re: Hana and Exalytics: SAP's Hype Versus Oracle's FUD
HANA does support the MDX query language. In fact, Simba worked very closely with SAP to build MDX capabilities directly into HANA. Uwe Fischer from SAP and I presented at the SAP BI conference in March this year how you can easily connect from Microsoft Excel to SAP HANA using OLE DB for OLAP (ODBO) and the MDX query language.
From the Oracle side, the Oracle database does not support the MDX query language natively like HANA does. For Oracle database OLAP Option, you need to separately license the Simba MDX Provider for Oracle OLAP to get this capability.
Oracle Times Ten also does not support the MDX query language.
Oracle Essbase does support the MDX query language. However, Essbase only supports XMLA and does not support ODBO. Therefore, many applications like Microsoft Excel will not be able to connect to Essbase using the MDX query language.
SAP BW - MDX (yes), ODBO (yes), XMLA (yes)
SAP HANA - MDX (yes), ODBO (yes), XMLA (yes)
Oracle database OLAP Option - MDX (add-on from Simba), ODBO (add-on from Simba), XMLA (coming soon from Simba)
Oracle Times Ten - MDX (no), ODBO (no), XMLA (no)
Oracle Essbase - MDX (yes), ODBO (no), XMLA (yes)
