Interface Summary
MtmObjectVisitor A visitor object that can execute operations on some of the classes in the MtmObject class hierarchy.

 

Class Summary
MtmAggregationSpecification An MtmSolveSpecification that specifies how to solve an MtmUnsolvedCube, that is, which SQL function to apply when aggregating the data of the measures specified by the dimensions of the cube, the order in which to process the dimensions, and other aspects of the aggregation operations.
MtmAggregationStep An MtmObject that specifies the SQL function and other aspects of operations to perform when Oracle OLAP aggregates the values of the measures of an MtmUnsolvedCube for the dimension hierarchies of the MtmDimensionMap objects of this MtmAggregationStep.
MtmAttributeMap An MtmSourceMap for an MdmAttribute.
MtmAWColumnExpression An MtmColumnExpression that is based on a single column in a relational table or view for an analytic workspace.
MtmAWView An MtmTableOrView that is mapped to a dynamically generated inline view, for a dynamic analytic workspace, or to a static relational view, for a non-dynamic analytic workspace.

MtmCompoundTable An MtmTabularSource that represents a logical table that is based on the join of two component logical tables.
MtmCube An MtmObject that describes a cube, which has no equivalent object in the MDM metadata model but which is used for mapping MdmDimension and MdmMeasure objects to the SQL tables and expressions on which they are based.
MtmCubeDimensionality An MtmObject that stores information about the fact table and dimension tables (for one MdmDimension) that Oracle OLAP joins to construct the MdmMeasure objects that share the same MtmBaseCube.
MtmCustomExpression An MtmValueExpression based on a text string that evaluates to a valid SQL expression and was created by an application developer using the createCustomExpression method in the MdmCustomObjectFactory class.
MtmCustomObjectFactory An object that creates custom MtmObject objects.
MtmDataType Specifies the SQL data type characteristics for the mapping of an OLAP API data type to a SQL representation of that data type.
MtmDerivedAttributeMap An MtmAttributeMap for an MdmAttribute whose values are not explicitly stored but are derived from a column or columns in a dimension table.
MtmDimensionMap An MtmSourceMap for an MdmDimension.
MtmDimensionOrderSpecification An MtmObject that records the order in which elements of an MdmLevelHierarchy are arranged.
MtmExpression An MtmObject that represents a SQL expression whose form is appropriate for inclusion in the select list of a SELECT statement.
MtmFirstLastAggregationStep An MtmAggregationStep that specifies that Oracle OLAP use the measure value specified by the first or last child element of the current dimension node element when aggregating measure values specified by a dimension of the MtmAggregationStep.
MtmHierarchyMap An MtmSubDimensionMap for an MdmHierarchy.
MtmLevelHierarchyMap An MtmHierarchyMap for an MdmLevelHierarchy, which can be either solved or unsolved.
MtmLevelMap An MtmSubDimensionMap for an MdmLevel.
MtmLiteralExpression An MtmValueExpression based on a text string that evaluates to a valid SQL expression.
MtmMeasureMap An MtmSourceMap for an MdmMeasure.
MtmNoAggregationStep An MtmAggregationStep that specifies that Oracle OLAP does not aggregate the leaf-level measure data to the higher levels of the hierarchy of a dimension of the MtmAggregationStep.
MtmObject An object that describes the underlying SQL tables and expressions on which MDM metadata objects are based and records the mapping between the metadata and the underlying SQL structures.
MtmObjectFactory Creates MtmAggregationStep objects that you can use to specify the SQL function and other aspects of aggregating measure data from the leaf level to higher levels of a hierarchy of an MtmUnsolvedCube.
MtmPartitionedCube An MtmCube that has one or more MtmBaseCube objects, each of which holds information about one of the hierarchy combinations that are possible for the MtmPartitionedCube.
MtmPrimaryDimensionMap An MtmDimensionMap for an MdmPrimaryDimension.
MtmRDBMSColumnExpression An MtmValueExpression that is based on a single column in a relational table or view.
