Explore the processes involved in the Order System based on the given data.

Final answer:

The context and level 1 data flow diagram of an order system reflect how various entities (Customer, Sales Rep, Warehouse, Bank, Accounting) interact with the system. The diagrams elaborate on the processes of filling orders, creating invoices, and applying payments.

Explanation:

Context and Level 1 Data Flow Diagram of an Order System

A contextual data flow diagram for an order system would include entities such as the Customer, Sales Rep, Warehouse, Bank, and Accounting. Each entity interacts with the system in various ways, typically through sending and receiving information. The Customer, for example, sends an Order and Payment to the system.

The Level 1 Data Flow Diagram further elaborates the operations of the system. The 'Fill Order' process encompasses the receipt of an order from the customer, sending of a picking list to the warehouse, and sending a rejection notice to the customer if necessary. The 'Create Invoice' process takes the completed order from the warehouse and provides the invoice to the customer. Finally, the 'Apply Payment' process takes the payment from the customer, updates the data storage 'Account Receivable,' and sends necessary information to Sales Rep, Bank, and Accounting.

In conclusion, the order system's context and level 1 data flow diagram present a detailed view of the workflow from the perspective of different entities involved.
