Thank you for the suggestion.
At the stage of "Startup Focus program's Development Accelerator", the following web page is directed to download SAP HANA Studio: Get your own SAP HANA, developer edition on Amazon Web Services (http://scn.sap.com/docs/DOC-28294, Part 3 - Download and install SAP HANA Studio and SAP HANA Client), where I get SAP HANA Studio.
Any suggestion how to update my HANA Studio?
