References for ETL Design Patterns talk

4/4 San Diego SQL BI User Group:

Here are those references I mentioned in my 4/4 talk on ETL Design Patterns.  Lots of good content in here.  And for those that haven't studied Project REAL yet, definitely recommend giving it a look.  Even though it is a few years old, still very relevant for many implementations.

Considerations for High Volume ETL Using SSIS (2008)

CodePlex SSIS components

Pareto Chart with PowerPivot

A Pareto Chart can be a powerful visualization to help you apply the 80/20 rule.  This viz focuses attention on the ~20% of the universe (customers, products, etc.) that often contributes 80% of the desired outcomes (sales, conversions, etc.).  Allowing you to focus your efforts on the ones that deliver the most important results (the items that are even with and to the left of where the running total crosses the target 80%).

Building a viz like this is insanely easy in Excel with PowerPivot.  Especially in Excel2013.

Analyzing Events using a Time dimension in PowerPivot / AS Tabular

Who knew Delorean's topped out at 88 MPH...
This is a follow-up post to one I did a little while back on Time dimensions in PowerPivot and AS Tabular (here's a link to that one).  I want to walk through building a model with that Time dimension.  And then use the model to analyze event data and explore for patterns by different date and time slices.

Excel 2013 & PowerPivot: Multiple Copies of a Calculated Measure for use with "Show Values As" Analysis

I've been working with Excel 2013 more and more recently, and have to say I'm impressed with all of the enhancements the product team pulled together.  Especially in the BI area.  All the hard work up in Redmond is definitely paying off.  PowerPivot is continuing to mature and become more smoothly integrated with Excel.  And the Excel analytics features keep getting better.  Not to mention the addition of PowerView.

I wanted to do a few posts and share my thoughts on some of the things that I really like and think are particularly useful when working with PowerPivot models and building visualizations in Excel.  Lots of improvements that make it easier and faster to get from raw data to insights.  And allow users / analysts to spend less time and less clicks building and more time analyzing and exploring.

So for this first one, I'll focus on the ability to use multiple copies of the same PowerPivot calculated measure in a given pivot table or pivot chart.  This is something I really needed early last year on a dashboard effort, so when I saw this in Excel2013, I was stoked to say the least.
