Axis Element (XMLA)
Contains a set of tuples used to represent a single axis in a multidimensional dataset contained by an Axes element that uses the MDDataSet data type, returned by the Execute method.

Замечания
The content of the Axis element varies depending on the value of the AxisFormat XMLA property used by the Execute method.
TupleFormat
When a client application sets the AxisFormat property to TupleFormat, an axis is represented as a set of tuples. Each Axis element contains a Tuples element that represents the set of tuples on that axis. Each tuple is represented by using a Tuple element that contains Member elements from every hierarchy on the axis.
ClusterFormat
When a client application sets the AxisFormat property to ClusterFormat, the members on each axis are divided into clusters in which each cluster represents a cross-product between ordered sets of members from each hierarchy. Each Axis element consists of one or more CrossProduct elements. Every CrossProduct element contains a Members element for each hierarchy on the axis.
CustomFormat
When a client application sets the AxisFormat property to CustomFormat, the value is treated the same as the TupleFormat value by an Analysis Services instance.
Examples
Description
The following example illustrates the structure of the Axis elements when a client specifies TupleFormat or CustomFormat for the AxisFormat XMLA property, given the following members for the axis:
Time hierarchy |
1999 |
1999 |
2000 |
Category hierarchy |
Actual |
Budget |
Budget |
