The most important thing I recommend to cope with large data volumes is partitioning. If you apply a smart partitioning scheme to the data model and the ETL process, performance of the DWH and the Data Marts can be dramatically improved. Hope that helps Frank Kuldeep,

Can you post few article/tips on hierarchical data model and datawarehouse design on very large OLTP schema say 1000 GB Nice post. it actually helps a lot.
