At XYZ company, a sales rep can be assigned to more than one customer. The sales rep can be put into the ERP system before serving customers (hint: this part is referring to a minimum cardinality). A customer is assisted by one and only one sales rep, and must be assigned to a sales rep. A customer can be put into the system before placing an order. A customer may place many orders, but a sales order comes from only one customer (i.e., customers do not share a sales order). An order contains at least one inventory item, but could contain many items. All items that XYZ keeps track of are not sold (some are used for maintenance of machines, etc.). An inventory item can he sold on more than one sales order. Sales orders are later invoiced. Multiple sales orders can be on one invoice and there may also be partial billings (e.g., sales order gets partially shipped and that shipment gets invoiced billed, then the remaining portion of the sales order gets shipped and subsequently billed on another invoice). The same applies for payments. Customers can make a partial payment (remittance) on their invoice(s), pay an invoice in full, or a single payment can be made to apply to multiple invoices. Summary of Crpw's Foot Notation One or Zero One and only One Zero or Many One or Many There are maximum and minimum cardinalities. - Maximum cardinality is the maximum number of occurrences of an entity [i in relation to another entity. These go on the outside of the line. Will be 1 or [ many. - Minimum cardinality is the minimum number of occurrences of an entity in relation to another entity. These go on the inside of the line. Will be 1 or 0 (simply means is an occurrence necessay/required) [?]
