Public Appearances

28th – 29th Sept 2016 Zurich, Switzerland: . I will be speaking at Trivadis’ annual event, this year called “Database Development and Performance Days” and consisting of two streams. My topics will be: “Just Don’t Do It” – examples of optimising your code by avoiding the work you didn’t need to do, and “Indexing” – a discussion of the benefits we hope to get from indexes (B-tree and Bitmap), why we don’t always get then, and what it costs to try.
17th – 21st Oct 2016 Slovenia and Croatia: . I’ve been asked to speak at the Slovenian and Croatian user group events which occur back to back over the week of 17th October. I’ll be presenting “Just Don’t Do It” and a short version of “Interpreting Parallel Execution Plans” for both events.
5th – 7th Dec 2016 Birmingham, UK: I’ll be giving three presentation at UKOUG Tech 16.

  • Tues 6th 12:35 – Cost Based Optimizer – the panel session (with Neil Chandler and Martin Widlake acting as MCs)
  • Tues 6th 16:50 – Indexing and the Impact of New Technologies
  • Wed 7th  9:00 – All about B-tree and Bitmaps – a masterclass (2 hours) on indexes
  • Wed 7th 11:30 – I’ve been asked to moderate the round-table on the Cost Based Optimizer

I’m also on the standby list if there’s a cancellation that needs a substitute, but it’s for a two-hour session so there’s less chance of it being needed than a standard session: Interpreting Parallel Execution Plans – a masterclass that starts where typical presentations on reading serial execution plans end.

Please email me questions for the panel session at Tech16@jlcomp.demon.co.uk

  1. Hi Jonathan, is there a plan for any online event? That would be very useful to attend virually.

    • Orausern,

      I’m working on rewriting my day-long seminar on Execution plans; should be ready early Feb, to be broadcast in 4 separate sessions so you don’t have to listen to the whole thing in one go.
