XML for Analysis is an open, web-based standard for client-server communications between OLAP systems. Since its debut in mid-2001 XML/A has been widely considered to perform poorly in comparison with proprietary, binary protocols as the overhead involved in creating XML documents at one end and then parsing them at the other end was thought to be high. Additionally, the XML output from an XML/A server is much larger in terms of actual bytes as the XML document must contain many tags which are required to describe the actual data they contain. This means that the time to transfer the data across the network is greater.
