Prof. Dr. Dirk Schieborn

AM3 Data Analysis and Machine Learning · Reutlingen University

A database is a pot full of tables, connected by keys. An index finds one row among 100 million in three steps, and SQL only says what you want to know.

NewOct 18, 2026 · 5 chapters

An explainer film in five chapters, made from a real lecture: why a course on machine learning starts with tables, what relation, attribute and tuple mean, how keys connect tables like joints, how a database finds one row among 100 million in three steps, and why SQL only says what should come out. Pause anywhere and ask.
