Given three $(3)$ main modules of a software system, namely the User Interface, the Database, and the

Reporting Module, draw a diagram to illustrate how these three $(3)$ modules could be organized in a project

plan that is based on:

$1)$ The Waterfall Model $($see Fig. $2-4,$ p$.41)$

$2)$ The Overlap Model $($see Fig. $2-5,$ p$\mathrm{.}42),$ using $3$ iterations

$3)$ The Spiral model $($see Fig. $2-6,$ p$.43),$ using $3$ iterations

Be sure that you indicate explicitly where each of the three modules listed above fits into the project plan

$($using their names indicated above$),$ and how each module fits into the number of iterations, where

applicable. This includes the order in which each module is developed. You can draw these diagrams

manually, but please make them neat and clear! Then describe$/$discuss at least one advantage and

disadvantage of each of these SDLC models.
