Computer ScienceChapter 12: Using Queries in Access
Query Testing
Check expected records, boundary dates, null values, duplicates, joins, calculations, and performance before relying on results.
Learning objectives
- Define and explain query testing 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.
Definition

Important terms
- Query testing
- Check expected records, boundary dates, null values, duplicates, joins, calculations, and performance before relying on results.
- Query
- Check expected records, boundary dates, null values, duplicates, joins, calculations, and performance before relying on results.

Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Query testing, Query, testing, Check expected records precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples Check expected records, boundary dates, null values, duplicates, joins, calculations, and performance before relying on results.
Working and Application
Working method: first identify the input or starting state for query testing; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
Examples Example: apply query testing to a small school, home, or software problem and trace the result.
CONCEPT — What it means
Check expected records, boundary dates, null values, duplicates, joins, calculations, and performance before relying on results.
TERMINOLOGY — Words to use
Terminology: use Query testing, Query, testing, Check expected records precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
WORKING — How it operates
Working method: first identify the input or starting state for query testing; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
EXAMPLE — Apply it
Example: apply query testing to a small school, home, or software problem and trace the result.
In simple words
Do not memorise the name 'Query testing' without explaining what information enters, what process occurs, and what result is produced.
