Database normalization rules
Database Normalization in SQL with Examples – SQLServerCentral
FILE NORMALIZATION. Normal forms are theoretically based rules that help assure that databases can be maintained effectively. Placing tables into 3rd or higher normal form also gives a set of guidelines for breaking a set of attributes into a family of tables.

Thus, the multimedia database designer needs more sophisticated guidelines and tools to be able to understand the degree of normalization that guarantees the right compromise with respect to performances and correctness of results for each specific application context.

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. Although we discussed several levels of normal forms, this lab focuses on 1st Normal Form ...

Normalization is an important technique to design databases. To understand the process of normalization, consider a small example. We want to build a database for a small video rental store. We begin by thinking about who will be using the database and identifying what data they will need. Consider the situation of the checkout clerks.

Emphasize why normalization is important to stable database design with the relational, and then present a concise description of the various normal forms and the normalization process. Discuss some of the anomalies that arise when merging relations, and how to apply the principles we have learned to address these anomalies.
