Connecting Multiple Tables to The Same ID Column

Hi, I am about to build a data model connecting one Lookup table to three different Fact production tables with the same MasterData_ID column in each. In planning the relationship, am I able to link the MasterData_ID column of the Lookup table to each of the three respective production tables’ MasterData_ID columns so they they all relate (talk) to each other?

In other words, can I run ‘three’ one-to-many relationships from the one Lookup table (MasterData_ID) to the three production tables (MasterData_ID)? Would this be a logical configuration? Thanks.

Hi @Dplex,

That’s exactly how it works your Dimension/Lookup table filters will propagate through the 1:* relationship to all associated fact tables. A best practice is to hide all Key fields in those fact tables so they can’t be selected by mistake.

@Greg created a series on best practices, this one refers to modelling. I’d suggest to check out the entire series you can find it in the Best Practices playlist on the eDNA YouTube Channel.

As well as this structured course, it has several chapters on modelling.

I hope this is helpful
