Maps define how data is transformed by the Integration
Appliance during run time. Maps can reorganize data, convert data,
suppress or add data, and performing calculations or other complex
conversions.
Maps can transform data from one or more sources to one
or more destinations. For example, during run time a map can transform
XML data valid against one XML Schema to XML data valid against another
XML Schema. The XML Schemas and Flat File Schemas you use to define
the source and destination nodes of a map must exist in the current
project before you start creating a map. For more information about
uploading an XML Schema or DTD to a project, see Uploading Files
into a Project. For more information about creating a Flat
File Schema, see Creating a flat file schema.
The
following types of maps can be created in Studio:
- Inline maps - Inline or embedded maps are not visible in
the Project tab. These maps are created automatically
inline when you configure activities that contain Map Input and Map
Output tasks, or when you configure a Map Variables activity.
The source and destination types of an inline map are determined from
the variables you select by clicking Add in
the From Orchestrations and To Orchestrations panes of the Mapping
Editor. Inline maps transform data from one or more source
variables to one or more destination variables. The source and destination
variables can be of any data type.
- Standalone maps - A standalone map is visible in the Transformations folder
of the Project tab and represents a set of
one or more mappings between source and destination nodes. You can
create standalone maps by right-clicking the Transformations folder
in the Project tab or from the toolbar menu option. For
more information, see Creating a Standalone Map.
The source and destination types of an inline map are determined from
the schema types you select by clicking Add in
the From Orchestrations and To Orchestrations panes of the Mapping
Editor.
You can also test a map against sample data, for more information
see
Testing maps.
