The normal forms are applicable to individual tables; to say that an entire database is in normal form n is to say that all of its tables are in normal form n. Newcomers to database design sometimes suppose that normalization proceeds in an iterative fashion, i.e. a 1NF design is first normalized to 2NF, then to 3NF, and so on.

https://info.5y1.org/normal-form-database-design_1_9c9de7.html
Third Normal Form. Database theory has developed over the years. We will NOT study this history! We will simply look at the current preferred method of database design, which is to create “relational” databases with tables in “third normal form.” The databases are called “relational” because of the relationships between the primary ...

Normalizing Your Database: First Normal Form (1NF) 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 ...

Each normal form represents an increasingly stringent set of rules; that is, each normal form assumes that the requirements of the preceding forms have been met. Many relational database designers feel that, if their tables are in third normal form, most common design problems have been addressed.

Normalization is a process that is incorporated in every step of Database Design. The following steps ask you to double check the design to ensure that the database will be in Normal Form. First Normal Form. OVERVIEW. First normal form eliminates repeating fields in individual tables, for example Class1, Class2, Class3 in a Student table.

Normal forms are a progression of these rules. Each successive normal form achieves a better database design than the previous form did. Although we discussed several levels of normal forms, this lab focuses on 1st Normal Form (1NF), and Boyce-Codd Normal Form (BCNF).
