Description

The complete "self-help guide" to dramatically improving business data quality.

  • Why business data goes bad -- and exactly what you can do it about it.
  • Ten specific data quality improvement techniques you can start using today.
  • Dramatically enhance the ROI of any data warehousing, customer relationship, and knowledge management application!
Poor data quality hampers today's organizations in many ways: it makes data warehousing and knowledge management applications more expensive and less effective, presents major obstacles to e-Business transformation, slashes day-to-day employee productivity, and translates directly into poor strategic and tactical decisions. In this book, data expert Michael Brackett presents ten "bad habits" that lead to poor data -- and ten proven solutions that enable business managers to transform these bad habits into best practices. Data Resource Quality is organized around ten "bad habits" organizations have fallen into: habits that inevitably reduce data quality, waste resources, increase the cost of using and maintaining data resources, and compromise business strategies. In each case, Brackett shows how the "bad habits" evolved, and exactly how to replace them with best practices that can dramatically improve data quality, starting now. Along the way, Brackett demonstrates exactly how to implement a solid foundation for quality data -- an organization-wide, integrated, subject-oriented data architecture -- and then build a high-quality data resource within that architecture. For all IT managers, consultants, and application users -- in both large and small enterprises.

Michael H. Brackett retired as data resource coordinator for the State of Washington in 1996. He has 37 years of information technology experience, and has written five books on the topic of data resources, including Data Sharing Using a Common Data Architecture, and The Data Warehouse Challenge: Taming Data Chaos.
