Can 2 different user run 2 database on Smabapos at a time

the main purpose is to have independent user based sale report and when they end the work poriod their reports are printed.
i know i can use custom reports but currently its having the formatting issue

so

for Manager i set database A
for Cashier set database B
using rdp Cashier can access his terminal while Manager is using his terminal

correct?

i thought i would face problem coz only one instance of samba can run
