Discuss
Answer: (c).A two-step process of deriving a logical design in the form of data flow diagrams and transforming it into a program structure Explanation:Structured Analysis is a two-step process that involves deriving a logical design in the form of data flow diagrams and transforming it into a program structure.
Q594.
What is the purpose of context diagrams in data flow design?

a.

To depict the interaction of a system with the environment

b.

To expand the central process node of a data flow diagram

c.

To describe the algorithm of a process in minispecs

d.

To serve as a lower level diagram in a hierarchy of diagrams

Discuss
Answer: (a).To depict the interaction of a system with the environment Explanation:Context diagrams are data flow diagrams that depict the interaction of a system with the environment (the collection of external entities).
Q595.
What is the purpose of minispecs in data flow design?

a.

To serve as a lower level diagram in a hierarchy of diagrams

b.

To depict the interaction of a system with the environment

c.

To communicate the algorithm of a process to relevant parties

d.

To expand the central process node of a data flow diagram

Discuss
Answer: (c).To communicate the algorithm of a process to relevant parties Explanation:Minispecs serve to communicate the algorithm of a process to relevant parties and may use notations such as structured natural language, pseudocode, or decision tables.
Q596.
What is the purpose of the data dictionary in a Data Flow Diagram (DFD)?

a.

To describe the algorithm of a process

b.

To model the static aspects of the data

c.

To record the contents of the data flows

d.

To provide a hierarchical set of structure charts

Discuss
Answer: (c).To record the contents of the data flows Explanation:The contents of the data flows in a DFD are recorded in a data dictionary, which is a precise description of the structure of the data.
Q597.
What is the result of Structured Analysis?

a.

A set of data flow diagrams

b.

A hierarchical set of structure charts

c.

A logical model of the system

d.

A collection of modules

Discuss
Answer: (c).A logical model of the system Explanation:The result of Structured Analysis is a logical model of the system, which consists of a set of DFDs, augmented by descriptions of its constituents in the form of minispecs, formats of data stores, and so on.
Q598.
What is the result of the Structured Design step?

a.

A set of data flow diagrams

b.

A logical model of the system

c.

A hierarchical set of structure charts

d.

A collection of modules

Discuss
Answer: (c).A hierarchical set of structure charts Explanation:The result of the Structured Design step is expressed in a hierarchical set of structure charts, where the data flow diagrams are transformed into a collection of modules (subprograms) that call one another and pass data.
Q599.
What is the major heuristic in the Structured Design step?

a.

The choice of the top-level structure chart

b.

The choice of the central transformation

c.

The choice of the dummy root element

d.

The choice of the Input-Process-Output scheme

Discuss
Answer: (a).The choice of the top-level structure chart Explanation:The major heuristic in the Structured Design step involves the choice of the top-level structure chart, which is often based on the central transformation.
Q600.
How is the central transformation decided in a data-processing system?

a.

By choosing the dummy root element

b.

By tracing the input through the DFD until it can no longer be considered input

c.

By tracing the output through the DFD until it can no longer be considered output

d.

Both b and c

Discuss
Answer: (d).Both b and c Explanation:The central transformation in a data-processing system is decided by tracing the input through the DFD until it can no longer be considered input and tracing the output through the DFD until it can no longer be considered output. The bubble in between acts as the central transformation.
