Physical Elements 14-23 The physical hierarchy tag includes the following child elements: Syntax PhysicalHierarchy … extName= type= dimType= rowCount= isTimeDim= dimUniqueName= isMemberAliasUnique= Columns RefCubeColumn … Columns MemberKey RefCubeColumn … MemberKey ParentKey RefCubeColumn … ParentKey Levels RefPhysicalLevel … Levels PhysicalHierarchy isMemberAliasUnique Indicates whether member names including aliases are unique in a given hierarchy so that the Oracle BI Server can take advantage of specific MDX syntax to optimize performance. This option corresponds to the Use unqualified member name for better performance option in the Physical Hierarchy dialog in the Administration Tool. Table 14–22 Physical Hierarchy Child Elements Element Name Description Columns For parent-child value hierarchies. References the set of cube columns that belong to this physical hierarchy. Each cube column is contained in a sub-element called RefCubeColumn. MemberKey For parent-child value hierarchies. References the cube column that is the member key for this hierarchy. The member key column is contained in a sub-element called RefCubeColumn. ParentKey For parent-child value hierarchies. References the cube column that is the parent key for this hierarchy. The parent key column is contained in a sub-element called RefCubeColumn. Levels For level-based hierarchies. References the set of physical levels that belong to this physical hierarchy. Each level is contained in a sub-element called RefPhysical Level. Table 14–21 Cont.

14.14 Physical Level

The physical level element corresponds to the hierarchical levels for a physical cube table object in the Physical layer. The physical level tag includes the following attributes: The physical level tag includes the following child elements: Syntax PhysicalLevel … levelNumber= extName= rowCount= LevelKey RefCubeColumn … LevelKey PhysicalLevel Example PhysicalLevel name=Year parentName=quot;FoodMartquot;...quot;Salesquot;.quot;Timequot; parentId=3041:4200 id=3045:5791 uid=2147496776 levelNum=0 extName=Year DescriptionDescription LevelKey RefCubeColumn id=3043:4261 qualifiedName=quot;FoodMartquot;... Table 14–23 Physical Level Tag Attributes Attribute Name Description levelNum Identifies the order of this physical level in the hierarchy. extName Fully qualified name for the level. rowCount The latest number of rows retrieved for this physical level. Table 14–24 Physical Level Child Elements Element Name Description LevelKey References the key column for this physical level. The key column is contained in a sub-element called RefCubeColumn.

14.15 Cube Column

The cube column element corresponds to the cube column of a physical cube object in the Physical layer. The cube column tag includes the following attributes: The cube column tag includes the following child elements: Table 14–25 Cube Column Tag Attributes Attribute Name Description extName The external name for the cube column. This attribute is required if the same name such as STATE is used in multiple hierarchies. aggrType The type of aggregation on the column, if any. dataType The data type of the cube column, such as VARCHAR. nullable If set to true, indicates that null values are allowed for the column. This allows null values to be returned to the user, which is expected with certain functions and with outer joins. precision The precision of the data type of the cube column. scale The scale of the data type of the column. rowCount The latest number of rows retrieved for this cube column. lastUpdated The time at which row counts were last updated for this cube column. dimPropType For Essbase dimensional columns only. Indicates the property type of the cube column. Valid values are: ■ uda: User Defined Attribute UDA type. ■ memnor: Memnor type, used for outline sorts in the logical layer. Imported at the lowest level of each dimension. Called Outline Sort in the Administration Tool. ■ attribute: Attribute type, for attribute dimensions. ■ other: The type is different than those listed, or unknown. ■ none: The column does not have a property type. Note that this type is mapped to Member Alias in the Administration Tool. ■ ancestorRef: References the ancestor of a dimension. ■ memberKey: The column is a member key. ■ levelNumber: The column is the lowest member of the hierarchy. Called Leaf in the Administration Tool. ■ genNumber: The column is the root member of the hierarchy. Called Root in the Administration Tool. ■ parentRef: References the parent of a dimension. 14-26 Oracle Fusion Middleware Integrators Guide for Oracle Business Intelligence Enterprise Edition Syntax CubeColumn … extName= aggrType= dataType= nullable= precision= rowCount= lastUpdated= scale= AttributeHierarchy RefPhysicalHierarchy … AttributeHierarchy PhysicalLevel RefPhysicalLevel … PhysicalLevel CubeColumn Example CubeColumn name=Year parentName=quot;FoodMartquot;...quot;Salesquot; parentId=3039:4260 id=3043:4261 uid=2147487198 extName=Year dataType=VARCHAR scale=0 precision=8 nullable=false DescriptionDescription CubeColumn
