[pilot-db-list] Modifications to DB

[Scott W. <swa...@my...>]

Hi,

	I've been playing around with the DB source, and am thinking about
making some modifications.  In particular, I'm very interested in adding
calculated fields.  I'm hoping I can get a number of different features
from them:

	1.  calculate intra-record values (all data from a single record)
	2.  calculate inter-record values (data from 2 or more records)
	3.  calculate global values (e.g. summary information)

	I have made some progress on an old version of db, but before
I sync up with the new version, I was hoping to get some feedback.

	-is this a feature that anyone else is particularly interested in?
	-is this a reasonable time in db's life to begin this addition?
	-assuming the 2 above are true, what steps are necessary to
		help ensure that my code will be 'easy' to integrate
		with db in the future?


	in addition there obviously a number of important design decisions
that will need to be made. If there is relative support for this type of
modification I would input before I get too far into it.

	thanks,

	-Scott
