Computer ScienceChapter 12: Using Queries in Access
Action Queries
Update, append, delete, and make-table queries modify data and require preview, validation, and backup.
Learning objectives
- Define and explain action queries 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.

Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Action queries, Action, queries, and backup. precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples Update, append, delete, and make-table queries modify data and require preview, validation, and backup.
Working and Application
Working method: first identify the input or starting state for action queries; 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 action queries to a small school, home, or software problem and trace the result.
CONCEPT — What it means
Update, append, delete, and make-table queries modify data and require preview, validation, and backup.
TERMINOLOGY — Words to use
Terminology: use Action queries, Action, queries, and backup. 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 action queries; 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 action queries to a small school, home, or software problem and trace the result.
In simple words
Do not memorise the name 'Action queries' without explaining what information enters, what process occurs, and what result is produced.
