Tough SQL Analysis

With this presentation I’d like to touch quite delicate spot of Db2 knowledge – tough SQLs.
I suppose most of us aware how to improve one table SQL – that’s a must. But sometimes things got worse, SQLs could be much more complicated and normal technics are not enough.
How to approach them – that’s an idea for the presentation.
