Chapter 12 Generating Other Models from an OOM
PDM generation translates OOM objects into physical objects.
| OOM object | PDM object after generation |
|---|---|
| Domain | Domain |
| Class | Table (only if the Persistent and Generate check boxes are selected in the class property sheet) |
| Interface | Not translated |
| Attribute | Column (only if the Persistent check box is selected in the attribute property sheet) |
| Identifier | Identifier |
| Operation with <<storedProcedure>> stereotype | If the parent class is generated as a table, the operation is generated as a stored procedure attached to the table.
The operation body is generated as a body in the procedure definition. The generated procedure has the same name as the operation, however, if a name conflict occurs, a number is added to the name of the procedure |
| Operation with <<storedFunction>> stereotype | If the parent class is generated as a table, the operation is generated as a stored function attached to the table.
The operation body is generated as a body in the function definition. The generated function has the same name as the operation, however, if a name conflict occurs, a number is added to the name of the function |
| Association | Reference or table |
| Association class | A table and two associations between the end points of the association class |
| Dependency | Not translated |
| Realization | Not translated |
| Generalization | Reference |
For a class to become a table you need to select the Persistent check box and define a type of generation in the Generation list in the Detail tab of the class property sheet.
The cardinality of a class becomes the number of records of a table.
If the association has a many-to-many multiplicity: both roles of the association have the * sign selected in their multiplicity lists, the association is translated into a table in the generated PDM. If it has any other multiplicity, the association becomes a reference.
A role name becomes a migrated foreign key after PDM generation.
