The change of data type appears in the list of domains.
Undefined data type
If you do not want to select a data type immediately, you can choose
the <Undefined> data type. When you generate the database, this data
type is replaced by the default data type for your target object
language.
Selecting a data type from a list of standard data types
You can select a data type from a list of standard data types. This is the same
list that is available in the Conceptual Data Model. PowerDesigner
automatically maps the standard data type to an OOM data type.
The length and precision are properties that do not apply to all data types.
Furthermore, depending on data type, length may indicate a maximum or a
fixed number of characters.
The classes below indicates the data types for which you can specify:
♦ Fixed length
♦ Maximum length
♦ Decimal precision
