Produktbeschreibungen

Amazon.de

The premise of Improving Data Warehouse and Business Information Quality is 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

Written by an internationally recognized expert in information quality improvement, Improving Data Warehouse and Business Information Quality arms you with a comprehensive set of tools and techniques for ensuring data quality both in source databases and the data warehouse. With the help of best-practices case studies, Larry English fills you in on:
* How and when to measure information quality.
* How to measure the business costs of poor quality information.
* How to select the right information quality tools for your environment.
* How to reengineer and cleanse data to improve the information product before it reaches your data warehouse.

2.0 von 5 Sternen Good information but tedious reading 27. Oktober 1999
Von Ein Kunde
Format:Taschenbuch
The author presents information and advice that is not readily available anywhere else.
Unfortunately, the book is so boring that it is doubtful that it will actually get read by many people outside the data administration community.
The problems with the book are many. It is the most repetitious book I ever read. The author should learn about tautologies because they constantly appear in the book. Also, there are too many bulleted lists, step-by-step programs, and diagrams that may be okay for a spoken presentation but make for distracting and dull reading. Finally, there are many "do an effective...." and "conduct a thorough..." type of statements. The author should just say what a thorough or effective (or the like) practice is.
One more aspect of this book is really bothersome. It is titled as if it is a data warehousing book. But references to data warehouses seem to appear as afterthoughts. Most of the book is relevant to designers of transaction processing systems. And the author never lets us in as to why, if we follow the principles in the book, we need a data warehouse.
Finally, this book mostly discusses structured information. At this time when information technology professionals are "discovering" that most information used is unstructured, the author's orientation is shortsighted.

5.0 von 5 Sternen THE CORPORATE INFORMATION QUALITY JOURNEY 21. September 1999
Von Ein Kunde
Format:Taschenbuch
Anyone who has had the pleasure of hearing Larry English speak on the subject of Information Quality will know that he is one of the leading and most passionate advocates of the need for high information quality as the foundation of a profitable business.
As we enter the age of eBusiness,companies can no longer hide their information quality problems from their customers. Successful eBusiness companies will be those who recognise and manage information as their key strategic asset.
This book is essential reading for all who are serious about profitable survival in the information age. Larry writes as he speaks - with knowledge, conviction and pragmatism. This book should be read by all who are concerned about information, whether senior corporate executives, business information managers or IT specialists.
The book is full of practical answers to problems and is of great value whether you are leading a major cross-enterprise information improvement drive or trying to enhance quality within a specific data warehouse or system.
Strongly recommended.

5.0 von 5 Sternen A 'must-have' book for every IRM professional 29. Oktober 1999
Von Karen
Format:Taschenbuch
The chapters on estimating your organization's cost of having non-quality data make this book a requirement for every Information Resource Management professional's book shelf.
Larry English is one of the few authors in the industry to show you how to work the numbers when it comes to data quality. While others drop hints at why quality is good, Mr. English tells us how to collect the data and how to calculate the true costs of sub-standard data management practices.
As our profession matures we will be called upon to make more explicit business cases for what we recommend to senior management -- Larry has some great methods for us to use. This will save us months of having to figure it out for ourselves.

5.0 von 5 Sternen The best book I've ever read on Information Quality 21. März 1999
Von Andy
Format:Taschenbuch
This book takes the reader from understanding and applying principles of Quality Management to a step-by-step guide for implementing a quality improvement program.
I liked the organization and writing style of this well-referenced text. I found the diagrams and tables very helpful.
In the introduction, the author states that the text is a "concept book, a textbook, a reference book, and a practitioner's guide." At first I didn't believe it. Now that I've finished the text, I believe every word.
When I read the "Author's Warranty" (and how many books do you know come with a warranty?), I had an inkling that this would be a good book.
I was wrong. This is a GREAT book!

Format:Taschenbuch
Tackling the issue of information quality is undoubtedly one of the most significant challenges of businesses today. Larry's book provides clear, concise guidance on how to recognize information quality issues and determine and quantify their true business impact. He also outlines a common sense approach on how to effectively improve the integrity of business information and recognize the return on investment in sound quality improvement initiatives. As a consultant specializing in Information Stewardship and Quality, I find this book my most valued reference. From a professional standpoint, I have to borrow the motto of American Express Credit Card Company, I "Don't leave home without it!"
