Morgan Chase, Credit Suisse, Standard and Poor’s, AIG, Oppenheimer Funds, IBM, and Achieve3000. Additionally, Wayne has taught IIST (International Institute of Software Testing) courses on data warehouse, ETL, and data integration testing. He continues to lead numerous ETL testing and coaching projects on a consulting basis. You can contact him at wyaddow@gmail.com.
Data warehousing, integrations, and migrations are continually gaining importance as organizations attempt to transform the modern data explosion into insights that improve the customer experience and provide an edge against competition. However, data quality issues at various stages of ETLs are a major challenge to the rapid development and implementation of data integration solutions.
Many researchers have contributed to an understanding of data quality problems, collectively identifying general causes during these steps of data integration planning and execution:
- Schema design and modeling
- Data source profiling
- Data staging and ETLs
- Data transformations, cleansing, and enrichment
- Data reporting
The PDF that’s available below outlines the types of tests that this research found to identify data deficiencies across 8 data quality dimensions: accuracy, completeness, conformity, consistency, integrity, precision, timeliness, and uniqueness. I hope this information will help developers and others working on data integration solutions to expose and stop data deficiencies before moving to release.
