ITPEC FE Morning April 2022 Question 51
ITPEC FE Morning April 2022 — Question 51 of 80
Reverse Engineering in Software Reengineering — identify the sub-process focused on functional analysis and information extraction.
Software reengineering has four sub-processes:
- •Program modularization — breaking a program into smaller, independent modules
- •Program structure improvement — refactoring code to improve readability and maintainability
- •Reverse engineering — analyzing existing code to extract functional specs, design info, and architecture
- •Source code translation — converting code from one programming language to another
Reverse engineering focuses on functional analysis and information extraction — understanding what a system does and how, by examining the finished product.
Why not others:
- (a) Program modularization — restructures code into modules, does not analyze functionality
- (b) Program structure improvement — improves code quality, not about extracting information
- (d) Source code translation — converts between languages, no analysis involved
Key rule: "Functional analysis + information extraction" = reverse engineering.
