We are interested in measuring the quality of the data populated in our data warehouse. Based on different measurements (e.g., how many records were rejected), our idea is to create a global index, or a score that indicates the quality of the data within the data warehouse. Larry English's recent quality book provided us an excellent start. Are there other publications or works that have been performed, from which we may borrow some ideas?


Larissa Moss' Answer: Here are two more books you might find useful:

  1. Quality Information and Knowledge, by Kuan-Tsae Huang, Yang W. Lee and Richard Y. Wang, published by Prentice Hall, 1999, ISBN 0-13-010141-9. Chapter 4 might be of special interest to you, "Measure, Analyze and Improve IQ."
  2. The Data Warehouse Challenge, Taming Data Chaos by Michael H. Brackett, published by John Wiley & Sons, 1996, ISBN 0-471-12744-2.
