Subject: RE: Simple Boolean Query Proposal.
Message text written by Krishna Sankar > Hi, This looks simple enough to implement - an implementer could even translate this to a SQL if they want it. David, did you produce any artifacts out of the NIST (query) work you mention in this e-mail ? On a related note, Matt, are you of the opinion that the regrep facilitate with basic/core query building blocks/primitives and the vendors can choose to implement adaptors (OQL,SQL,XML-Query) over those primitives ? cheers< >>>>>>>>>>>>>>>>>> Krishna, Thanks for the note. Yes in the Smithsonian implementation we were generating both automatic SQL and Btrieve queries directly off the one boolean query. We even managed a rudimentary query optimizer by looking for indexed columns and priority columns on the backend. Amazing what you can achieve with simple thoughts. I like Matt's thoughts too - and maybe we can quickly meld these ideas together and come up with a draft DTD to try out? I have a document that I was referring to from 4 months ago. I'll post it somewhere on a URL in the morning. I probably ought to quickly visit on it first and pull out stuff that's been deprecated - or just make a summary doc' on the simple query stuff alone. There was a lot of clutter in the original doc' as it was intended for general brainstorming off. DW.
