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

5.what is slowly changing dimension ?..

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.
