L4-Transformation Accessment
Posted: Sat Jul 05, 2003 8:32 am
Hi,
Can anyone give me an example of the data filter on how to analyse L4?
In L0, we can use base check type and produce an exception table that contain the column and the count of that column.
In L1, we can use exist to access the completeness and in ref list and in range to access the validity.
In L2, we can use unique to check the duplicates and in ref col to check referencial integrity.
In L3, we can use type, format...... to check the business rules.
How about L4?
Thanks,
Cai Bing
