In our continuous Data Vault Friday series, our CEO Michael Olschimke addresses an intriguing question from our audience.

“If I need to historize the reference table, I can use the Satellite pattern. Ok, I have now a Reference Satellite table. But what about the Reference Hub table? Is it effective to create a table with just one column?”

In this informative video, Michael explores the concept of historizing reference tables within Scalefree’s Data Vault 2.0 projects. The question specifically focuses on the efficiency and effectiveness of creating a Reference Hub table with just one column.

Michael shares insights into the considerations and scenarios where creating a Reference Hub table with a single column can be a viable and effective approach. The discussion provides practical guidance for handling reference tables within the Data Vault 2.0 methodology.
