I am having trouble figuring out how to do the diagram 0 for the is assignment and I don't where to start.

For this assignment you are to complete a Diagram O from the information provided. Below is the context Diagram of a Sales Order System where it will serve as your starting point for this assignment. You are to use the information from the context Diagram and create the next lower-level diagram (Diagram 0) which will explode the Sales Order System process and illustrate more details as to how the system works. Update Employee Managers New Employee Employees Product and Category Employee List Sales order system Order Invoice Vendor and Product-vendor Managers are also Employees; Employees can enter Customer data and orders. Customer Customers Order and Order-line Order and Order-line means the order itself. Order-line is another way to say all the line items on the order. So, think of it as you are looking at a sales receipt from Walmart. The order is information about the store, date, time, receipt number, cashier ID, etc. Order-line are the product listed on the receipt that you ordered. So, if you purchased a bike, some apples, and a light bulb on the order, then you will have 3 order-lines. Vendor and Product-vendor inflow from Managers represent Manager entity deciding and providing information regarding which vendor (and their products) the store will carry. The Product and Category on the context diagram means Employees are providing the information regarding what products from what category in the store's catalog that the Employees is able to see/select while helping customers through the Sales Order System
