Latest Presentations Now Available

I’ve updated this blog’s Presentations page to include all presentations that I’ve done at Hotsos Symposium 2015, IOUG COLLABORATE15, and the Chicago and Dallas Oracle User Group functions over the past few months. When you can spare a few moments, you’ll be able to review my slide shows that:

  • Explain how’s new In-Memory Column Store features can make an incredible difference for query performance – especially when running a star schema query in a data warehouse environment
  • Demonstrate how’s new Attribute Clustering and Zone Mapping features help alleviate unnecessary physical I/O by ordering data in the most appropriate order, especially for data warehouse application workloads
  • Illustrate how the Oracle database optimizer uses histograms in Oracle 12c, and how two new histograms – Top Frequency and Hybrid histograms – resolve issues with extremely popular and barely popular values
