This document discusses normal forms in database management systems (DBMS). It introduces normal forms as rules for structuring relational databases to reduce data redundancy and improve integrity. The document describes first normal form (1NF), second normal form (2NF), and third normal form (3NF), explaining how each builds on the previous form to further eliminate redundancy. Some benefits of normal forms are that they improve data integrity, reduce redundancy to save storage space, and simplify querying.
