Sorting Records
Ascending and descending sorts change display order, not stored meaning, and multiple fields create primary and secondary order.
Learning objectives
- Define and explain sorting records 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

Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Sorting records, Sorting, records, not stored meaning precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples Ascending and descending sorts change display order, not stored meaning, and multiple fields create primary and secondary order.
Working and Application
Working method: first identify the input or starting state for sorting records; 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 sorting records to a small school, home, or software problem and trace the result.
CONCEPT — What it means
Ascending and descending sorts change display order, not stored meaning, and multiple fields create primary and secondary order.
TERMINOLOGY — Words to use
Terminology: use Sorting records, Sorting, records, not stored meaning 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 sorting records; 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 sorting records to a small school, home, or software problem and trace the result.
In simple words
Do not memorise the name 'Sorting records' without explaining what information enters, what process occurs, and what result is produced.
