Unit 1 Exam Revision Flashcards
What is the problem solving methodology?
The problem solving methodology is followed to ensure that the most appropriate solution is found and implemented when an information problem exists.
What are the stages of the problem solving methodology?
Analysis, Design, Development and Evaluation.
What is done in each stage of the problem solving methodology?
Analysis involves establishing the root cause of the problem by identifying solution requirements, establishing solution constraints and defining the scope of the solution.
Design involves planning several alternatives and choosing the most appropriate one by creating the solution design and specifying the evaluation criteria.
Development involves creating the solution by manipulating or coding the solution, checking the accuracy of data input by validation, ensuring a solution works through testing and documentation that allows users to interact or use the solution.
Evaluation involves assessing a solution to ensure it has been successful by working out an evaluation strategy and reporting on the success of the solution.
What is data?
Data can be defined as unprocessed, unorganised and distinct facts or ideas.
What is information?
Information can be defined as processed, organised and value-added data.
