  • Data (Vault) Modeling and Deep Learning @ #XP19

    Model driven decision making

    During #XP19 you’ll be able to take part in our (Matze and myself) deep dive session about Model driven decision making: Data (Vault) Modeling and Deep Learning. It has been designed to give you a (very) short hands-on and practical guidance.

    What is this 15 minute deep dive session about at #XP19?

  • 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.

  • Follow Up Data Vault EXASOL Webinar

    In July 2016 Mathias Brink and I had given a webinar how to implement Data Vault on a EXASOL database. Read more about in my previous blogpost or watch the recording on Youtube.

    Afterward I became a lot of questions per our webinar. I’ll now answer all questions I got till today. If you have further more questions feel free to ask via my contact page,via Twitter, or write a comment right here.

  • 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.

  • High performance - Data Vault and Exasol

    You may have received an e-mail invitation from EXASOL or from ITGAIN inviting you to our forthcoming webinar, such as this:

    Do you have difficulty incorporating different data sources into your current database? Would you like an agile development environment? Or perhaps you are using Data Vault for data modeling and are facing performance issues?
    If so, then attend our free webinar entitled “Data Vault Modeling with EXASOL: High performance and agile data warehousing.” The 60-minute webinar takes place on July 15 from 10:00 to 11:00 am CEST.
  • High-performance Data Vault

    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.
