I'm very, very new to ModelBuilder.
I have a database that's being continuously updated with new addresses. I'm trying to set up ModelBuilder such that, each time I log in to my computer, ArcGIS geocodes any new addresses that have appeared since I last logged in. So I suppose that, with each log in, I'd have the computer scan over the previous log-in's list and geocode any thing that's new.
I've already figured out how to schedule running the model with each new log in, but how would I command ArcGIS to do this comparison?
