Computer ScienceChapter 11: Using Forms in Access
Subforms
A subform displays related many-side records inside a one-side main form using linked fields.
Learning objectives
- Define and explain subforms 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
A subform displays related many-side records inside a one-side main form using linked fields.
Important terms
- Subforms
- A subform displays related many-side records inside a one-side main form using linked fields.
Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Subforms precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples A subform displays related many-side records inside a one-side main form using linked fields.
Working and Application
Working method: first identify the input or starting state for subforms; 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 subforms to a small school, home, or software problem and trace the result.
CONCEPT — What it means
A subform displays related many-side records inside a one-side main form using linked fields.
TERMINOLOGY — Words to use
Terminology: use Subforms 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 subforms; 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 subforms to a small school, home, or software problem and trace the result.
In simple words
Do not memorise the name 'Subforms' without explaining what information enters, what process occurs, and what result is produced.
