To make a full transition from the existing DW model to an alternative Data Vault I removed all Surrogate Keys and other attributes that are only necessary to support Kimball data warehouse methodology. Also, I needed to add necessary Hash keys to all my Hub, Link and Satellite tables. The target environment for my Data Vault would be SQL Azure database and I decided to use a built-in crc32 function of the Mapping Data Flow to calculate hash keys (HK) of my business data sourcing keys and composite hash keys of satellite tables attributes (HDIFF).
Data Vault is somewhere on my list of things to learn. It’s not at the top of the list, but that’s not a slight against it.
