In our continuous exploration of Data Vault concepts during the Data Vault Friday series, our CEO, Michael Olschimke, takes on a thought-provoking question from a member of our audience.

“Can a work order ID or recommendation ID be considered a natural business key even though there is no business ‘meaning’ to these ids? or should I use the text description of the recommendation as the business key? The work order would have to be a composite key made up of details and a date for the work order which at that point seems like just using the ID makes more sense.”

Michael addresses the nuanced concept of Natural Key and Technical ID in the context of work order and recommendation IDs. The discussion provides valuable insights into making informed decisions about choosing business keys in scenarios where the identifiers lack inherent business meaning.
