Ich freue mich sehr, den Roundtable vom März diesen Jahres jetzt virtuell nachholen zu können.

Mit der Zeit verändern sich Informationen auf komplexe Art und Weise. Zum Beispiel ändern sich die Zuordnung von Produkten zu Produktgruppen oder auch die Zuordnung von Preisspannen der Produkte nach Zielgruppe, Vertriebskanal, Rabattsystem und vieles mehr im Zeitverlauf.

Fachbereiche planen bereits heute zukünftige Preise und Preisspannen, strukturieren Produktgruppen um, wie zum Beispiel für eigene Produktgruppen mit Rabatten speziell für den "Black Friday". Diese Informationen können und werden lange bevor sie in der Realität gültig sind, in den Systemen gespeichert.

I, Stephan, am very happy that I'm invited to give a presentation at the Knowledge Gap 2020 in Munich.

My presentation is about advanced techniques in Fact-Oriented Modeling.

Often data models are built with a technical focus, because they need to be delivered fast or must meet various technical requirements. Therefore, the business aspect and the meaning of objects and relationships are swept under the table. But then the business domain later hardly understands the data model and has problems to work with it in own applications or reports – which often results in a redesign of the data model and renewed time and cost expenditures.

An EXASOL Webinar serie

We are back again after a long time, with a new webinar. The last one, we (Mathias and I) did together is almost four years ago. Time flies by! What's up this time?

The fictitious company FastChangeCo^TM 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.

I am pleased to say that I will be participating at this year’s Enterprise Data & Business Intelligence and Analytics Conference Europe 18-22 November 2019, London. I will be speaking on the subject ‘From Conceptual to Physical Data Vault Data Model’ and (for sure) on my hobby horse subject temporal data: ‘Send Bi-Temporal Data from Ground to Vault to the Stars’. See my abstracts for the sessions below.
