The document defines various forms of database normalization from 1NF to 5NF. It provides examples to illustrate each normalization form and how a database table can be decomposed to satisfy the given normalization form. The goal of normalization is to organize data to eliminate anomalies like data redundancy, insertion anomalies, update anomalies and deletion anomalies. Each successive normalization form builds upon the previous ones and introduces additional constraints to further reduce anomalies and improve data integrity.
