Reverse engineering is the process of deriving the system design and specification from its____________________?
A. GUI
B. Database
C. Source code
D. All of the mentioned
Software Engineering types
Much of the information necessary to create a behavioral model can be obtained by observing the external manifestation of the existing ________________________?
Much of the information necessary to create a behavioral model can be obtained by observing the external manifestation of the existing ________________________?
A. candidate keys
B. interface
C. database structure
D. none of the mentioned
Explanation: The GUI or the interface provides the base for the behavioral model.
Which of the following is not an objective of reverse engineering ?
Which of the following is not an objective of reverse engineering ?
A. to reduce maintenance effort
B. to cope with complexity
C. to avoid side effects
D. to assist migration to a CASE environment
Explanation: Reverse engineering helps us to detect side effects rather than avoiding them.
Which of the following steps may not be used to define the existing data model as a precursor to re-engineering a new database model ?
Which of the following steps may not be used to define the existing data model as a precursor to re-engineering a new database model ?
A. Build an initial object model
B. Determine candidate keys
C. Refine the tentative classes
D. Discover user interfaces
Explanation: Once information defined in the preceding steps is known, a series of transformations can be applied to map the old database structure into a new database structure.
What have become de rigueur for computer-based products and systems of every type ?
What have become de rigueur for computer-based products and systems of every type ?
A. GUIs
B. Candidate keys
C. Object model
D. All of the mentioned
Explanation: Therefore, the redevelopment of user interfaces has become one of the most common types of re-engineering activity. But before a user interface can be rebuilt, reverse engineering should occur.
In reverse engineering process, what refers to the sophistication of the design information that can be extracted from the source code ?
In reverse engineering process, what refers to the sophistication of the design information that can be extracted from the source code ?
A. interactivity
B. completeness
C. abstraction level
D. direction level
Forward engineering is also known as_________________?
Forward engineering is also known as_________________?
A. extract abstractions
B. renovation
C. reclamation
D. both renovation and reclamation
Explanation: Forward engineering, also called renovation or reclamation , not only recovers design information from existing software, but uses this information to alter or reconstitute the existing system in an effort to improve its overall quality
The core of reverse engineering is an activity called________________?
The core of reverse engineering is an activity called________________?
A. restructure code
B. directionality
C. extract abstractions
D. interactivity
Explanation: The engineer must evaluate the old program and extract a meaningful specification of the processing that is performed, the user interface that is applied, and the program data structures or database that is used.
Source code translation is a part of which re-engineering technique ?
Source code translation is a part of which re-engineering technique ?
A. Data re-engineering
B. Refactoring
C. Restructuring
D. None of the mentioned
Explanation: Restructuring involves automatic conversion from unstructured to structured code.
Which of these benefits can be achieved when software is restructured ?
Which of these benefits can be achieved when software is restructured ?
A. Higher quality programs
B. Reduced maintenance effort
C. Software easier to test
D. All of the mentioned
Explanation: The answer is self explanatory.
