♦ An output card ( ) contains the complete definition of an output for a map.
The output definition includes information such as target identification,
destination specifics, and the behavior that should occur during processing.
Each input of data and each output of data requires content definition settings.
The content of each card is specified as a type in a type tree.
Each card represents one data object that is identified by selecting a type from a
type tree. A card may represent an object in a row, a row in a record, the entire
record, or the entire file.
Each card specifies a type tree and a type as part of the card definition. This type,
and the type tree that contains it, is the link between the Type Designer and the
Map Designer that defines the structure and properties of the data in the card.
♦ The input card represents input data. Input data validation occurs in the Type
Designer when the type tree is analyzed.
♦ The output card represents output data and contains the map rules that
transform that data. Therefore, only the output card has a rule column.
