What was the largest database / dataset you analyzed? [347 votes]|
We note that more than twice as many analysts participated in 2012 poll (347 people) than in a similar 2011 Poll: Largest Dataset analyzed/ data mined, (148 people).
Among significant differences, we observe that the peak of the distribution shifted from
1.1-10 GB in 2011 to 11-100 GB in 2012.
A smaller percentage have reported the largest dataset in 1.1-10 GB range in 2012 (16.4%) as compared to 2011 (19.7%), and a larger percentage have reported the largest dataset of 11-100 GB range (21.6%) as compared to 2011 (17.7%).
Note: In 2011 the maximum range given in the poll was 1 PB and over, so no direct comparison for Petabyte range is possible between 2011 and 2012 results.
The median answer in 2012 can be estimated to be in 20-40 GB range, compared to 10-20 GB range median answer in 2011.
The percentage of analysts with experience in the upper range of datasets (over 100 GB) has remained around 35% - same as in 2011, but this could be due to larger participation in 2012 poll. In 2010, about 32% of respondents worked with 100GB and larger DB.
Regional breakdown (below) shows that almost every region now has a median in 11-100 GB range.
