If a schema is defined externally, what does not need to be edited when the source data changes?

• A. The writer settings
• B. The data source
• C. The external schema table
• D. The workspace

Answer: (D)

External schemas separate the data structure from the workflow, so changes in the source data can be accommodated by updating the external schema rather than modifying the workflow itself. The workspace relies on that external definition to interpret attributes and types, meaning the workspace can stay as is while you adjust the external schema to reflect new fields or changes. Writer settings or the data source might still need tweaks if those aspects change, but the workspace itself does not need editing when the schema is defined externally.
