Normalization is the process of applying a series of rules to ensure that your database achieves optimal structure. Normal forms are a progression of these rules. Each successive normal form achieves a better database design than the previous form did. ... Based on the sample data …

PROCESS OF DATA NORMALIZATION. 1. ELIMINATE REPEATING GROUPS. Make a separate table for each set of related attributes and give each table a primary key. 2. ELIMINATE REDUNDANT DATA. If an attribute depends on only part of a multivalued key, remove it to a separate table. 3. ELIMINATE COLUMNS NOT DEPENDENT ON KEY

Data normalization is directly related to the business processes. The tables you design depend on the way the business is organized. First Normal Form. Now that we have a way of writing down our assumptions, it is relatively straightforward to separate the data into tables. The first step is to split out all repeating sections.

Last time, we explored the basic principles of database normalization. You learned how careful database design adhering to the rules of normalization can increase the efficiency and logical structure of your DBMS. In this article, we begin our look at the first of three major normal forms -- first normal form (otherwise known as 1NF).
