------------------------------------------
Hi Bryan,
I read http://db.apache.org/derby/docs/dev/getstart/ to get an idea about how
Derby works, because it's the most appropriate start in my view.
But if you can direct me to some guides on developing Derby, that would be
really great !! I've downloaded, both bin & src of the final release of Derby
and also I've checked out Derby Trunk through SVN repository, but not quite
sure about how can I modify and compile/build the source code.
Thanks !!
Regards,
Nirmal

> Project: Derby
> Issue Type: Improvement
> Components: SQL, Tools
> Reporter: Bryan Pendleton
> Assignee: Bryan Pendleton
>
> I think it would be great to see some work in the area of tools for helping
> with the analysis of complex query execution. Quite frequently, users of
> Derby have trouble comprehending (a) how their query is being translated
> into a query plan by the optimizer, and (b) what the execution-time resource
> usage of the various parts of the query is.
> There are low-level features in Derby which capture this information and
> record it, such as logQueryPlan, and the XPLAIN tables, but there is a lot
> of opportunity for designing higher-level tools which can process the query
> plan and execution statistics information and present it in a more
> comprehensible fashion.
