ITPEC FE Morning October 2023 Question 50

Reverse Engineering — extracting design documents (E-R diagrams) from an existing active database.

The question describes generating a design document from definition information in an active database — going from implementation back to documentation.

• •Forward engineering: design document → implementation (E-R diagram → create database)
• •Reverse engineering: implementation → design document (active database → E-R diagram)

Why not others:
- (a) Concurrent engineering — developing multiple project phases in parallel
- (b) Forward engineering — generating implementation from design documents (opposite direction)
- (d) Social engineering — manipulating people to gain information; a security concept

Key rule: If the source is a working system and the output is documentation → reverse engineering.
