Question 2

Match each of the following terms with its description.
-Graphically representing the functions that capture, manipulate, store, and distribute data between a system and its environment and between components within a system
A)Gap analysis
B)Functional decomposition
C)Process modeling
D)Balancing
E)DFD completeness

Accepted Answer

Process modeling involves graphically representing the functions that capture, manipulate, store, and distribute data between a system and its environment and between components within a system. Gap analysis involves identifying the differences between current and desired states. Functional decomposition involves breaking a system into smaller, more manageable parts. Balancing involves ensuring that inputs and outputs are properly balanced in a system. DFD completeness involves ensuring that all necessary processes and data flows are included in a data flow diagram.

Question 3

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-A data flow cannot go directly back to the same process it leaves.

Accepted Answer

A data flow cannot go directly back to the same process it leaves, so it cannot be represented by the process symbol (A).

Question 7

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-A data flow to a data store means update.

Accepted Answer

A data flow to a data store indicates that data from a process is being stored in the data store, i.e., updating the data in the data store.

Question 8

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-A process must have both inputs and outputs.

Accepted Answer

Only a process symbol is required to have both inputs and outputs.

Question 11

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-A source/sink has a noun phrase label.

Accepted Answer

The answer of For each of the following statements, answer...

Question 12

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-There must be at least one other process that handles the data flow, produces some other data flow, and returns the original data flow to the beginning process.

Accepted Answer

Only the process symbol represents a specific condition that must be met in order to use it in a data flow diagram. The other symbols (data flow, source/sink, data store) can be used without the presence of another process, but a process must exist to handle and/or manipulate the data flow.

Question 13

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-A fork in a data flow means that exactly the same data go from a common location to two or more different processes, data stores, or sources/sinks.

Accepted Answer

A fork in a data flow occurs when the same data is sent from a single source to multiple locations or processes.

Question 14

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-The inputs to a process are different from the outputs of that process.

Accepted Answer

The symbol for process represents a specific action or operation that takes input data and produces output data. The other symbols (data flow, source/sink, and data store) do not represent actions themselves but instead represent the movement or storage of data within the system.

Question 15

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-A data flow has a verb phrase label.

Accepted Answer

A data flow symbol is used to represent the movement of data between two symbols (e.g. a process and a data store or a source/sink and a process). The symbol is labeled with a verb phrase to describe the nature of the data flow. Examples could include "Receive customer order," "Generate invoice," and "Update inventory."

Question 16

For each of the following statements, answer "a" if the statement is a true data-flow diagramming rule, and answer "b" if the rule is false.
-Data can move directly from one data store to another data store.

Accepted Answer

The answer of For each of the following statements, answer...

Question 17
