Improving Data Warehouse and Business Information Quality: Methods for Reducing Costs and Increasing Profits
The premise ofImproving Data Warehouse and Business Information Qualityis that the quality of information stored in a database is just as measurable as the quality of the cars that come off an assembly line. Furthermore, database managers can take steps to ensure that their databases collect the best possible information.This is a dense book, loaded with management jargon, statistical analysis, and complicated flow diagrams. You won't succeed in skimming casually through it, and you will probably get more out of the book if you have some experience with quantitative management techniques.Regardless, this book makes excellent reading for those taking the holistic approach to database design, in which a good database considers where the information comes from, how it is used, and what results come from that use. English covers some methods for extracting information from various sources--through surveys and other methods--before launching into an elaborate discussion of information-quality metrics.--David Wall
