Lunchtime Seminar

Conceptual Model for Data Warehouse Systems
Tuesday, 25. July 2017 - 12:00 to 13:00, Leo 18

Speaker: Prof. Dr. Dr. h.c. Dr. h.c. Jörg Becker

Abstract:

Jörg presents a conceptual model as basis for BI systems. Many companies suffer from inconsistent data in their data warehouse systems, and quite often, there is more than one of these in a company installed. Every new requirement of a department in a company concerning aggregated data results in a new report the IT department builds fulfilling these requirements. What we observe are hundreds of dimension tables and thousands of facts tables in different systems (Cognos, SAP SD, SAP CRM, SAP BW, self developed systems). The same data is shown in different systems differently (means: different values of the same ratio). So, nobody in the company beliefs that the data is „right“ and everybody starts to create another „truth“ by extracting some data from different reports importing them into EXCEL. To evercome some of these difficulties, Jörg presents a new paradigm for Management Information Systems.
