external entity

data store

internal entity

Boundary

18.

1 point

Which data flow diagram shows what activities the system is performing without having to specify how, where, or by whom the activities are accomplished?

context diagram

physical data flow diagram

systems flowchart

logical data flow diagram

19.

1 point

Data flow labels in context diagrams usually describe:

what the data are (physical labels)

the nature of the data (logical labels)

to whom the data are being transmitted (identity labels)

where the data are being sent (directional labels)

20.

1 point

In which of the following data flow diagrams does the bubble symbol represent a process and not the entire system?

context diagram

physical data flow diagram

logical data flow diagram

systems flowchart

21.

1 point

In a logical data flow diagram (DFD) for a cash receipts system, each of the following labels might appear in a bubble except:

Cashier

capture cash receipt

prepare deposit

record customer payment

22.

1 point

The data flows in a logical data flow diagram (DFD) show:

how the data are transmitted

where the data are transmitted

the nature of the data being transmitted

who transmits the data

23.

1 point

When two data flow diagrams (DFDs) have equivalent external data flows, we say that the two data flow diagrams are:

congruent

similar

balanced

equal

24.

1 point

A process in which successive layers of data flow diagrams (DFDs) are constructed by "exploding" the bubbles on a less detailed DFD to show more detailed data flows is called:

top-down partitioning

serial expansion

balanced construction

expanded data flows

25.

1 point

Which of the following statements related to the construction of data flow diagrams (DFDs) is false?

The level 0 diagram is the next level down from the context diagram.

If the level 0 diagram has one arrow going into bubble number 1.0 and two arrows leaving bubble number 1.0, then diagram 1.0 will show one arrow entering and two arrows leaving.

Sources and destinations are depicted by parallel horizontal lines, between which the name of the entity is shown.

Arrows represent a pathway for data.

26.

1 point

A systems flowchart varies from a data flow diagram (DFD) because it:

only represents the information system

only represents the operations system

only represents the management system

represents the management system, the operations system, and the information system

only automated activites

activities that retrieve, transform, and file data
