The Plungers Ordering system

This is a very simple system. I have seen requests like this from users for many years. Of course, they have their own types of plungers.

The usual scenario, which will also be described here, includes:

• the business analyst asks the users to describe the requirement
• the users tell their view of the system in their own words
• the business analyst translates the user requirement into a set of specifications to tell the coders
• the coders come up with a design
• the process of system construction starts ending with a system that meets the users' requirements

Of course this is very simplified and there are many detours to trip us up at each step.

Next I will describe in more detail 2 ways to construct the Plungers Ordering System.
