> The explain plan is the key tool DBAs use to optimize queries. Just like full
> screen editing is needed for complex queries, it is essential that the
> explain plan be compact enough to represent complex queries. The current
> visual explain plan only allows a few operators to be displayed at once on
> the screen.
> As a DBA I should be able to see a moderately complex query (~ 15 operators)
> on a single screen.
> As a DBA the explain plan should focus on the key information, namely
> statistics and costs.
> As a DBA I should be able to drill down into an operator for additional
> information, if needed.
> The explain plan should update to reflect changes to tuning parameters.
> It should be possible to view the "explain analyze" information in the
> explain plan
