Growing Use Cases for Learning R and Python

By Fern Halper, VP Research, Advanced Analytics

There was a time when choosing a programming language for data analysis had essentially no choice at all. The tools were few and they were usually developed and maintained by individual corporations that, though they ensured a reliable level of quality, could sometimes be quite difficult to work with and slow to fix bugs or innovate with new features. The landscape has changed, though.

Some People Call Me the Data Wrangler, Some Call Me the Gangster of Prep

By Meighan Berberich, President, TDWI

Data prep. Wonderful, terrible data prep. According to John Akred of Silicon Valley Data Science, “it’s a law of nature that 80% of data science” is data prep. Although our surveys average closer to 60%, even that’s an awful lot of time to spend not analyzing data, interpreting results, and delivering business value—the real purpose of data science.

By Chris Adamson, Founder and BI Specialist, Oakton Software LLC

Technological advances have enabled a breathtaking expansion in the breadth of our BI and analytic solutions. On the surface, many of these technologies appear to threaten the relevance of models in general, and of the dimensional model in particular.

The Role of Centralization and Self-Service in a Successful Data Hub

A hub should centralize governance, standards, and other data controls, plus provide self-service data access and data prep for a wide range of user types.

By Philip Russom, Senior Research Director for Data Management, TDWI

I recently spoke in a webinar run by Informatica Corporation, sharing the stage with Informatica’s Scott Hedrick and Ron van Bruchem, a business architect at Rabobank. We three had an interactive conversation where we discussed the technology and business requirements of data hubs, as faced today by data management professionals and the organizations they serve. There’s a lot to say about data hubs, but we focused on the roles played by centralization and self-service, because these are two of the most pressing requirements. Please allow me to summarize my portion of the webinar.
