A while ago I added some information on Derby's SQL language system to the wiki
http://wiki.apache.org/db-derby/LanguageSystem This was taken from an internal IBM Cloudscape presentation on the same topic. I added as a wiki because it seems an ideal candidate where anyone could add more information. So feel free to add information as you learn about any part of the system, so others can benefit. Any form of information is good: - questions, vague ideas of how something works, just be clear if you're unsure if you information is correct or not - links to e-mail threads or other information - links to the javadoc - writeups on various areas See this more as a collection of information related to the SQL langauge system, not a perfect architecture document, so as I say, any information is good. Seems like Army and Satheesh have been working in the optimizer, so maybe anything they learnt there could be added. I will find time to add information to the code generation section since I've been working there. Thanks, Dan.
