Which diagram evolved from a desire to develop a procedural design representation that would not allow violation of the structured constructs ?
A. State transition diagram
B. Box diagram
C. ER diagram
D. None of the mentioned
A. State transition diagram
B. Box diagram
C. ER diagram
D. None of the mentioned
A. operations only
B. attributes only
C. both operations and attributes
D. none of the mentioned
Explanation: In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes, their attributes, operations, and the relationships among objects.
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. system context model
B. interaction model
C. environmental model
D. both system context and interaction
Explanation: The context model of a system may be represented using associations. Associations simply show that there are some relationships between the entities involved in the association.
A. functional domain
B. arbitrary transfer of control is impossible
C. recursion is easy to represent
D. providing a notation that translates actions and conditions
Explanation: This functionality is covered by UML diagrams.
A. Factory Method
B. Singleton
C. Observer
D. None of the mentioned
Explanation: In singleton pattern, the class itself is made responsible for keeg track of its instance.Thus it ensures that no more than one instance is created.
A. the design of interfaces between software components
B. the design of interfaces between the software and human producers and consumers of information
C. the design of the interface between two computers
D. all of the mentioned
