Dear Raphael,
The Software is SAP BW.
But people who are into SAP BW are moving to HANA as its in more demand now. Combination of BW and HANA also adds value.
In HANA there is Modeling for Data Analysis which I believe would be suitable for you.
Or you can go for SAP Fiori and SAP UI5 which are also in demand now.
You can check the videos in Youtube and you will get an overview idea regarding these and then you can jump on the one which you like the most.
All the Best.
Regards
Shaik
