Answers




171.
Answer :   (a)
Reason :   Analysis phase is to determine what the system must do, is the main issue in documentation.
172.
Answer :   (b)
Reason :   :              the symbol represents generalization.
173.
Answer :   (c)
Reason :    Structured design is a data-flow-based methodology. The approach begins with a system specification that identifies inputs and outputs and describes the functional aspects of the system.
174.
Answer :   (a)
Reason :   The UML diagram provides static structure of a system is Class diagram. 
175.
Answer :   (d)
Reason :    System testing means it is the execution of a program to check logic changes made in it and with the intention of finding errors- making the program fail. Effective testing does not guarantee reliability. Reliability is a design consideration.
176.
Answer :   (a)
Reason :   In module coupling there must be at least one connection between a module and a calling module.
177.
Answer :   (c)
Reason :   The feasibility report of an existing system highlights problem areas.
178.
Answer :   (a)
Reason :   Collaboration diagram depicts a pattern of messages coming into and going from an object.
179.
Answer :   (b)
Reason :    Implementation is used to mean the process of converting a new or revised system design into an operational one as conversion is one aspect of implementation. The other aspects are post-implementation review and software maintenance.
180.
Answer :   (b)
Reason :    The rules and semantics of the UML can be expressed in a form known as Object Constraint Language (OCL).
