Creating graphical data maps
You can create graphical data maps either in the Broker Development view of the Toolkit, or from a Mapping node.
When you create a new graphical data map, you provide a name for the map and a .map extension is added. The .map file is saved either in the specified broker schema in the project in which you created the map with the map creation wizard, or in the same project and broker schema as the message flow when you double-click on a newly added Mapping node in that message flow.
When you have created the map, the navigator displays the saved map resource under a Maps category, organized by the mapping namespace.
If you have imported your message maps (.msgmap files) from WebSphere® Message Broker Version 7, you can convert them to graphical data maps; see Converting a message map from a .msgmap file to a .map file.
You can use the graphical data map to construct a graphical data map by using a wide variety of mapping transform functions. The transforms operate either from an input element to an output element on the canvas, or by directly setting the value of an output element.
You can use the functions either by using drag-and-drop, or from a context menu action on the input or output element. The Graphical Data Mapping editor inserts the most appropriate mapping function on the newly created transform connection. For transforms that require multiple input connections, you can drag additional connections onto the transform, and you can then select either a primary or supplementary connection mode. The Graphical Data Mapping editor adjusts the type of transform based on the new connections. When the connection has been created, you can optionally change the type of transform function or start setting properties.
Some types of transforms involving complex input and outputs are edited by entering into a nested view. The editor provides arrow buttons and breadcrumb navigation for nested transforms.
For information about the transforms that you can use in a graphical data map, see Transform types in the Graphical Data Mapping editor.
