The ability to connect my SAP HANA database directly into our BI platform without any additional steps was great! I think they should allow for more flexibility in how we can use their product - it would be nice if there were other ways besides connecting straight from your DBMS or ODM that you could also integrate via API's (or similar).
As far as integrating this software goes, It is very powerful but not easy at first glance due to all its features/tools available within one package which are hard to navigate through when new users join the team so some training might help here too. We used them mainly because everything else seemed complicated compared to just using an ETL tool like Talend.
