Question on CKM and Data Quality

Question

As I understand, CKM only supports the check based on db constraints. If I want to have more complicated business logic built to the checking, does Data Quality sound like a good choice. Or other suggestions?
In my case, I will need to check the data in the source table based on the table data from different sources (both target and source tables). This should be doable through data quality, correct? I am new to ODI. When I first installed the ODI, I didn't choose to install data quality module. I suppose I can install DQ separately and link it back to ODI? Do they share the same master repository?
Sorry for the naive questions, you help is greatly appreciated.

Hi,
My idea is just like:
for instance a FK validation:
create function F$_validate_FK (value1 number) return number
as
v_return number;
begin
select my_fk into v_return from any_table where column_fk = value1 ;
return v_return ;
exception
When NO_DATA_FOUND then
return -1;
end;
And at constraint you will have:
-1 = (select F$_validate(table1.column_to_be_validated) from dual)
Any record that have -1 as return will be not valide for the flow.
The F$ function can be created in a ODI procedure before the interface and dropped at end if you think to be necessary.
Make any sense?
(Maybe there are several syntax error in this example, I just write it and did not compilate, just to show the idea)
