ETL Testing for Effective Data Warehousing
The high cost of creating a Data Warehouse must be justified by equally high returns in terms of benefits to the business, or this can be an expensive waste of time. If you do go down the Data Warehouse route, however, quality assurance is paramount to ensure you get the result that you want.
Data Migration Testing or ETL is essential to ensure that any data transferred from diverse sources to the warehouse happens without loss of information. Testing should also ensure that there is full compliance to validity checks and transfer rules.
Testing must be able to find any issues with the source data early on and also cover any other inconsistencies. ETL testing should also be continuous to ensure that every process, from extraction to transformation is working perfectly.
