u told its based on clients requirment only.then wat boss?
thats the answer.if he needs only one record we wil load
only one record. if he need 599999 record to be in target
we wil do that. its based on how we create dimension and
fact in data warehoue. ultimately al our data has to help
the client to see the needed data and to analyse and to
take strategic decisions from it.
