Answer / naga bhushanam.banglore
Slowly changing dimensions(SCD) is the type of dimensions
which changes with respect to time or peeriod.
Fo s ex: there is an table which has objects like
Country City Employeeid ddress .
Here for example the say the employee of employee id say
e23321 is presently in Hyderabad after a month he is re-
located in Banglore than we can say the address dimension
is SCD w.r.t. time
We have 3 types of SCDs:
SCD-1
SCD-2
SCD-3
SCD-1:where no historical data is not maintained only
present data is maintained
SCD-2:Where complete historic + presentl data is maintained
SCD-3:Where one time historic(say previous) data+ current
data is maintained

Answer / mrs.narmatha
Slowly changing dimension applies to some cases where
attribute for a record varies over time.
For example a person called narmatha lived in one place
(india). So the original entry in the customer lookup table
like : customer id :100 name: narmatha country:India
At a later the person moved to UK
How should XYZ Inc. now modify its customer table to
reflect this change? This is the "Slowly Changing
Dimension" problem.
