Data Model Question for dealing with many Multi-Value data columns. Each data column has multiple values with ";" seperators.
Should I unroll the different columns values into their own tables with a relationship key back to the one original Dim record? In other words create a star schema.
Or leave them and use Measures with SEARCH / SUBSTITUTE functions to select the Dim records?
Which is easier to visualize?
TIA
maybe you can try to split to rows in pq

Thanks. I know how to split and manipulate the data into various tables. I have no problems with Power Query / M and DAX measures.
My question is still from a design standpoint, should I create the different tables and link them back to the original row,
-or-
just leave the semicolon values alone and use a SEARCH measure to to get the row?
i think you duplicate the column and the new column after splitting can still link back to the original column
