13.11 Measure Definition

The measure definition element stores the measure definition for a measure column. A measure column is usually in a fact table, can change for each record, and can be added up or aggregated in some way. The measure definition tag includes the following attributes: The measure definition tag does not include any child elements. Syntax MeasureDefn … isCommutative= Description MeasureDefn Example MeasureDefn name=Measure parentName=quot;Paintquot;.quot;Sales Factsquot;.quot;Dollarsquot; parentId=2006:26 id=2048:105 uid=106 isCommutative=false Description MeasureDefn

13.12 Aggregation Rule

The aggregation rule element corresponds to the aggregation rule object in the Business Model and Mapping layer. The aggregation rule tag includes the following attributes: The aggregation rule tag includes the following child elements: Table 13–20 Measure Definition Tag Attributes Attribute Name Description isCommutative If set to true, indicates that the aggregation rule lets the server switch the order if it can increase the performance. For example, the following aggregation function is commutative: A B x = B A x Table 13–21 Aggregation Rule Tag Attributes Attribute Name Description isDefault If set to true, indicates that this is the default rule for aggregate calculations. This option only applies when there is more than one aggregation rule. 13-18 Oracle Fusion Middleware Integrators Guide for Oracle Business Intelligence Enterprise Edition Syntax AggrRule … isDefault= BasedOnDimension Description Expr [CDATA[…]] Expr AggrRule Example AggrRule name=AggRule_2050:1121162340028 parentName=quot;Paintquot;.quot;Sales Factsquot;.quot;Unitsquot;. quot;Measurequot; parentId=2048:104 id=2050:112 uid=113 isDefault=true Description Expr [CDATA[ SUMPaint.Sales Facts.Units]] Expr AggrRule

13.13 Override Aggregation Rule

The override aggregation rule element corresponds to the override aggregation expression for a logical table source in the Business Model and Mapping Layer. When you select Count Distinct as the default aggregation rule, you can specify an override aggregation expression for specific logical table sources. This option is useful when you have more than one logical table source mapped to a logical column and you want to apply a different aggregation rule to each source. The override aggregation rule tag includes the following child elements: The override aggregation rule tag does not include any attributes. Table 13–22 Aggregation Rule Child Elements Element Name Description Expr Contains the expression on which this aggregation rule is based. BasedOnDimension If this aggregation rule is specific to a particular dimension, references the dimension for which this aggregation rule applies. The dimension is contained in a sub-element called RefDimension. Table 13–23 Override Aggregation Rule Child Elements Element Name Description RefLogicalTableSource References the logical table source to which this override aggregation rule applies. Expr Contains the expression on which this aggregation rule is based.

The logical display folder tag includes the following child elements: The logical display folder element does not include any attributes. Syntax LogicalDisplayFolder … Description Dimensions RefDimension … RefDimension … Dimensions Tables RefLogicalTable … RefLogicalTable… Tables LogicalDisplayFolder Table 13–24 Logical Display Folder Child Elements Element Name Description Dimensions References the dimensions that belong to this logical display folder. Each dimension is contained in a sub-element called RefDimension. Tables References the logical tables that belong to this logical display folder.
