I was very satisfied with Dirk Lerners Temporal Data in a Fast-Changing World! training. The training answered all my question about bi-temporality, not addressed in other Data Vault trainings with such clarity.
The webinar series prepares you for the DMC certification in an entertaining way. Many questions, helpful exchange between the participants. And Dirk, who always seems to know the answer!
Since more than 15 years I’m working with bitemporal data in Data Warehouse solutions. Meanwhile it is easy to design, build and populate tables for bitemporal data. But how to design and build bitemporal dimensional modeled Data Marts was new to me. Dirk Lerner does a very good job in explaining complex bitemporal stuff.
Dirk Lerner and his presentation on bitemporal modeling at first gave me a brain freeze. However, his explanation of using a Data Vault satellite to track changes over time and collapsing the changes into a dimension for analytics was not only a requirement for financial reporting in Germany but also quite ingenious.
