Ahmed will dive into why self-service so frequently fails: it's a data modeling problem. The current approach of using a star schema as a data model fails to support adhoc questions because it requires predefined JOINS. Ahmed will present the activity schema, an alternative data model that requires no joins or foreign keys. A single 10-column table (with a single, standard structure) can model any data for analytics and answer any question. Narrator uses the Activity Schema to enable a new era of self-service where anyone can answer any question in under 10 minutes.
