ETL TESTING

• What is ETL Testing
• Much ETL testing today is done by SQL scripting
• or eyeballing of data on spreadsheets. These
• approaches to ETL testing are very time
• consuming, error-prone, and seldom provide
• complete test coverage.

ETL TESTING

• ETL stands for Extract-Transform-Load and it is a
  process of how data is loaded from the source
  system to the data warehouse.  Data is extracted
  from an OLTP database, transformed to match the
  data warehouse schema and loaded into the data
  warehouse database.  Many data warehouses also
  incorporate data from non-OLTP systems such as
  text files, legacy systems and spreadsheets.
