Dear Readers,

Every year DM Review conducts an independent readership study to assess the overall effectiveness of our editorial content, to obtain the current status of our readers' business intelligence and data warehousing implementations, and to select the best products based on quality and overall value to the enterprise. I am pleased to provide you with some of the highlights of our most recent readership study.

With regard to editorial, the most valuable topic areas covered are:

1) Data warehouse design, administration and management,

2) DSS and data marts, and

3) Data quality and acquisition.

The readership study also revealed that Bill Inmon is the most popular columnist followed by Larry English, Doug Hackney, Susan Osterfelt and James Martin. (The Peppers and Rogers column started after this survey was completed.) We also learned that the average reader spends more than one hour reading each issue of DM Review and, on average, more than three people read each issue sent to a subscriber.

With regard to the current state of business intelligence/data warehousing projects, over 50 percent of our readers are in the early stages of the data warehouse process. These stages include initial planning (26 percent), prototype or pilot (15 percent) and design (9 percent). The typical data warehouse has 485 users, 533GB of data and eight subject areas. The typical data mart is under 50GB (74 percent), although 2 percent have data marts greater than a terabyte. The biggest challenges of implementing a data warehousing project were: business rule analysis (40 percent), managing management expectations (36 percent), managing end-user expectations (35 percent), business/data modeling (32 percent), data acquisition (28 percent), data quality (26 percent) and ROI justification (22 percent).

To find out who you, our readers, consider to have the best products, please refer to page 40 for this year's DM Review Readership Award winners. Congratulations to all of them!

Be sure to contact me if you have any questions, comments or suggestions. Just send an e-mail to rpowell@dmreview.com .

Thanks to all of you who participated in this survey and, Thanks for reading DM Review!
