Design and Implementation

A. data object
B. attributes
C. relationships
D. all of the mentioned

Explanation: The data model consists of three interrelated pieces of information: the data object,
the attributes that describe the data object, and the relationships that connect data objects to one another.

A. describing the customer complaints
B. establishing a basis for the creation of a software design
C. defining a set of requirements that can be validated once the software is built
D. none of the mentioned

Explanation: All the options are covered in analysis model.

A. data flow diagram
B. state transition diagram
C. control specification diagram
D. workflow diagram

Explanation: The state transition diagram represents the various modes of behavior (called states) of the system and the manner in which transitions are made from state to state.

A. data object
B. attributes
C. relationships
D. data object and attributes

Explanation: They can be used to name an instance of the data object, describe the instance, or make reference to another instance in another table.

A. modality
B. cardinality
C. entity
D. structured analysis

Explanation: The modality is 1 if an occurrence of the relationship is mandatory, else 0 for optional relationship

A. data flow diagram
B. state transition diagram
C. control specification
D. workflow diagram

Explanation: The control specification(CSPEC. describes the behavior of the system, but it gives us no information about the inner working of the processes that are activated as a result of this behavior

A. data flow diagram
B. state transition diagram
C. control specification
D. workflow diagram

A. data flow diagram
B. state transition diagram
C. control specification
D. activity diagram

Explanation: As the DFD is refined into greater levels of detail, the analyst performs an implicit functional decomposition of the system, thereby accomplishing the fourth operational analysis principle for function.

A. program design language
B. structured English
C. pseudocode
D. all of the mentioned

Explanation: The difference between PDL and a real programming language lies in the use of narrative text embedded directly within PDL statements.

A. Implements some functionality
B. Has explicit dependencies through provides and required interfaces
C. Communicates through its interfaces only
D. All of the mentioned

Explanation: All the options identify with features of a software component.
