OBJECT and SQLJ OBJECT abstract data
types allow you to specify attributes and procedures. In this example, we will create an
Address object with Street, City, and ZipCode attributes.
- Open the property sheet of the abstract data type and select
either OBJECT or SQLJ_OBJECT from the type
list.
The following additional tabs are displayed.
- Attributes - lets you specify object (or
SQLJ object) attributes with appropriate data types.
- Procedures - lets you specify object (or
SQLJ object) procedures with appropriate parameters.
- Click the Attributes tab and use the
Add a Row tool to create appropriate attributes,
specifying a Name, Code,
Data Type, and, if appropriate, select the
Mandatory (M) check box:
- Click the Procedures tab and use the
Add a Row tool to create appropriate procedures,
specifying a Name and Code, and,
if appropriate, selecting the Final (F),
Static (S) and/or Abstract (A)
check boxes.
An object abstract data type with a supertype can inherit non-final
procedures. Use the Inherit Procedure tool to select a
non-final procedure from a parent abstract data type.
- Click OK to return to your model.
