Normalization of Database Tables Database Tables and Normalization * Normalization is a process for assigning attributes to entities. It reduces data redundancies and helps eliminate the data anomalies. * Normalization works through a series of stages called normal forms: * First normal form (1NF) * Second normal form (2NF) * Third normal form (3NF) * Fourth normal form (4NF) * The highest level of normalization is not always desirable. * The Need
