Data scientists & the data warehouse team-building success

by

Data-Scientist-Tech-200Whether you are a CIO, data architect, or a data management professional, it is imperative to understand the different approaches, attitudes and needs of the next generation of data warehouse consumers. Traditional data warehouse users include reporting teams, BI teams (who created reports for the rest of the company), statisticians and others. In the past few years, this has been rapidly changing with the new roles of data scientists, the rise of Data Enthusiasts and the burgeoning population of Accidental Analysts. In Part 1 of this series, we focus on successful collaboration between data scientists and data warehouse teams.

Data scientists have been with us for many years. However, the moniker “data scientist” is a recent change. The same role existed (and still exists) with titles such as statisticians, mathematicians, computer scientists or systems analysts; however, having one of these alternate titles doesn’t necessarily imply that one is a data scientist, although a wide range of techniques may be used by both groups.

Traditional training for people now in data science focused on

Tableau futures—seamless access to your data

by

From the 2013 Tableau Customer Conference!

Seamless Access to the Data—coming in Tableau 8.1 and 8.2

Nothing else matters if you can’t get your data into Tableau. This was a common refrain I have said for quite some time, Tableau is irrelevant if regular business people can’t figure out how to get the data into the product. In fact, it is a very frustrating experience.

Tableau states that cleaning, integrating and reshaping your data should be available as visual operations. You shouldn’t need to learn SQL to manage it.

A new data connection interface was demoed. Earlier this year, I contributed to the vision and feature debates for this area as part of a talented team of people at Tableau. This team included Jun K, Dan C, Jock M, Chris S, Richard and several other great people. Here’s an example flow:

1) You have some data about bike rentals.  It’s in Excel or a text file and looks like this.  A bit rough-column names in all caps, start_time is a text field and some other important data isn’t in this file.

A brief history—Freakalytics and Tableau—since 2008

by

Stephen and I are frequently asked the story of why we wrote the first book endorsed by Tableau Software and how we launched their original, in-person training program back in 2009. In fact, we have been asked about this so many times, I decided it would be worthwhile to share the details.

2008
Stephen first discovered Tableau Software while working at Netflix. He was so impressed with the visual analytic capabilities of the product that after working with it for a couple of years, he approached the executives at Tableau about writing the first book on Tableau, which was still a tiny company at the time. They were excited about the idea so we met with CEO Christian Chabot, CDO and Co-founder Chris Stolte and several other executives to discuss the book content.

July 2009
Stephen completed and published the first edition of Rapid Graphs with Tableau Software just in time for the Tableau Customer Conference in Seattle. Marc Rueter, now a Senior Director at Tableau and Technical Reviewer of the book, wrote

“A great work- this is going to be a much-loved book.”
