Some time ago a customers asked me how to load easy and simple some (test)data into their database XYZ (chose the one of your choice and replace XYZ) to test their new developed Data Vault logistic processes.
The point was: They don’t want to use all this ETL-tool and IT-processes overhead just to some small test in their own environment. If this this is well done from a data governance perspective? Well, that’s not part of this blogpost. Just do this kind of thingis only in your development environment.

Past, present and future, where did I speak and where will I speak at conferences?

Since my calendar fills up more and more with presentations at conferences I'll give you a summary to keep track on it. Some of them are already confirmed, for others I've submitted my abstracts but yet not confirmed.

TPC-H benchmark data model

Over the last few weeks, Mathias Brink and I have worked hard on the topic of Data Vault on EXASOL.

Our (simple) question: How does EXASOL perform with Data Vault?

First, we had to decide what kind of data to run performance tests against in order to get a feeling for the power of this combination. And we decided to use the well-known TPC-H benchmark created by the non-profit organisation TPC.

Second, we built a (simple) Data Vault model and loaded 500 GB of data into the installed model.  And to be honest, it was not the best model. On top of it we built a virtual TPC-H data model to execute the TPC-H SQLs in order to analyse performance.


Do you want to learn something about data modelling with Steve Hoberman? You want to explore new methods like Data Vault 2.0, Anchor Modeling, Data Design, DMBOK and many more? E.g. a keynote where Dan Linstedt, Lars Rönnbäck and Hans Hultgren talks together, and another one with Bill Inmon?

Last week, there was it again. A meeting of Data Vault geeks and interested people in Data Vault! And again in the wonderful area of Vermont, USA. But these year we hat +30°C compared to last year’s -20°C. In Stowe, Vermont, the conference was held in the wonderful Trapp Family Lodge. To give you some more insights I’ll embed some of the tweets. If you want read the full timeline, go here!


K – Keep (Data Vault)

I – It (ETL in your Data Warehouse)

S – Small (lightweight processes aka short and easy SQL)

S – and simple (easy Inserts and Updates)

Wie bereits in meinem Blogpost Modellierung oder Business Rule beschrieben ist es notwendig sich bei der Datenmodellierung über Geschäftsobjekte, die Wertschöpfungskette, fachliche Details und die Methodik des Modellierens einige Gedanken zu machen.

Oder doch nicht? Kann ich mit Data Vault einfach loslegen? Schließlich ist Data Vault auf den ersten Blick ganz einfach. Drei Objekte: HUBs, LINKs und SAT(elliten), einem einfachen Vorgehensmodell und ein paar wenige Regeln. Brauche ich für Data Vault noch die Datenmodellierung?
