What methodology is deployed to guarantee the ongoing evolution of legacy systems ?
Show answer Hide answer
Answer: D. Reverse Engineering and Reengineering
Explanation
Legacy system evolution requires both reverse engineering and re-engineering methods. Reverse engineering analyzes old code, while re-engineering modernizes the architecture. Both processes work together to keep aging software operational and secure. Legacy systems accumulate technical debt and become harder to maintain over time. Organizations must modernize core software without losing critical business logic. Comprehensive evolution strategies combine analytical and transformative techniques.
Banks modernize decades old mainframe systems using reverse and re-engineering. IT consultants assess legacy codebases to plan safe system migration paths. Combining both approaches ensures long term viability for critical business applications. Forward engineering alone cannot comprehend undocumented legacy code structures. Reverse engineering alone analyzes code without transforming it into a modern system. Re-engineering alone lacks the initial code analysis provided by reverse engineering.
