Project Title
Banking System
Introduction
The project involves the bank arrival and scheduling mechanism for the clients. Different clients like Golden customers and normal customers are given the precedence level. Golden customer is given high priority. The project can handle 80 normal and 19 golden clients. Whenever a person enters in the bank, he gets a token a number is allotted to him which is between 01~80 for normal clients and 81~99 for golden customers. We have two counters for customers if there is a golden customer he will be served first. We need four register to store values of token. Two are for Golden customers and remaining two are for Normal customer. We named them as Normal Customer Register (NCR) which store value of last token issued to normal customers. Golden Customer Register (GCR) which store value of last token issued to golden customers. Counter Normal Customer Register (CNCR) which store value of last normal customer attended by bank staff. Counter Golden Customer Register (CGCR) which store value of last golden customer attended by bank staff.
