While it was not an open standard, but rather a Microsoft-owned specification, it was adopted by the wide range of OLAP vendors. This included both vendors on the server side such as Applix, icCube, MicroStrategy, NCR, Pentaho, Oracle Corporation, SAS, SAP, Teradata, Symphony Teleca, and vendors on the client side such as Panorama Software, Pentaho, PowerOLAP, XLCubed, Proclarity, AppSource, Jaspersoft, Cognos, Business Objects, Brio Technology, Crystal Reports, Microsoft Excel, Tagetik, and Microsoft Reporting Services.
With the invention of XML for Analysis, which standardized MDX as a query language, even more companies - such as Hyperion Solutions - began supporting MDX.
The XML for Analysis specification referred back to the OLE DB for OLAP specification for details on the MDX Query Language. In Analysis Services 2005, Microsoft has added some MDX Query Language extensions like subselects. Products like Microsoft Excel 2007 have started to use these new MDX Query Language extensions. Some refer to this newer variant of MDX as MDX 2005.
