It is also known as a transaction-oriented processing system. Its basic feature is that the customer's raw data can be immediately transmitted to the Computing Center for processing and the processing results can be given in a very short t

Introduction to Mondrian MDX
MDX (multidimen1_expression) is the language used to construct and query OLAP databases, just as SQL is used to build and operate relational databases.
MDX was the first developed by Microsoft and is part of the 1997 system ole db for OLAP (ODBO). Mosha Pasumansky is one of the MDX Language designers. MDX is soon implemented by oth
