Criteria
Criteria use comparison, range, wildcard, null, date, and logical operators to define which records appear.
Learning objectives
- Define and explain criteria 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
Criteria use comparison, range, wildcard, null, date, and logical operators to define which records appear.
Important terms
- Criteria
- Criteria use comparison, range, wildcard, null, date, and logical operators to define which records appear.
- Criteria use comparison
- Criteria use comparison, range, wildcard, null, date, and logical operators to define which records appear.
Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Criteria, Criteria use comparison precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples Criteria use comparison, range, wildcard, null, date, and logical operators to define which records appear.
Working and Application
Working method: first identify the input or starting state for criteria; 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 criteria to a small school, home, or software problem and trace the result.
CONCEPT — What it means
Criteria use comparison, range, wildcard, null, date, and logical operators to define which records appear.
TERMINOLOGY — Words to use
Terminology: use Criteria, Criteria use comparison 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 criteria; 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 criteria to a small school, home, or software problem and trace the result.
In simple words
Do not memorise the name 'Criteria' without explaining what information enters, what process occurs, and what result is produced.
