This document discusses database normalization. It begins by defining normalization as organizing database fields and tables to minimize redundancy. It then discusses different normal forms - First Normal Form (1NF), Second Normal Form (2NF), and Third Normal Form (3NF). For each form, it provides an example table to illustrate the concept. The goal of normalization is to isolate data and define relationships between tables to reduce anomalies from modification, deletion and insertion of data.
