OpenCellset: IAdoMdCellset;
The OpenCellset method returns analytical data obtained after executing a random MDX query to cube.
Executing the example requires that the repository contains an ADOMD catalog with the ADOMDTest identifier. The catalog contains the ADOMD cube with the Cube_1 identifier.

On executing the example a multidimensional query is executed for the specified ADOMD cube. The information about the axes, on which the data is formed, is obtained from execution result. Information about all axes is displayed in the development environment console: number and names of dimensions, that are used to form axis coordinates, and number of attributes for each dimension, that describe each coordinate.
