1. A debugger component of a data processing system for a multidimensional database structure on a computer architecture that facilitates interactive development, analysis, understanding and debugging of Multi-Dimensional expression (MDX) query processing operations on a multidimensional database comprising: a primary central or distributed processing component, wherein said primary central component comprises a CPU; a data storage component, wherein the data storage component is a Multidimensional OnLine Analytical Processing Server (MOLAP), comprising one or more physical computer-readable media units operatively coupled to the primary central processing component, and which physically stores both the multidimensional database and a plurality of computer executable instructions; wherein the computer executable instructions operate on the primary central or distributed processing component to achieve the following system debugging system components: an input component, comprising a visual terminal, for multidimensional database queries to be entered by an end user; an analysis component, analyzing the multidimensional database queries entered by the end user which operates to break down a parent query into constituent parts and then associates each constituent part with contextual information pertaining to it, wherein said constituent parts comprise query segments and said contextual information comprises the value or content assigned in computing said query segment; a linking component which links each constituent part of the parent query and its associated information with the parent query as well as with the end-result of that parent query operating on the multidimensional database; and a display component which converts the information about each constituent part, its associated information, linked parent query and linked end-result into various intermediate display-formatted results for an end-user, then displays these display-formatted results to that end-user, wherein said intermediate display-formatted results do not comprise raw data.
