Global Bike customers can email in orders to the order processing center where clerks record orders for processing. As the clerk is entering data the computer updates the applicable customer and inventory master data. The computer displays the completed order and the clerk reviews the order (assume there are no discrepancies). The computer then updates the sales order master record, updates the inventory master data to allocate inventory to the sales order, prints a picking ticket in the warehouse, and send an order confirmation to the customer via registered email.

Required:

a. Prepare a table of entities and activities.

b. Prepare a context and logical data flow diagram. Hint: The context diagram of this billing system shows two external entities: customers and the shipping department.

c. Prepare a systems flowchart (hint: the systems flowchart will have three swim lanes, the last one depicting the warehouse).
