I completely missed this discussion question!

The simplest way is to look at the MultipleReadProperty.py where you provide a list of points to read and when it's done, zip up the data and send it someplace. This particular sample runs once and exits, so you could run this an a "cron job" at some interval or you could modify it to loop around and read the points again.

It should be pretty simple to extract a point list from a database, when you get to multiple intervals it gets a little harder, when you want to take advantage of Read-Property-Multiple it gets interesting. The MultipleReadPropertyHammer.py application sends multiple concurrent reads to the device at the same time which can quickly overwhelm a device or the network if it's a field bus like MS/TP or ARCNET.
