Reg: Datawarehouse records delete problem

Hi

Iam using SQl server 2005 Integration Service to transfer the data from Source Data Base to Datawarehouse DB. Here my main problem is after trnsfering the data from main Data Base to datawarehouse DB. If any records is delete from main database, how can we delete same records in Datawarehouse DB. If I want to delete any record in the datawarehouse that record mapped with some other tables [Foriegn Keys].

Regards,

Hanu

You should review the Project REAL ETL best practices (http://download.microsoft.com/download/4/1/f/41f09116-19b3-40fe-9d54-d1e9b7af9e82/ProjectREAL_ETLDP.doc) - the section on Slowly Changing Dimensions maybe helpful.
