Adams, Inc. customers mail their orders to the Adams customer service center where clerks open the orders and review them for accuracy. The clerks then key orders into the computer. As the clerk is entering data the computer populates the order input screen with data from the applicable customer and inventory master data. The computer displays the completed order and the clerk reviews the order (assume there are no discrepancies) and then accepts the order (selects the "save" icon on the input screen). The computer then creates a sales order master record, updates the inventory master data to allocate inventory to the sales order, prints a picking ticket in the warehouse, and displays the sales order number to the customer service center clerk. The clerk then reads this number to the customer. Required: a. Prepare an annotated table of entities and activities. Indicate on this table the groupings-bubble numbers and bubble titles-to be used in preparing the level 0 logical data flow diagram. b. Prepare a logical data flow diagram (level 0 only). The context diagram of this billing system shows two external entities: customers and the shipping department. c. Prepare a systems flowchart.
