Simple one terminal data base

Does anyone have a simple one terminal Restaurant Bar style data base, I can use to see how all this works? I get 20% of what to do then I fall apart. I can not set up a employee POS terminal where the employee starts work enters her cash (bank starting money)into the register then sets up for her shift with her name and password to the POS terminal. and after her shift completes she does her close out at the terminal with a cash sales report?

Of course, you can do these things. But my advice is to avoid using a pre-built database. It adds features you don’t need. You can find them by searching the forum.
