Design Notations Flashcards
What are structure diagrams?
A graphical representation of the top down design process where blocks in the program correspond to modules in the program
Data flow diagrams are used to…
Represent how data is passed between modules
What is meant by Pseudocode?
Pseudocode is an informal description of the logic of each module which is then used to write source code
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
What are wireframes used in?
Web Development as well as program design
Top down design
The design approach of breaking a large and complex problem down into smaller, more manageable problems
What happens with modules in a structure chart?
They become modules in the finished program
Give three examples of graphical design notation
Wireframe
Structure Diagram
Data flow diagram
Which design notation requires data structures to be decided on before it can be created?
Data flow diagram
Which design notation would you use to design a user interface?
Wireframe
Which design notation is the simplest to create source code from?
Pseudocode
What is stepwise refinement?
The creation of Pseudocode from the structure diagram and data flow diagram
Why are Graphical Design Notations used in the design process?
To help the developers break the problem down into manageable sub problems
