Remote Update ONCE a day

Hi all, Two days ago I was requested to make a proyect for a non-profit company, and I'm doing the drwaings for the databases and programming which I will use. This company wants to run the program in a PC which will not hold the main DB (which will will at HQ), but they also not need the new information in real time. What I don't know, if there's a way for me to install two programs and two DBs and had them updated let's say once a day using PC-ANYWARE or internet. I think maybe the one way to do this, is by making the HQ computer, download a file which holds the las 24 hours changes to the working DB. Is it possible for me to make PHP update the working DB and also reflect those changes into a Text file? I hope there's a better way that I haven't tink of yet. Does anyone knows this? Thanx in advance, Cesar Aracena caracena@infovia.com.ar Neuquen, Argentina
