Refer to the Level Zero data flow diagram below and the CWM case in responding to 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. Which of the following is most likely to be the name of Process 1.0?

Data flow diagrams can be used in which of the following steps of the systems development life cycle: (i) requirements analysis, (ii) design, (iii) implementation.

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.In a data flow diagram of the case, "previously completed works" are most likely to be represented with a:

Consider the following case as you respond to the next problem: The Festival Theatre produces twelve plays per year.Patrons can buy tickets for a single play; alternatively, they can purchase a season pass for either three plays or six plays.Three-play passes offer a 10% discount from the prices of single tickets; six-play passes, a 25% discount.Since most patrons live within 30 miles of the theatre, all ticket sales are done at the box office only.The theatre has an "open seating" plan, so patrons do not reserve a specific seat at any performance.Single-play purchases must be paid for in cash; season passes can be paid for with cash or major credit card.The Festival Theatre deposits all its cash receipts in the bank daily.Generate field names for the patron table, sales table and the sales/play table.

Both systems flowcharts and data flow diagrams can be used to document accounting information systems.Explain two similarities of and two differences between the methods.

Determine which of the following statements are: (a) correct for systems flowcharts only, (b) correct for data flow diagrams only, (c) correct for both or (d) correct for neither.1) Can be prepared using information technology tools 2) Clearly specifies responsibility for business processes 3) Commonly thought of as the one best way to represent an AIS 4) Incorporates verb phrases to label processes 5) Labels data flows between processes 6) May span multiple pages 7) Processes can be represented with different types of symbols 8) Represents processes with a single symbol type 9) Should be uncluttered and easy to read 10) Uses a symbol to represent a database
