Hello Gagandeep,
SAP C4C can also be integrated to SAP On Prem systems via SAP PI or SAP HCI using the pre-packaged content.
It can also be integrated with Social sites like facebook, twitter as well as SAP JAM.
It can not only be accessed using the browsers but also with Mobile Apps for Android and iOS.
Accessing data from SAP Cloud, makes the data available everywhere via internet to provide you the real time analysis.
Lot of standard Reports are already provided by SAP for Data Analytic.
Hope this gives you more information.
Regards,
Chandan
