What do we test in data warehouse testing?

BI/data warehouse testing involves the creation, execution, and maintenance of tests that automatically verify data quality across all BI/DW stages (including the reporting layer). Data integrity can be compromised when data is created, integrated, moved, or transformed.

What are the five stages of ETL testing?

ETL testing is performed in five stages:

  • Identifying data sources and requirements.
  • Data acquisition.
  • Implement business logic and Dimensional Modeling.
  • Build and populate data.
  • Build Reports.

What is ETL Testing Tools?

ETL testing is a software testing process which is done to ensure that the data that has been loaded from a source to the destination after business transformation is accurate. It also involves the verification of data at various middle stages that are being used between source and destination.

What is difference between database testing and ETL testing?

Both ETL testing and database testing involve data validation, but they are not the same….Database Testing.

Function Database Testing ETL Testing
Database Type It is normally used in OLTP systems It is applied to OLAP systems
Data Type Normalized data with more joins De-normalized data with less joins, more indexes, and aggregations.
