Hi All, I need your help to find out the most appropriate place (in the Derby folder structure) to locate the new tool, that will be developed in this summer as the GSoC project of mine.
The Visualizer tool: Derby-4587 (https://issues.apache.org/jira/browse/DERBY-4587) Description: Quite frequently, users of Derby have troubles in comprehending the steps followed by the optimizer when it translates a query into a query plan, and details such as time to execute, resource utilization at each step of the query plan. There are low-level features in Derby which capture this information and record it, such as logQueryPlan, and the XPLAIN tables, so this project will lead to a development of a new tool which can process the query plan and execution statistics information and present it in a more comprehensible fashion i.e. a graphical interpretation of the query plan. You can find information about the design at http://wiki.apache.org/db-derby/Nirmal/Derby-4587-%20Design%20Details Your suggestions are highly appreciated. Thank you very much. -- Best Regards, Nirmal C.S.Nirmal J. Fernando Department of Computer Science & Engineering, Faculty of Engineering, University of Moratuwa, Sri Lanka.
