In what cases would you denormalize tables in your database?

Denormalize is the mechanism is carried out by addition of the redundant bits in the already normalized database.The data is attached in the form of attributes,adding new tables.

This technique is used in the case of previously normalized data collection which requires improvement in the performance by reducing the errors.The improvement is made by making database readable ,adding  group of data in redundant form etc.

When data is to be retrieved quickly then also denormalization is used as by grouping or collecting information into a single table.

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.
