oracle.olapi.metadata.deployment.CubeOrganization
public abstract class CubeOrganization
A metadata object that represents the organization of an MdmCube
as a relational OLAP (Rolap) object or as an analytic workspace (AW) object. An application creates a CubeOrganization
with the createAWOrganization
or createRolapOrganization
method of the MdmCube
.
Oracle OLAP uses materialized views to store aggregated data for the measures of a cube. A sparse dimension is one for which the measures of the cube have data for less than 80% of the members of the dimension. Oracle OLAP stores the data for sparse dimensions in a structure that is more efficient for querying the data. You can specify a sparse dimension by calling the addSparseDimension
method and passing it the MdmDimensionality
object associated with the dimension.
Method Summary | |

getCube() Gets the MdmCube that is associated with the CubeOrganization . |
java.util.List |
getSparseDimensions() Gets the MdmDimensionality objects for the sparse dimensions of the cube. |
void |
removeSparseDimension(MdmDimensionality dim) Removes an MdmDimensionality from the sparse dimensions of the cube. |
