VIDEO: Aster Tango - SQL-MR/GR Scripting Tool

Writing SQL-MR and SQL-GR statements is made much easier by a tool I wrote while on vacation.  As an Aster Data Scientist I needed a tool that would enable me to focus on the 'WHAT' and not the 'HOW!'  I needed a tool to write the code for me.   So I wrote Aster Tango.

Your Math Is All Wrong: Flipping The 80/20 Rule For Analytics

I was deep into a presentation at a major retailer. In the darkened room, a lone hand shot up. “John, we spend 80% of our time on data load and prep. Only 20% is used to produce analytics. We don’t like that ratio.”

The speaker was right. About 80% of the analytics process is spent on data preparation and loading. Numerous examples come to mind. I remember a project for an auto insurance company using telematics and driver behavior. The one-off code to prepare the data took three days…
