I recently made an ERD for my laundry POS project I would highly appreciate it if someone could take a look at it. This was a struggle for me because I had never tried doing my laundry in a laundry shop before and each laundry shop in our area has a different system. I’m trying to create a somewhat standard that everyone can easily follow and hopefully can be scalable for future improvements. Is my current implementation viable enough? can you suggest some improvements?
