Structure Diagrams Flashcards

All 6 cards in this deck

What is a structure diagram?: A visual chart showing how the parts of a system are broken down, interconnected and organised.
In a structure diagram, what does each box represent?: A separate part (subsection) of the system.
How is a structure diagram organised?: Hierarchically — the whole problem is the top box, with subsections on the levels below joined by lines to show their links.
Give one advantage of using a structure diagram.: It is a planning tool used before coding, so errors or missing parts are spotted early.
Give one drawback of using a structure diagram.: It becomes confusing if made overly detailed, and must be updated whenever the system changes.
True or false? A structure diagram shows the order in which the steps of an algorithm are carried out.: False. It shows how the problem breaks into subsections and how they link; a flowchart shows the order of steps.
