Techniques for representing the design of solution
Design solution : Solved information problems that meet certain information need
Representing a solution
Techniques for representing solutions :
- Flowcharts : Provide a convenient diagrammatic technique. Symbols that are used to construct a flowchart :
- Pseudocode : Pseudocode uses what is known as 'Structured English' to represent the steps in a solution.
The two most command word structures that are used in Pseudocode are if/then/else and repeat/until
Eg: START
IF pay greater than $600
THEN set tax to 30% of $600
ELSE set tax to 10% of $600
END
- Structure Charts : Show the broad overviiew of the solution to problems that involve various levels or processing options.
- Layout design sheets : To represent all aspects of the solution (flowcharts, pseudocode, and structure charts)
- Data flow diagrams and context diagrams : Show the flow of information from the sources of the data and the destination of the resulting information derived for the data
