Discuss a data model

This year’s European Data Modeling Zone (DMZ) will take place at the wonderful German capital Berlin and I’m very happy to be again speaker at this great event! This year I’ll speak about how to start with a conceptual model, using a logical model and finally how to model the physical Data Vault. During this session we will do some exercises (no, no push-ups!!) to bring our brains up and running about modeling.

Data Vault on EXASOL - Modeling and Implementation

On July 15, Mathias Brink and I ran a webinar about Data Vault on EXASOL, modeling and implementation. The webinar started with an overview of the concepts of Data Vault Modeling and how Data Vault Modeling enables agile development cycles. Afterwards, we showed a demo that transformed the TPC-H data model into a Data Vault data model and how you can then query the data out of the Data Vault data model. The results were then compared with the original queries of the TPC-H.

Generating large example data with TPC-H

Several times I had the need for some large data sets to do some Data Vault tests at customer site, writing a blogpost, doing a demo or a webinar and many more. And sometimes I need data to do performance or data usage tests on different databases. Due to my work together with EXASOL I focused on the TPC-H tool DBGen to generate gigabytes of data.

To share my experience with DBGen generating large data sets I wrote this blogpost as a step by step instruction.

Last week in June I was at the TDWI Conference 2016 at Munich. ITGAIN, my employer, had as a platin sponsor a booth to present our products and services!

In my point of view, it was another great TDWI conference at Munich with a lot of awesome people I could talk with - including an interesting discussion about data architecture with Mark (Madsen) and all the nonsense happening in the Big Data world.

Möglicherweise bringt dich der Erfolg dorthin, wo du nicht sein willst. Es hängt von dir ab, ob du weitergehst oder deinen Wurzeln treu bleibst."
