Hello all,
Could you please help to provide information / clarify me per background and questions below?
Background:
My Head office has planned to use SAP HANA with our current data warehouse system. They plan to use SAP HANA, BI Platform 4.1 and SAP Explorer.
The first phase is not using Cloud. May be next phase.
So far, we have not received any update from them. 
Only SAP HANA training that will be provide to us early of next year.
However, my team hear need to prepare on our side. Our role here is the system analyst and developer.
Our assumption is SAP HANA server will live at head office. We will just need to connect to the HANA server for DW reports development.
Questions:
1. What do we need to prepare or install as the client side.
We have been researching for SAP HANA Client and Studio. It seems both 2 software are required to install. What else we need to do?
If we install both of them and connect to SAP HANA server in head office, will this be enough for development?
2. If Cloud computing has been implemented, anything we need to prepare on our side.
3. What about if we need to use just BI Platform 4.1 (i.e., WEBI or explorer)? Do we need to install SAP HANA Client and Studio?
4. What about JAVA version that allow us to develop WEBI or Explorer on IE 8?
Thank you very much in advance. 
Awora.
