“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.
“Data Quality Techniques is a standout contribution to modern data management, offering a clear and practical bridge between abstract data quality concepts and measurable, real-world implementation. With its structured approach, from definition to operationalization to quantification, it equips organizations to embed data quality as a governed, auditable capability.
“Dan Myers’ book Data Quality Techniques is a well-written and much needed text for data professionals and students alike. All too often, data quality concepts are discussed assuming that the reader can easily understand and correctly apply them. However, in both my academic and professional practice I find this not to be the case. This is why I am especially impressed with how each data quality concept presented in this book is also illuminated with understandable, practical examples.
“What Success Looks Like With Open DQ Repository”

Unfortunately, due to the intangible nature of data and poor record keeping within organizations this argument has been difficult to support.
Case Studies using the Conformed Dimensions of Data Quality (CDDQ)
The CDDQ offers a framework for organizing training, data quality projects, programs and data quality benchmarks. On this page we'll provide these examples over time.
For a number of years now, every time I play Battleship with my son, I've thought about how that game offers so many examples of Integrity relating to data quality. As is the objective of this blog, we'll use fun everyday topics to learn about data quality. We'll use a very common table-game and explain how it illustrates the importance of connectedness and for that matter how you can ensure you have an argument-free game between your kids.
Recently, when flying Southwest, I needed to reset my password. I wouldn’t have thought Data Quality applied to such a simple task, but of course they rejected my new password. I always use a password generator to create strong passwords. By default, I create all new passwords with a decent length including all three categories (letters with mixed case, numbers and Special Characters). So when I submitted my password I was prompted with the following error.
