It's rare enough to have a single unbiased, objective non-vendor-sponsored, statistically valid snapshot of what is really happening in the business intelligence (BI) industry. However, with the recent publication of The OLAP Survey 4, we now have a series of studies conducted using a consistent methodology, which lets us look at trends.

As with previous editions of The OLAP Survey, this fourth edition included the DM Review reader panel; therefore, some of you may have participated in the latest survey. However, this time we decided to try to obtain a more international flavor to the sample overall, so we teamed up with a German industry analyst organization to get a much clearer picture of the situation in German-speaking countries. The questionnaire was fully translated into German, and far more people in continental Europe were included in the study.
