denormalisatie
Sign in to saveDenormalization is a strategy used on a previously-normalized database to increase performance. In computing, denormalization is the process of trying to improve the read performance of a database, at the expense of losing some write performance, by adding redundant copies of data or by grouping data. It is often motivated by performance or scalability in relational database software needing to carry out very large numbers of read operations. Denormalization differs from the unnormalized form in that denormalization benefits can only be fully realized on a data model that is otherwise normaliz

Denormaliseren is het intentioneel gedeeltelijk terugdraaien van de normalisatie van een gegevensmodel. Denormalisatie geeft de mogelijkheid het DBMS te dwingen gegevens bij elkaar, of juist apart van elkaar op te slaan. Vooral in datawarehouse-omgevingen wordt denormalisatie toegepast om de hoeveelheid disktoegang (Input/Output, kortweg I/O) te beperken.
