I know that Data Service is more about connecting to the social networks to extract, transform and load the data beside to this, it performs Text Analysis ...etc ...but after this those data will be saved on HANA In-Memory ...but why we need to work with SAP HANA Modeler, the data are already processed by Data Service?? .... i need this explanation somehow because I'm working on Sentiment Analysis using SAP HANA Sentiment Intelligence RDS.
thanks alot
