Experts,

I'm looking for input on ideas to keep in mind when planning and creating a MEDICAID data warehouse. This data will be used to help identify WASTE, FRAUD AND ABUSE.

Has anyone worked on this type of DW?

I'd be interested in hearing what you used for you BUS MATRIX concept.

What type of Fact(s) table(s) did you create, what DIMS did you create...etc..etc..

A sample STAR SCHEMA would be GREAT is you have one!

Thank

That's a quite a broad set of questions! I haven't done work specifically with Medicaid data. When I started on my first data mart back in 1999, I remember doing a lot of reading and head scratching. I used whatever version of Kimball's book was current at the time, and it answered a lot of questions like those you are posing. I don't think I could answer them well without writing a book of my own, and maybe not even then, but there should already be good contemporary books available.

The facts and dimensions you will use pertain to what you want to be able to query out of your system. You can go through a dimensional modeling process to help understand what they might be. You have choices and tradeoffs, based upon what data you have to query against and what questions you want to ask of it. I'm thinking that even if I could remember the dimensions and facts for the systems I created, or if I could find an old star schema, it wouldn't help you much because the data and intended uses would be very different.

When you get down to those specific choices and tradeoffs, in the modeling process, those are questions that might more readily be addressed here. Although we'll see what others have to say.

You'll want to provide more detailed requirements, as many experienced experts are going to avoid this 'Do my job for me' style of question, as we have no confidence when the question will be answered.

Thanks in advance.
