The Transaction object specifies the parameters that PowerBuilder uses to connect to a database.
You can customize your own version of the Transaction object by defining a class user object inherited from the built-in Transaction object.
For more information about creating a custom Transaction object, see the section called “Working with User Objects” in Users Guide.
For more information about using the Transaction object in an application, see the section called “Using Transaction Objects” in Application Techniques.
