Teradata Geospatial Extensions: a Case Study in User-Defined Types
Posted by Robert Morton on October 6, 2008
Many database systems are highly extensible through user-defined types (UDTs), methods (UDMs) and functions (UDFs). Database system vendors often provide UDFs to assist users with migrating from a competitor's DBMS to their own. But UDTs, UDFs and UDMs also provide domain-specific functionality, as seen in Teradata's Geospatial Extensions. Tableau offers a simple, powerful way to exploit these DBMS extensions that can enhance the analytical expressiveness of your visualizations.

Posted by Elissa Fink on September 24, 2008
Great news for those of you who are into analytical mapping. Today, Tableau Software released version 4.1 which offers many new enhancements including the ability to use WMS (Web Map Service) map images as background maps for your data visualizations in Tableau Desktop. I personally like some of the satellite maps we've found. 4.1 also offers other enhancements, including Server performance improvements and Active Directory improvements.
Do You Say Coke, Soda or Pop? A Map Visualization Shows Your Likely Answer
Posted by Elissa Fink on August 25, 2008
A good Tableau customer, Michael Cristiani of Market Intelligence Group, recently sent us a challenge. He had discovered a dataset for which people were surveyed about their choice of words for their preferred icy, carbonated beverage. Specifically, did they use the word “coke”, “soda”, “pop” or some other word? There were nice maps on the site but with Tableau 4.0’s new mapping capabilities, he wanted to know what we could do with the data. Given that I was in a hotel room when I read about this, I decided to give it a go with Tableau 4.0 (beats renting a bad movie) and came up with some interesting results.
Seattle Walkability
Posted by Robert Morton on August 21, 2008
I recently relocated to Seattle to join Tableau Software, and as I searched for a place to live I realized that I could dramatically reduce my dependence on driving. I used WalkScore.com to find a neighborhood with great access to restaurants, stores and a vibrant community. The attached Tableau visualization shows how lucky I am to live and work in Fremont, the Seattle neighborhood affectionately referred to as "The Center of the Universe!"
