Accepted Answer

A

Question 3

A circle in a data flow diagram represents:

Accepted Answer

A circle in a data flow diagram represents a business process. This is because it shows an activity or operation being performed within the system. A data flow, external entity, and database are represented by other shapes on the diagram.

Question 4

Which of the following is most likely to be represented with a rectangle in a data flow diagram?

Accepted Answer

A rectangle in a data flow diagram typically represents a process or activity, and a bank would often be represented as a process in a financial system. The customer file and deposited checks are likely to be represented by other shapes such as a document or data store.

Question 5

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?

Accepted Answer

In Data Flow Diagrams (DFDs), both data stores and data flows are represented with unique symbols. However, the question asks for pairs of items that would be represented with the same symbol. "Initial sketch" and "price quote" are both examples of data or information that flows between processes (e.g., between the painter and the customer), making them both data flows.

Question 6

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, "create initial sketch" is most likely to be represented with a:

Accepted Answer

The answer of Please refer to the following short case...

Question 7

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

Accepted Answer

Processes are numbered in a data flow diagram, but not in a flowchart. In a data flow diagram, processes are represented by circles and are labeled with a number. In a flowchart, processes are represented by symbols such as rectangles and are usually labeled with a brief description of the process.

Question 8

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

Accepted Answer

The number of columns in a systems flowchart or the number of process symbols does not directly dictate the levels in data flow diagrams or the maximum number of process symbols in them. These are different tools for modeling systems and their complexity does not translate directly in such a manner.

Question 9

A circle in a data flow diagram may be labeled similarly to which shape in a systems flowchart?

Accepted Answer

In a systems flowchart, a rectangle is used to represent a process, similar to how a circle is used in a data flow diagram to represent a process or transformation of data.

Question 10

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:

Accepted Answer

In a data flow diagram (DFD), a set of parallel lines typically represents a data store or a place where data is held. "Previously completed works" would be stored in an electronic database, making the set of parallel lines the correct representation.

Question 11

Which of the following is most likely to be represented with a set of parallel lines in a data flow diagram?

Accepted Answer

A set of parallel lines in a data flow diagram typically represents a data store or a file. Therefore, the option that represents a file - "Customer file" - is most likely to be represented with a set of parallel lines. The other options represent processes and would not typically be represented with parallel lines.

Question 12

A line in a data flow diagram represents:

Accepted Answer

A line in a data flow diagram represents a data flow, which is the movement of data between processes, external entities, and data stores.

Question 13

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?

Accepted Answer

The context diagram in a leveled set of data flow diagrams only contains one circle, which represents the entire system being analyzed. The number and type of process symbols in a systems flowchart do not affect the number of circles in a context diagram.

Question 14

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.Which of the following pairs an element from the case with an appropriate symbol in a data flow diagram of the case?

Accepted Answer

In a data flow diagram (DFD), processes are represented by circles (or ovals). The action of selecting appropriate materials is a process, making option C the correct choice.

Question 15

A line in a data flow diagram may be labeled similarly to which shape in a systems flowchart?

Accepted Answer

The answer of A line in a data flow diagram...

Question 16

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

Accepted Answer

Both lines are used in both, but they represent different things and circles are used in both, but they represent different things are true.

Question 17

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.A data flow diagram of the case contains three items: create initial sketch, initial sketch, finalize sketch.How are those three items likely to be represented in the data flow diagram?

Question 19

Pablo had been asked by his supervisor to create a document explaining the process of paying an invoice.If he wants to create a diagram that focuses on data, he could create:

Accepted Answer

A data flow diagram focuses on the movement of data within a system, which would be most appropriate for explaining the process of paying an invoice. A systems flowchart, on the other hand, focuses on the flow of activities and decisions within a system. Therefore, a data flow diagram would be the best choice.
