Using Python to ‘Wrangle’ Your Messy Data

 or How to Organize Your Comic Book Collection Based on Issue Popularity

In addition to being a product manager at Rittman Mead, I consider myself to be a nerd of the highest order.  My love of comic books, fantasy, sci-fi and general geekery began long before the word ‘Stark’ had anything to do with Robert Downey Jr or memes about the impending winter.  As such, any chance to incorporate my hobbies into my work is a (more...)

Becky’s BI Apps Corner: OBIA install Perl Script Patching and troubleshooting when they fail.

During a recent project installing Oracle BI Applications, I became much better acquainted with OPatch, Oracle’s standard tool for managing application patches. By acquainted, I mean how to troubleshoot when OPatch patching fails. Since, at last count, there are around 50 patches total for Oracle BI Applications 11.1.1.9.2, the first patching attempt may not apply all patches successfully. There are any number of reasons for a failure, like an extra slash (more...)

The best OBIEE 12c feature that you’re probably not using.

With the release of OBIEE 12c we got a number of interesting new features on the front-end.  We’re all talking about the cleaner look-and-feel, Visual Analyzer, and the ability to create data-mashups, etc.

While all this is incredibly useful, it’s one of the small changes you don’t hear about that’s truly got me excited.  I can’t tell you how thrilled I am that we can finally save a column back to the web catalog (more...)

OBIEE12c – Three Months In, What’s the Verdict?

I’m over in Redwood Shores, California this week for the BIWA Summit 2016 conference where I’ll be speaking about BI and analytics development on Oracle’s database and Hadoop platforms.
