Question 6

Which of these represent a comprehensive picture of management, operations and information systems?
A) context diagram
B) logical data flow diagram
C) physical data flow diagram
D) systems flowchart

Accepted Answer

Systems flowchart represents a comprehensive picture of management, operations and information systems by showing the flow of inputs, processes, and outputs of a system. It includes various components such as data storage, decision points, and feedback loops, and helps in understanding the overall functioning and interactions of different parts of the system. Context diagram, logical data flow diagram, and physical data flow diagram are also important tools in systems analysis and design, but they do not provide as comprehensive a picture as a systems flowchart.

Question 7

System flowchart logic should:
A) flow from left to right
B) flow top to bottom
C) flow from bottom to top
D) a. and b. but minimize crossed lines and connectors

Accepted Answer

Option A and B are commonly used flowcharts but using both options together is more legible and clear. It's important to minimize crossed lines and connectors to avoid confusion. Therefore, the best choice(s) is option D.

Question 8

A(n) ______________________________ shows what activities the system is doing without specifying how, where or by whom the activities are accomplished.

Question 10

The following systems flowchart segment depicts a user's query of a data store to view information on a computer screen. Which statement is correct? 
A) The systems flowchart was created properly.
B) Only a single direction arrow should connect the data store symbol to the process query symbol.
C) The query input symbol should be a square.
D) The query input symbol should be in the computer column.

Accepted Answer

According to standard systems flowcharting conventions, only a single direction arrow should connect the data store symbol to the process query symbol. Therefore, option B is correct. Options A, C, and D are not relevant to the flowchart segment depicted.

Question 11

______________________________ are those persons, places, or things outside the system that send data to, or receive data from, the system.

Accepted Answer

The answer of ______________________________ are those persons, places, or things...

Question 12

In a data flow diagram (DFD), a(n) ______________________________ symbol depicts an entity or a process within which incoming data flows are transformed into outgoing data flows.

Accepted Answer

The answer of In a data flow diagram (DFD), a(n)...

Question 13

Examine the following context diagram and the related level 0 logical DFD. Which of the following statements is true? 
A) The diagrams are prepared correctly.
B) A context diagram must have a least two external entities.
C) The diagrams are not balanced.
D) None of the above are true.

Accepted Answer

The context diagram shows only one external entity, the customer. However, the level 0 DFD shows two external entities, the customer and the warehouse. This means that the diagrams are not balanced, and there is inconsistency between them.

Question 14

Bubbles are labelled with verbs in a ____________ data flow diagram.

Accepted Answer

The answer of Bubbles are labelled with verbs in a...

Question 15

Which of the following segments violates guidelines for creating systems flowcharts? a.
b.
c.
d.
A) Segment a.
B) Segment b.
C) Segment c.
D) Segment d.

Accepted Answer

The given segments are not visible, so it is not possible to determine which segment violates guidelines for creating system flowcharts.

Question 16

A(n) ______________________________ is the top-level, or least detailed, diagram of a system depicting the system and all its activities as a single bubble and showing the data flows into and out of the system and into and out of the external entities.

Accepted Answer

The answer of A(n) ______________________________ is the top-level, or least...

Question 17

When a transaction cannot be processed in a routine fashion because of an error or other processing problems, the transaction must be handled by a(n):
A) rejection routine
B) change report
C) exception and summary report
D) exception routine

Accepted Answer

When there is an error or processing problem with a transaction, it must be handled by an exception routine, which is specifically designed to handle exceptional cases that cannot be processed through routine procedures. Rejection routines, change reports, and exception and summary reports may be useful in certain contexts, but they are not designed to address every type of problem that may arise during transaction processing.

Question 18

A(n) ______________________________ is a person, place, or thing within the system that transforms data.

Accepted Answer

The answer of A(n) ______________________________ is a person, place, or...

Question 19

The following systems flowchart segment depicts a data entry clerk keying data from a source document into a business event data store. Which statement is correct? 
A) The systems flowchart was created properly.
B) The arrow between the computer process and the data store should be bi-directional.
C) The computer process should be shown in the computer column.
D) The second symbol in the data entry clerk column should be a square.

Accepted Answer

The computer process should be shown in the computer column, as it represents a computer process.

Question 20

The following is a jumbled list of the activities suggested in this text for drafting data flow diagrams (DFDs) for an existing system: 
I.	Prepare a table of entities and activities.
II.	Prepare an annotated table of entities and activities.
III.	Draw a physical data flow diagram.
IV.	Draw a logical data flow diagram.
V.	Draw a context diagram.
 The best sequence for undertaking these activities is:
A) I, II, V, III, IV
B) I, V, III, II, IV
C) II, I, III, V, IV
D) II, IV, III, I, V

Accepted Answer

The best sequence for undertaking these activities is to first prepare a table of entities and activities (I), then create a context diagram (V), draw a physical data flow diagram (III), and finally draw a logical data flow diagram (IV). To ensure clarity and consistency, it is also recommended to prepare an annotated table of entities and activities (II). Therefore, the correct sequence is I, V, III, II, IV. Option B lists these activities in the correct order.
