Difference between New ETL and Old ETL

Question

Hi All,
In old ETL process we first have a InfoSource (Can be connected from DataSources from Different Source Systems). We have 1 set of Transfer Rules. Again if there are different definitions to be loaded into different data target we define them in Update Rules.
What incase of new ETL is the purpose of maintaining 2 transformations (Replacing Update Rules and Tranfer Rules). Can't we directly define different transformations on DataSource itself. Where the requirement comes that we define two transformations with InfoSource in between.

Hi Ravi,
What incase of new ETL is the purpose of maintaining 2 transformations (Replacing Update Rules and Tranfer Rules). Can't we directly define different transformations on DataSource itself. Where the requirement comes that we define two transformations with InfoSource in between.
.here is the requirement
suppose thr are some modification required to be done in an infoobject value ..suppose the value '1' is to be replaced by 'Y'  in an infoobject for all data targets...then such a modification will be put in the transformation from datasource to infosource and after that individual transformations are applied from infosource to different data targets,these transformation are data target specific rules..like update rules..in this case u only had to write the rule for 1-->Y once in first transformation ...
So in short .. transfer rules as well as update rules are now called transformations.....
yes u can directly define transformations on datasource itself as well ..infosource is not mandatory
