Answer Posted / sivaraman (gasc)
Denormalization is the process of attempting to optimize
the performance of a database by adding redundant data or
by grouping data. In some cases, denormalization helps
cover up the inefficiencies inherent in relational database
software. A relational normalized database imposes a heavy
access load over physical storage of data even if it is
well tuned for high performance
