Testing a data warehouse involves validating the data required and the data sources, data profiling, data quality & performance, data transformation rules, reviewing the data dictionary, validating source to target mapping, validation of ETL/DW architecture, validation of Data Model (dimentional modeling, normalized approach), indexing & partitioning, error loging, exceptional handling, OLAP & cube testing and report testing.

Data wiping is the process of logically removing data from a read/write medium so that it can no longer be read. It can be performed internally by booting a PC from a CD or network. It is a nondestructive process that enables the medium to be safely reused without loss of storage capacity or leakage of data.
