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

A definition of a Network database model Network database model is a hierarchical structure created to represent complex relation-ships more effectively than the hierarchical model‚ to improve database performance standard. Network database generally implement the set relationships by means of pointers that directly address the location of a record on the disk. This gives excellent retrieval performance Advantages of the network database model * Capability to handle more relationship types:
