Restaurant Management System - RMS

What if there was a restaurant management system for managers which helped manage the restaurant? Normally restaurant or fast food managers use spreadsheets to make shift schedules, track orders. But this is inefficient. This program will do all that but in a more efficient manner. It will create shifts using manager inputs, it will also track orders, and employees Furthermore, this program can only be used by the manager and no other employee. I call it RMS, restaurant management system, just like POS point sales system but much better and not just for sales.

I have 1 year of python experience, and have been learning SQL for about 2 weeks. No the program uses only what I created other than the tabulate, sqlite3, and pathlib libraries.

Usually I like to create a flowchart to organize what's going to happen. With the limited time, I didn't have that luxury. I also didn't know how to display all the data in a nice table, so I had to research that, I ended up using tabulate. Other than that, my computer was stuck at updating 21% and my project was submitted late and some parts are incomplete unfortunately.
