A data model contains___________________?

by
A data model contains___________________?

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.

Which diagram indicates the behaviour of the system as a consequence of external events ?

by
Which diagram indicates the behaviour of the system as a consequence of external events ?

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.

_______________________ defines the properties of a data object and take on one of the three different characteristics ?

_______________________ defines the properties of a data object and take on one of the three different characteristics ?

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.

The ______________ of a relationship is 0 if there is no explicit need for the relationship to occur or the relationship is optional ?

by
The ______________ of a relationship is 0 if there is no explicit need for the relationship to occur or the relationship is optional ?

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

The ________________ contains a state transition diagram that is a sequential specification of behavior?

by
The ________________ contains a state transition diagram that is a sequential specification of behavior?

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

The ___________________ enables the software engineer to develop models of the information domain and functional domain at the same time___________________?

by
The ___________________ enables the software engineer to develop models of the information domain and functional domain at the same time___________________?

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.

____________________ is a pidgin(simplified version of a language that develops as a means of communication between two or more groups that do not have a language in common)?

____________________ is a pidgin(simplified version of a language that develops as a means of communication between two or more groups that do not have a language in common)?

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 software component____________________?

by
A software component____________________?

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.
