Flashcards in Design Notations Deck (13):
1

What are structure diagrams?

A graphical representation of the top down design process where blocks in the program correspond to modules in the program

2

Data flow diagrams are used to...

Represent how data is passed between modules

3

What is meant by Pseudocode?

Pseudocode is an informal description of the logic of each module which is then used to write source code

4

What is a wireframe?

A graphical notation which not only helps the developer plan the application but also allows the client to influence the design and navigation at an early stage

5

What are wireframes used in?

Web Development as well as program design

6

Top down design

The design approach of breaking a large and complex problem down into smaller, more manageable problems

7

What happens with modules in a structure chart?

They become modules in the finished program

8

Give three examples of graphical design notation

Wireframe
Structure Diagram
Data flow diagram

9

Which design notation requires data structures to be decided on before it can be created?

Data flow diagram

10

Which design notation would you use to design a user interface?

Wireframe

11

Which design notation is the simplest to create source code from?

Pseudocode

12

What is stepwise refinement?

The creation of Pseudocode from the structure diagram and data flow diagram

13

Why are Graphical Design Notations used in the design process?

To help the developers break the problem down into manageable sub problems
