Exam 8: Data Flow Diagramming

A systems flowchart contains two process symbols, one manual process symbol and one predefined process symbol.If that same system were depicted with a leveled set of data flow diagrams, how many circles would the context diagram have?

Consider the following illustration as you respond to the questions: A relational database of the process depicted would include the "perform initial screening" table.Which of the following statements about that table is most true?

Which of the following statements about systems flowcharts and data flow diagrams is most true?

Which of the following statements about systems flowcharts and data flow diagrams is most true?

"Diagram Y" is:

Which of the following statements about systems flowcharts and data flow diagrams is most true?

Consider the following illustration as you respond to the questions: "Diagram X" is:

Please refer to the following case as you answer the question: Comprehensive Waste Management (CWM) provides trash hauling services for several communities in southern California.When a new client wants to establish service, the client calls the company's main office on the phone.A CWM employee collects the following information from the client: name, street address, city, state, ZIP code, area code, telephone number, e-mail address.The employee gives the new client information regarding regular weekly service dates, special services provided by the company, fees and billing procedures.CWM bills its clients every two months in advance of the service; for example, bills are sent to clients at the beginning of January for the months of January and February.Initially, CWM does all its billing manually; they send out paper bills and collect payment from clients via check.Once service is established, a client can create an online account; the online account provides an option for paperless billing and a separate option for charging a credit card rather than paying with a mailed check.To create an online account, the client creates login credentials (user name and password); they provide their CWM account number (provided on the invoice) and relevant credit card data (type of card, name, billing address, and security code).CWM's database uses the account number to look up the client's original information, then merges the new information with it.CWM stores clients' information electronically.The database file would be represented in a data flow diagram with a(n):

Please refer to the following short case as you respond to the question: A painter accepts orders for original works from customers in person or via the Internet.Based on the order, the painter creates an initial sketch, which must be approved by the customer; the customer may make changes to the initial sketch.After customer approval, the painter selects appropriate materials and gives the customer a price quote.If the customer accepts the price quote, the painter creates the original work; if not, the project is abandoned.The painter stores data about customers, previous orders and previously completed works in an electronic database.Data flow diagrams incorporate four symbols.Which of the following pairs of items would be represented with the same symbol in a DFD of the case?

Booksellers of Bufluffia is a small, independent bookstore that both publishes and sells very specialized titles.They currently have about 50 clients; they publish and sell 30 different books at present.The company's management has asked you to create database tables to support their operations.Suppose the database includes four tables: clients, inventory, sales and sales/inventory.In which table(s) would you expect to see a field labeled "client ID?"
