On Multi-Active Satellites in Data Vault
In this article I describe why you could use multi active satellites in your Data Vault, why you probably shouldn't in most cases and how you can do it if you have to: use a document satellite design to prevent granularity issues down the road.
On Links
In this article I’m discussing only links representing transactions. I deliberately exclude links which represent relations (i.e. master data relations = giving context to an object like the link between a city and a commune). I highlight the challenges of the existing design and propose to always use a hub to define the granularity of a link.