MtmRdbmsTableOrView An MtmTableOrView that represents a table or view that is based on relational data, and not on analytic workspace data.
MtmSelectStatement An MtmTabularSource that represents a logical table based on a SQL SELECT statement.
MtmSimpleAggregationStep An MtmAggregationStep that specifies a SQL function and a weighting factor to apply to the calculation of the measure values for the node levels of the hierarchies of the dimensions of this MtmAggregationStep.
MtmSolvedCube An MtmBaseCube for which both leaf-level and aggregate data is available directly from a relational table or view.
MtmSolvedCubeDimensionality An MtmCubeDimensionality object for one hierarchy in a solved MtmBaseCube.
MtmSolvedETCubeDimensionality An MtmSolvedCubeDimensionality object for one hierarchy in a solved MtmBaseCube whose fact table includes both detail (leaf) data and aggregate data for the associated measures.
MtmSolvedGroupingSetCubeDimensionality An MtmSolvedLevelBasedCubeDimensionality for one hierarchy in an MtmBaseCube whose fact table is structured in Grouping Set aggregation form.
MtmSolvedLevelBasedCubeDimensionality An MtmSolvedCubeDimensionality object for one hierarchy in a solved MtmBaseCube whose fact table includes only detail (leaf) data for the associated measures.
MtmSolvedLevelHierarchyMap An MtmLevelHierarchyMap for a solved MdmLevelHierarchy.
MtmSolvedRollupCubeDimensionality An MtmSolvedLevelBasedCubeDimensionality for one hierarchy in an MtmBaseCube whose fact table is structured in Rollup aggregation form.
MtmSolveSpecification An MtmObject that specifies how to solve an MtmUnsolvedCube, that is, which SQL function to apply when calculating the measure data for the node elements of the dimensions of the cube, the order in which to process the dimensions, and other aspects of the calculations.
MtmSourceMap An MtmObject that maps the relationship between an MdmSource and the underlying SQL tables and expressions on which the MdmSource is based.
MtmStoredAttributeMap An MtmAttributeMap for an MdmAttribute whose values are explicitly stored in a particular column or columns of a dimension table.
MtmSubDimensionMap An MtmDimensionMap for an MdmSubDimension.
MtmTableOrView An MtmTabularSource that represents a logical table that is based on an existing table or view in the data store.
MtmTabularSource An MtmObject that represents a logical table based on an existing table or view, a SELECT statement, or the join of two tables.
MtmUnsolvedCube An MtmBaseCube for which only leaf-level data is available directly from a relational table or view, and for which aggregate values are supplied by Oracle OLAP.
MtmUnsolvedCubeDimensionality An MtmCubeDimensionality object for one hierarchy in an unsolved MtmBaseCube.
MtmUnsolvedLevelHierarchyMap An MtmLevelHierarchyMap for an unsolved MdmLevelHierarchy.
MtmValueExpression An MtmExpression that represent a single expression, and so it does not have subexpressions.
MtmValueHierarchyMap An MtmHierarchyMap for an MdmValueHierarchy.
MtmValueLevelHierarchyMap An MtmValueHierarchyMap that provides access to the MtmSolvedLevelHierarchyMap for an MdmValueHierarchy.
MtmWeightedAverageAggregationStep An MtmAggregationStep that specifies a weighted average aggregation of the measure values for the node levels of the hierarchies of the dimensions of this MtmAggregationStep.

 

Exception Summary
MtmInvalidMetadataException Indicates that the requested operation on an MTM object cannot be performed, most likely because the specified parameters for the method are not valid.

 

Package oracle.olapi.metadata.mtm Description

Contains classes that map OLAP metadata objects to columns of relational tables and views and that specify aspects of the operations of those objects. Oracle OLAP creates multidimensional model (MDM) objects for the OLAP metadata objects.

You can use the classes in this package to get information about the MDM objects that Oracle OLAP creates for the OLAP metadata objects generated for a dynamic analytic workspace by the Oracle OLAP Analytic Workspace Java API. However, you cannot create custom metadata objects for an analytic workspace by using classes in this package. To create custom metadata objects for an analytic workspace, use the Oracle OLAP Analytic Workspace Java API.
