Model driven decision making @ #BAS19

FastChangeCo and the Fast Change in a Hybrid Cloud Data Warehouse with elasticity

What is this 20 minute talk about at #BAS19?

The fictitious company FastChangeCo has developed a possibility not only to manufacture Smart Devices, but also to extend the Smart Devices as wearables in the form of bio-sensors to clothing and living beings. With each of these devices, a large amount of (sensitive) data is generated, or more precisely: by recording, processing and evaluating personal and environmental data.

13 tips to make your Data Vault project fail

Or how to successfully destroy every level of the data warehouse

Dirk, I just read an article from you about Data Vault Modeling and the 13 tips for failure in the BI spectrum. A very interesting article with really good tips. Thanks a lot for that.Christian Ehrentraut, BI & Data Engineer

Are you pampered with success and tired of the eternal pat on the back? You don't want to be so successful with your first attempt at implementing a Data Vault project that all your colleagues become jealous?

Reporting- und Business-Intelligence-Werkzeuge für den Controller Front Cover

Reporting- und Business-Intelligence-Werkzeuge für den Controller

Anfang letzten Jahres, genauer gesagt am 16. April ist das dritte Buch erschienen, zu dem ich ein Kapitel beigesteuert habe. Das Arbeiten an dem Kapitel hat wieder viel Spaß gemacht, vor allem auch wegen des tollen reportingimpulse-Teams. Aber nun zum Buch:

Wie im Einleitungskapitel zu diesem Buch dargestellt, sehen sich Controller heutzutage vielfältigen neuen Herausforderungen gegenüber. Dies ist hauptsächlich getrieben durch eine rasante technologische Entwicklung und häufige, in kurzen Intervallen, veränderte Anforderungen in der Geschäftswelt.

Reflections on Global Data Summit 17

This blog post will be a review of the Global Data Summit. But first I would like to lose a few sentences about the Advanced Data Vault & Ensemble Modelling meeting, organized by Hans Hultgren and Remco Broekmann. It is an event that brought together experienced data modelers from all over the world (New Zealand, South Africa, Europe and the USA) around Data Vault, Focal and Ensemble Logical Modeling (ELM). That sounds promising, doesn't it?

Advanced Data Vault & Ensemble Modelling

There were two interesting days with many topics around Data Vault and ELM, which were put up for discussion. The idea behind the meeting is to think further, e. g. where to go with Data Vault and ELM and what the participants can contribute from their own experiences. I personally find some of the points discussed very interesting and exciting and should be pursued further. With others I have to go into myself and continue researching. Most likely, I'll go into other blog posts on different topics, such as the discussion about concatenated key, partitioned links or how you can do without satellites on links. I will see.

  • FOM

    Fact-Oriented Modeling (FOM) stands for a family of fact-oriented conceptual modeling methods. FOM facilitates easier communication about the conceptual model between the modeler and the domain expert by verbalization of concrete examples in the language of the domain expert, a design process as a guide for creating the model and the focus on elementary facts. The most popular methods in this family are Cognition Enhanced Natural Language Information Analysis Method (CogNIAM), Second Generation Object Role Modeling (ORM 2) and Fully Communication Oriented Information Modeling (FCO-IM).
