If a table is not properly normalized and have data redundancy then it will not only eat up extra memory space but will also make it difficult to handle and update the database, without facing data loss. Normalize the data: normalization is the process of organizing the data in the tables to minimize data redundancy and improve data integrity. the goal of normalization is to create tables that are in the first normal form (1nf), second normal form (2nf), third normal form (3nf), and so on. Introduction to dbms dbms is a software that enables users to define, create, maintain, and control access to the database. Data independence is defined as a property of dbms that helps you to change the database schema at one level without requiring changing the schema at the next higher level.
