Data Validation Feedback
What is it?
Error messages should explain the allowed value so correction is possible without weakening the rule.
In simple words
- Error messages should explain the allowed value so correction is possible without weakening the rule.
- Working method: first identify the input or starting state for data validation feedback; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
- Example: apply data validation feedback to a small school, home, or software problem and trace the result.
Important terms
Data validation feedback: Error messages should explain the allowed value so correction is possible without weakening the rule.
validation: Error messages should explain the allowed value so correction is possible without weakening the rule.
feedback: Error messages should explain the allowed value so correction is possible without weakening the rule.
What you should learn
- Define and explain data validation feedback in clear language.
- Use the important technical terms accurately.
- Describe the working process in the correct order.
- Apply the concept to a realistic computing example.
- Test or evaluate the result and state a limitation.
Examples
- Error messages should explain the allowed value so correction is possible without weakening the rule.
- Example: apply data validation feedback to a small school, home, or software problem and trace the result.
TERMINOLOGY AND CONCEPT
Terminology: use Data validation feedback, validation, feedback precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
WORKING AND APPLICATION
Working method: first identify the input or starting state for data validation feedback; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
