If I have used the DQS cleansing and matching some datas using a Knowledge Base at the first step. And then I just do it again, that is , I cleanse and match
the data which have handled at the previous step using the same KB .
Then , what DQS works ? Just repeat the cleansing and matching processes, or it will ignore and skip these two processes beacuse the KB is the same one and the reslut would be unchanged.
I would like to know whether DQS is
intelligent and efficient when it using the KB to cleanse and match without doing
repetitive tasks ? For example,timestamp orother waysto markwhetherthedatabaseis
I really need to make clear that but i have not try it with DQS. Please help to answer.

DQS will run process again and you will see the same results as at the
previous step, because your KB was not changed(improved). If you are going
to collect data for your KB (expend KB), then you should do the following:
1. Create KB
2. Run Cleanse and Match for you External Data
3. Import result into EXCEL file
4. IMPORT DATA FROM EXCEL TO YOUR KB. This will increase data( Knowledge about your data)
5. repeate steps 2-4 until expected results.

Well, you see the point is that KB and Cleanse,Match process should be considered as one separate mechanism which helps to normalize data.
External data is a source which should normalized there should not be any kind of timestamps.
