what is main difference between change capture and change apply stages..

Answer / abdullah

read answer 2 first because i`m appending this answer to it so u can understand more.

*change capture views you the records that were change only, without telling you the rest of of the original records
ex: if one records was changed among 5 records then it will view it alone.
-(it will take two input, the before data set and the after data set)

*change apply should take the original data set and the change capture data set and then apply the change to the original copy as an output. as a result you have now all the records including the new and changed ones.
