public class AWCubeOrganization

extends CubeOrganization

A CubeOrganization for an analytic workspace. An AWCubeOrganization contains options that affect the data loading, aggregation method, storage, and querying of an MdmCube. To get an existing AWCubeOrganization or to create a new one, use the findOrCreateAWCubeOrganization method of the MdmCube.

One option controls the creation of materialized views (MVs) for the measures and dimensions that are associated with the cube. MVs can be automatically refreshed, which can be useful in maintaining the analytic workspace. An MV can be used by the database query rewrite system, which can result in significantly enhanced performance of SQL queries. However, a cube that uses MVs has limitations because the cube must meet certain requirements, which are listed in the description of the setMVOption method. Another limitation is that a cube that has MVs cannot have a derived measure.

Oracle Database has systems for refreshing the data associated with an MV and for transparently rewriting a query so that it uses an MV. With the setMVOption method, you can specify whether or not to create an MV and the type of MV to create. The options that specify the creation of an MV determine the structure of the MV and the conditions required for the creation of the MV. If you specify the creation of a MV, then you can use an MVCreationOptions object to set values that affect the actual creation of the MV and that can replace the default values.

A Java application can demand a refresh by calling the DataProvider.executeBuild method for the cube. Building the cube refreshes the MV. You can specify properties that affect the building of the cube by passing a BuildProperties object to the executeBuild method.

For more information on cube partitioning, sparsity types, storage types, and the use of MVs, see Oracle OLAP User's Guide.

With the setMVOptions method, you can specify the type of materialized view to create or you can specify not to create one for the cube. If you specify creating a type of materialized view, you can use an MVCreationOptions object to specify values that Oracle OLAP uses when it actually creates the MV.

Returns:

An MVCreationOptions that contains options that affect the creation of a materialized view.
