ServiceNow CAD free question 7 / 10 · Domain 5: Working with External Data
Which record defines what data an import set should import?
- Import set table
- Field map
- Transform map
- Data source
Show the answer and explanation
Answer: D
Why this is correct
The Create a data source page states its purpose directly: you create a data source record to define what data an import set should import. Data sources come in types such as File and JDBC, each with its own procedure. The data source is the start of the chain: records imported from it land in the import set table, the staging area, and a transform map then copies them to the target table.
Why the other options are wrong
"Transform map" … A transform map determines the relationships between fields in an import set table and fields in an existing table. It does not decide what is imported.
"Import set table" … The import set table is the staging area for records imported from a data source. It holds the rows rather than defining them.
"Field map" … A field map is one field relationship inside a transform map, including whether that field is used to coalesce.
The order of the parts
Data source, then import set table, then transform map, then target table. Whatever the type of data source, the staging and transform steps after it work the same way.
