Computer ScienceChapter 9: Introduction to Data Access
Importing and Linking
Import copies external data into the database, while linking keeps a connection to an external source.
Learning objectives
- Define and explain importing and linking 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
Import copies external data into the database, while linking keeps a connection to an external source.
Important terms
- Importing and linking
- Import copies external data into the database, while linking keeps a connection to an external source.
- Importing
- Import copies external data into the database, while linking keeps a connection to an external source.
- linking
- Import copies external data into the database, while linking keeps a connection to an external source.
Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Importing and linking, Importing, linking precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples Import copies external data into the database, while linking keeps a connection to an external source.
Working and Application
Working method: first identify the input or starting state for importing and linking; 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 importing and linking to a small school, home, or software problem and trace the result.
CONCEPT — What it means
Import copies external data into the database, while linking keeps a connection to an external source.
TERMINOLOGY — Words to use
Terminology: use Importing and linking, Importing, linking 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 importing and linking; 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 importing and linking to a small school, home, or software problem and trace the result.
In simple words
Do not memorise the name 'Importing and linking' without explaining what information enters, what process occurs, and what result is produced.
