Hi all,

I was recently reading about the Unified Star Schema and the Puppini Bridge. I’m curious whether anyone here has experience with it and what their thoughts are.

TIA

    Haven’t heard of this before, but I’ve basically implemented it in my own work and it’s worked out great.

    I believe implementing facts and dimensions via a star schema is still very useful and serves as a great modeling format, however there’s definitely times where my downstream users need a single OBT type table. Ex. CSMs use a tool fed by data warehouse but none of them know SQL, so we feed a single “bridges” table to them that includes everything.

    One interesting flaw with my implementation I’ve found, my users are looking for all the data under the sun, and I wasn’t previously prepared originally and had to add a lot of columns over time. This grew into a massive mess that needs to be remodeled via multiple OBT type bridge tables. It’s very easy to just throw everything in these tables and lose all structure.
