Hi,
I want to use the denormalization features in Designer/2000 Rel. 1.3.2.
Two tables, DEPT and EMP, are connected as usual. In DEPT, i
added a column SUM_SAL in the Data Diagrammer and defined in
the 'Validation' tab that it is denormalized from table EMP
via the foreign key EMP->DEPT.
I also defined that the column SAL should be summed.
I expected the Forms Generator to enhance my application with automatically generated values in the DCU SUM_SAL.
As you will already suspect, nothing happened. The field in my forms application behaves just like i defined only the column and said nothing about denormalization.
I understand that no triggers will be generated automatically.
Don't tell me to use a secondary usage to *display* the sum, i want it to be calculated and updated/inserted in the table.
Did i forget somthing? Any preference setting?
If the denormalization settings have no effect, why are they included in the Data Diagrammer?
Any help and comments are appreciated.
