In 2011 at the Oracle OpenWorld conference, I attended a presentation of Kent Graziano about Data Vault Modeling. It was the first time I heard of this special modeling method for Data Warehouses, and after this session I was a bit confused about these data models with hubs, links and satellites. Is it really something new, or is it more or less the same technique we are using for master data versioning using head and version tables?
