What is the main focus of Reverse Engineering (RE) ? 

The correct answer is Data base structure.

Key Points

• Reverse Engineering (RE) involves the process of analyzing a system to identify the system's components and their interrelationships, creating representations of the system in another form or at a higher level of abstraction.
• The main focus of RE is to understand the database structure which is crucial in understanding how data is stored, accessed, and managed within the system.
• This understanding can help in various activities such as system maintenance, migration, or integration with other systems.
• RE can also be used to recover lost information, detect and correct errors, or enhance the performance of the system.

Additional Information

• Reverse Engineering is also used in software development to understand the code of legacy systems for updating or replicating functionalities in new systems.
• It can help in security analysis to find vulnerabilities and ensure that the system is protected against potential threats.
• RE can be applied to hardware and software systems, including analyzing executable binaries to understand their behavior.
• Ethical considerations should be taken into account while performing RE, as it may involve intellectual property and privacy concerns.
