Chapter 12 Generating Other Models from an OOM
PowerDesigner supports both object languages and physical data types. Data types you select in the OOM are not always supported by the current DBMS. In this case, the data type is translated to a data type supported by the DBMS when you generate the PDM. Physical data types are converted into conceptual data types (the internal types in PowerDesigner).
You can check the mappings between object language and physical data types in the object language, from Language→Edit Current Object Language. The physical data types are converted into conceptual data types.
In the object language, you have to expand the Settings category and click the DataTypes category to display the following values:
| Value | Description |
|---|---|
| BasicDataTypes | List of data types of the current object language and their equivalent conceptual data types. BasicDataTypes are the most common data types used |
| AdditionalDataTypes | List of additional data types. Can be used to add or change data types of your own |
| ConceptualDataTypes | List of conceptual data types with their equivalent data type in the current object language. They are the internal data types of PowerDesigner, and cannot be modified |
| DefaultDataType | Default data types used in an OOM |
For more information on data types, see section Data types category, in chapter Object Languages Reference Guide in the Advanced User Documentation.
