Pretty Pictures of BI: Tableau
There is an emerging genre of BI tools built specifically for business users to perform visual data discovery. The user interfaces are designed to be intuitive and the features simple. These software products are meant to require little if any training. Architecturally, many provide in-memory analysis for high performance.
Of course, these "exploration" tools are also not intended to be full enterprise BI platforms. Instead, they are complementary to more robust products. You will not replace your existing BI products (SAP Business Objects, IBM Cognos, IBI WebFOCUS, MicroStrategy, etc.) with the limited scope of visualization software but you might consider supplementing them.
While QlikTech's revenue reporting for QlikView appears much higher than that of Tableau's, the job statistics imply that Tableau is in much higher demand.
Tableau to be the Winner?
As part of a Department of Defense initiative, PhD candidate Chris Stolte created a "Visual Query Language" to explore large multi-dimensional databases. As luck would have it, Stolte's university mentor was Pat Hanrahan, a founding employee of Pixar.
Together, they created what has been called “a kind of high powered, highly visual Excel,” which is a really good way of explaining the innovative software product. One of their first interested partners was Essbase, which makes sense. A common user interface for the Essbase cube was Excel, and Tableau was a nice next-generation version of that.
Tableau is the type of visual analytics software that Microsoft itself should have added to Excel.
The full version of Tableau Desktop allows access to a variety of databases and publishing capabilities while the "Personal Edition" works only with desktop flat files and spreadsheets. You can easily download copies of Tableau Desktop for one or two thousand US dollars per user license (for Personal and Professional Editions, respectively).
Why Not Tableau?
I will address Tableau's enterprise web-based and mobile usage at a later date but for departmental desktop usage, there are few hurdles to using Tableau.
If you have "spreadsheet jockeys" trying to perform data visualization with just Excel, then Tableau is a perfect holiday gift.
If your organization has a formal software development group anxious to control BI, however, then handing out desktop tools may not be a popular option. Controlling one version of the truth becomes harder when business users create their own BI fiefdoms.But Business Intelligence is a strange animal and IT organizations often seem unable to control it. Few want to be the BI zookeeper. If so, responsibility for quality BI moves over to the business.
