Most difficult data modeling questions

Most difficult data modeling questions

At Data Modeling Zone Europe, I will be teaching a full day Advanced Data Modeling Challenges Workshop.

I always love to end these workshops by asking a few difficult data modeling questions that I have been asked over the last 12 months.

For example, at last year’s event, here are three questions that were asked:

  1. Explain blockchain with a simple use case (other than Bitcoin) and discuss how it will impact data modelers and business analysts.
  2. Can a CDM contain attributes?
  3. Do our current data modeling notations hamper or help with model NoSQL? Explain and provide a solution.

What questions have you faced this past year that you would like answered? (Maybe I will ask your questions at DMZ in November!)
