According to an article in PC World: On this article,  SAP's new High Performance Analytic Appliance " will be compatible with any other BI application that supports common query languages like SQL and MDX".  SAP's current BW data warehouse product supports the MDX query language and it is good to see SAP continuing to support open data access standards like SQL and MDX.  Apparently, there will be more information coming from Vishal Sikka (SAP's CTO) at the SAP TechEd conference tomorrow: http://www.sapteched.com/usa/activities/keynotes.htm.  Stay tuned.
