A slowly changing dimension is a dimension which's attributes can change over time.

If you want to know more (and there is quite a lot more Laughing

), please google on it. You'll find plenty.

hi babu,

Slowly Changing Dimensions

This applies to cases where the attribute for a record varies over time.

There are in general three ways to solve this type of problem, and they are categorized as follows:

Type 1: The new record replaces the original record. No trace of the old record exists.

Type 2: A new record is added into the customer dimension table. Therefore, the customer is treated essentially as two people.

Type 3: The original record is modified to reflect the change.

Regards
Ashok
