Q. What is RE-ENGINEERING?

RE-ENGINEERING:- It is re-organizing as well as modifying existing system to make them more maintainable. It involves

• Source code translation.
• Reverse engineering.
• Program structure development.
• Program modularization.
• Data re-engineering.

Restructuring or else re-writing part or every of the legacy system without hanging its functionality. Legacy system is a system that is hard to maintain. Thus it involves:-

1) Re-documenting the system.

2) Organizing as well as re-structuring the system.

3) Modifying as well as upgrading structure as well as value of the system data.

4) Input to a re-engineering process is a legacy system as well as output is a structure modularized version of the same program. So re-engineering involves adding effort to make them easier to maintain. The system possibly restructured or else re-documented.
