Aspects of Software Development (AQA A-Level Computer Science): Flashcards

Analysis, design, implementation, testing, evaluation

Foundation stage; rushing it creates problems later

Breaking system down into smaller units/modules

Shows how data moves around a system

Specifies what data is used and how it's stored

Data within acceptable range that system should handle

Data on extremes of acceptable range (min/max values)

Clearly incorrect data program should catch as error

Testing input produces correct output without examining how

Ensuring different tested modules work together
