The left pane contains the source data models in a hierarchical tree view. A root node represents a .dbm file in your data design project. You can add source schemas incrementally with the drag and drop function, or the Add Schema menu option.
The right pane contains the target data models or schemas. Targets are limited to one database or one XML schema.
The center pane contains the mapping lines and mapping hubs.
Viewing the mapped elements in a mapping editor that contains a large source or target tree can sometimes be difficult. The mapping editor provides filter options that you can select to hide the mapped or unmapped tree objects. The filter options are available from the drop down menus in the source and target views, and in the Mappings view. When you select the filter options from the Mappings view, the filter options apply to both the source and target trees. Select Hide Unmapped Objects to hide the tables and XSD complex elements that contain no mapped children. Select Hide Mapped Objects to hide the tables and XSD complex elements with children that are all mapped. Select Show All to show all of the tree objects. Select Hide Selected or Hide Unselected from the context menu options on the source and target panes to hide individual tree objects.
The outline view captures the summary information of the mapping model that is currently active. The outline view shows the files as a hierarchical tree. You cannot modify this view. The outline view and the mapping editor are connected. As you update your mappings, the outline is also updated. The mapping editor and the outline view are always synchronized.
You can use the Find function to search for text strings in the outline view. This function is particularly useful when you have many mapped relationships, and the graphical representation contains numerous lines.
The name of the mapping model is the parent node of the hierarchy. The child nodes are the sources, targets, and mapping groups. Column transformations are shown in the mapping entry in the outline. Filters, joins and sorts are shown in the mapping group. You can expand and collapse the outline view by mapping nodes.
The properties view is separate from the mapping editor, but provides details of the columns and table metadata. The properties view shows details about the selected object in the active editor. The following example displays the properties view when the mapping view that is shown in Figure 1 is selected.
