Chapter 12 Creating Mappings
Each sub-object in the source object can be associated with a sub-object of the target object in order to specify where and how attribute values are stored in the database or model. The sub-object of the source object is displayed in the Selection dialog box in order to let you create a mapping with these inherited sub-objects. You can use the following tools to define sub-object mappings:
| Tool | Description |
|---|---|
|
Add Mapping - Allows you to select the sub-objects in the target object that will be mapped to sub-objects in the source object. Once you have selected the sub-objects, you can use the list in the Source column to select the corresponding sub-objects in the source object. |
|
Create from Sources - Allows you to copy sub-objects from the object in the source model to the target object. The name, code , description, annotation, and comment are copied and the data types are converted in order to match the current model. |
|
Generate Mapping - Allows you to automatically generate a mapping between sub-objects with same name or code in the source and target models. |
The Ellipsis button in the Source column opens the SQL Editor or the Object Expression Editor dialog box to let you customize the source expression for the sub-objects.
