The Type Of De-normalization?

Hello Dear,

Please Tel Me What Is The Type Of De-normalization ?

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. ... Denormalization should not be confused with Unnormalized form.

In two dimensional information system we use the normalization but in decision support systems we use de-normalization

Denormalization is a database optimization technique where we add redundant data in the database to get rid of the complex join operations. This is done to speed up database access speed. Denormalization is done after normalization for improving the performance of the database.

In a traditional normalized database, we store data in separate logical tables and attempt to minimize redundant data. We may strive to have only one copy of each piece of data in database.

Denormalization 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.

Denormalization is a database optimization technique in which we add redundant data to one or more tables. ... For example, in a normalized database, we might have a Courses table and a Teachers table. Each entry in Courses would store the teacherID for a Course but not the teacherName.

Denormalization is a database optimization technique in which we add redundant data to one or more tables. This can help us avoid expensive joins in relational databases. In traditional normalized databases, we store data in separate logical tables and try to minimize redundant data.
