How to Finally Get Self-Service ... By Ditching the Star Schema

Ahmed will dive into why self-service so frequently fails: it's a data modeling problem.

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.
