My understanding is that Business Data Vault
is built from Raw Data Vault
i.e ( Hubs
). I have seen variations or situations, where some BDV tables ( not sure about the usage of these tables at this time) are pulling data from Staging Data Vault
i.e Staging tables instead of RDV ? Is this an acceptable design
\ implementation or does this break the fundamentals\best practices
of DV and what are the implications ?
In my mind, i was thinking this can lead to creating multiple sources for same information and defeats the purpose of single source of truth.
