This document discusses database normalization through three forms (1NF, 2NF, 3NF) to organize data efficiently and reduce data anomalies. 1NF focuses on removing repeating groups. 2NF removes attributes that are dependent on only part of a composite primary key. 3NF removes attributes dependent on non-key attributes to eliminate transitive dependencies. The goal is to isolate data so changes to one set do not affect others.
