Database normalization or database normalisation (see spelling differences) is the process of structuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity. It was first proposed by British computer scientist Edgar … Ver mais A basic objective of the first normal form defined by Codd in 1970 was to permit data to be queried and manipulated using a "universal data sub-language" grounded in first-order logic. An example of such a language is Ver mais • Denormalization • Database refactoring • Lossless join decomposition Ver mais • Date, C. J. (1999), An Introduction to Database Systems (8th ed.).
