personenbezogenen Daten diskutiert. Abschnitt 4 beschreibt, wie Kundendaten innerhalb des CRM unter Beachtung geltenden Datenschutzrechts verarbeitet werden können. Abschließend behandelt Abschnitt 5 die Spezifikation von analytischen Anwendungssystemen, die für Zwecke des CRM eingesetzt werden können und beschreibt, welche Implikationen geltendes Datenschutzrecht auf solche Spezifikationen hat

On the impact of the ‘linguistic turn’ on research in information systems

The linguistic turn within philosophy has recently gained increased attention within social sciences. It can be seen as an attempt to investigate traditional philosophical problems by analysing the linguistic expressions used for these investigations. More generally, the phenomenon of language itself must be considered because of its (constitutional) impact on the investigation of phenomena in social sciences. In order to understand the consequences of the linguistic turn, its origins in philosophy are important and will be discussed. Within social sciences the linguistic turn already had significant impact. As an example, we will therefore discuss what directions the linguistic turn enabled for organizational analysis. Information Systems as a discipline must face the consequences of the linguistic turn as well. We will discuss how the linguistic framework introduced impacts the development of knowledge management and that of managerial and organizational support systems. This example shows what different perspectives the linguistic turn can provide for investigations within Information Systems. In addition, we will briefly outline the impact of the linguistic turn with respect to methodologies in Information Systems research

Document Variant Management – Facilitating Enterprise System Definition, Configuration, and Interoperability

Enterprise Systems (ES) provide a standardized means to assist operations and management. Being off-the-shelf software, ES provide a generic approach and they have to be configured to the enterprise’s requirements. The customization of ES is a complex and costly task, therefore especially small and midsize enterprises (SME) flinch from doing so. Independent software vendors can assist SMEs in adapting ES to their needs. To be of reasonable economical value, it must be possible to facilitate the customization process with configuration mechanisms that allow generating customer specific processes and documents from a generic model-based repository. Several high-level configuration mechanisms are presented that add up to a comprehensive procedure for document variant management

An Epistemological Foundation of Concpetual Modeling

In a business environment, making the right decisions is vital for the success of a company. Making right decisions is inevitably bound to the availability and provision of relevant information. Information systems are supposed to be able to provide this information in an efficient way. Thus, within information systems development a detailed analysis of information supply and information demands has to prevail. Based on Szyperski’s information set and subset-model we will give an epistemological foundation of information modeling in general and show, why conceptual modeling in particular is capable of developing effective and efficient information systems. Furthermore, we derive conceptual modeling requirements based on our findings
