Announcing the Winners of the 2019 Oracle Dev Gym Championship for Database Design

Chris Saxon
Developer Advocate

On Thursday 13 February, 37 plucky contestants took part in the annual Database Design Championships over on Oracle Dev Gym.

This competition tested the players' knowledge of Oracle Database 19c in a series of five quizzes. These covered JSON_equal, hybrid partitioned tables, histograms, constraint optimizations and COUNT DISTINCT in materialized views.

The results are now in, so it's time to announce the winners!

  1. Iudith Mentzel (86% correct)
  2. Maxim Borunov (80% correct)
  3. Stelios Vlasopoulos (78% correct)

These three were clear of the chasing pack, with several players getting 74% correct. And huge congratulations to to Iudith for taking the top spot for the third year in a row!

And, once again, a well-earned thanks to Elic, our quiz-reviewer supreme. His behind the scenes work ensured high-quality quizzes.
