What is De-normalization?
De-normalization is the process of attempting to optimize the performance of a database by adding redundant data.
De-normalization is the process of attempting to optimize the performance of a database by adding redundant data.
It is sometimes necessary because current DBMSs implement the relational model poorly.
A true relational DBMS would allow for a fully normalized database at the logical level,
while providing physical storage of data that is tuned for high performance.
De-normalization is a technique to move from higher to lower normal forms of database modeling in order to speed up database acces.
