We often find that the terms data warehouse (DWH) testing and ETL Testing are used interchangeably as if they were the same when discussing business intelligence quality assurance.
The importance of data storage rises further as businesses realize the advantages of data-driven, business-decision making. Data warehouse performance, scalability, and reliability are all bolstered by an ETL process that can consistently extract, transform, cleanse, and load data from source systems during normal operation.
Data quality issues are typically introduced at an early point in the process, at one of the several warehouse development phases. Rapid development and deployment schedules might increase the likelihood of flaws being introduced unintentionally into fast-track projects.
