“I wholeheartedly recommend Data Quality Techniques. In his explanation of the Conformed Dimensions, Dan Myers provides the "ABC Company" data model, allowing readers to learn data profiling using actual data, along with the SQL structure for the "Open Data Quality Repository" to store the results. By delving deeply into specific measurement techniques, he brilliantly bridges the gap between data quality theory and the realities of practice. It is a must-read for all practitioners taking on the challenge of data quality improvement.”
