The Challenge

Most companies and their C-level executives are using Business Intelligence (BI) and Analytics to make strategic decisions in the hope of gaining a strategic advantage in a tough business landscape.

BI and Analytics software typically sit on top of data warehouses and data marts that are gathering data from other applications, databases, big data stores, web sites and other data sources. According to Gartner, the average company will lose, on average, $8.2 million annually due to bad data.

So, comprehensive testing of data at every point throughout the ETL (Extract, Transform, Load) process is becoming increasingly important as more data is being collected, analyzed and acted upon.

The Biggest Issues with Data Warehouse Testing

  • Data warehouse/ETL testing requires SQL programming. This is an issue since the majority of testers are manual testers with limited SQL coding skills, leaving a much smaller pool of resources to perform data testing.

  • Comparison of the data is typically done by extracting data from source data stores and the target data warehouse using SQL Editors and then dumping results to Excel to “stare and compare” (also known as sampling), meaning verifying the data by viewing or “eyeballing” the results. This is a huge problem because 1 test query can return as much as 100 million rows with 200 columns, making it impossible to find data errors.
