The Data Vault Handbook - Concepts and Applications

Reference Hubs and Satellites are preferred over standard Hubs and Satel- lites for modeling reference data due to their simplicity and efficiency. By hosting both the Reference Hub and Satellite with a readable code instead of a Hash Key, downstream joins become more straightforward, reducing query complexity and improving performance. 3.2.4. OTHER ENTITIES In addition to the core and derived entities discussed so far, the Data Vault model also includes other specialized entity types such as Same-as Links, Ef- fectivity Satellites, Exploration Links, and Compute Aggregate Links, among others. While we won’t get into the details of these entities in this guide, we encourage readers interested in exploring them further to consult the Re- sources section (Section 5) for more information.
