Question

The __________ enables the software engineer to develop models of the information domain and functional domain at the same time

(a) data flow diagram

(b) state transition diagram

(c) control specification

(d) activity diagram

This question was posed to me in unit test.

My doubt stems from Analysis Modelling topic in section Design and Implementation of Software Engineering

Answer 1

Right option is (a) data flow diagram

The best I can explain: As the DFD is refined into greater levels of detail, the analyst performs an implicit functional decomposition of the system, thereby accomplishing the fourth operational analysis principle for function.
