⟩ Explain in type2 dimension/flag current mapping there are three data flows i.e1. data flow for new rows2 .data flow for changed row3. data flow for updated changed rowwhats the difference between last two data flow?
When we are working with FLAG we can use only 2 filter transformations
also but at the initial stage it will be better to go with 3 filters. Where we
are using the FIRST Filter to insert the records for first
time, In second Filter we are inserting the records but these records are with
updated information and in third filter we are updating the records with
surrogate key. This third filter records will be updated with our changed
FLAG value 'ZERO'. Because we are identifying the current records with FLAG
values 'ONE'.
