Table population & scanning jobs (Vantage 6.10)

I want to find out what tables get populated from the data collection
module when people clock in and out of jobs.

I need this information becasue I want to see if I can create
something that works with a barcode scanner more easily then what
Epicor provided. Namely because I want to start using hand held bar
code scanning computers instead of desk top computers. Easier
portability.

Thanks,
Tiony
