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.

Dirk's detailed explanation and hands-on exercises helped me to proceed with the topic with ease. For anybody serious about the depths of bi-temporal data in data warehouses, I highly recommend Dirk's training.
