Normalization reduces data redundancy from "summary" of SQL and Relational Theory by C. Date
Normalization is a technique that is widely used in the design of relational databases. One of the key benefits of normalization is that it helps reduce data redundancy. Redundancy refers to the situation where the same piece of data is stored in multiple places within a database. When data redundancy occurs, it can lead to several problems. For example, it can make it more difficult to maintain data consistency, as any changes to the data must be made in multiple locations. This increases the likelihood of errors and inconsistencies creeping into the database. Normalization helps address this issue by ...
