Glen,
In the context of directly connecting to SAP HANA, there are two tools in the SAP BusinessObjects portfolio for interacting with OLAP sources. The first is Analysis for OLAP. Analysis for OLAP is a web based tool that is started via the BI Launch Pad. Its core connectivity engine runs on the BOBJ Platform under the Adaptive Process umbrella which is called the Multidimensional Analysis Service. It uses an embedded JDBC driver to connect directly to a SAP HANA appliance. The second tool is Analysis for Microsoft Office. It runs as a plugin for Excel. In order to connect this desktop based client tool to SAP HANA, you must first install the SAP HANA client and configure an ODBC DNS within Windows desktop. It too connects directly to SAP HANA using the ODBC driver.
I hope this helps.
