Cube with examples of roles with MemberGrant Cube1 - access to 'A'
Cube with access MemberGrant
This tutorial discusses role with MemberGrant
role1 role: with member grants [Dimension1].[A] -all, [Dimension1].[B] -none, [Dimension1].[C] -none; (Cube1 - access to 'A' only)
Rollup policy: (Full. Partial. Hidden.) Full. The total for that member includes all children. This is the default policy if you don't specify the rollupPolicy attribute. Partial. The total for that member includes only accessible children. Hidden. If any of the children are inaccessible, the total is hidden.
Database Schema
The Database Schema contains the Fact table with two columns: KEY and VALUE. The KEY column is used as the discriminator in the the Level and Hierarchy definitions.
<roma:DatabaseSchema id="databaseSchema">
<tables xsi:type="roma:PhysicalTable" id="_Fact" name="Fact">
<columns xsi:type="roma:PhysicalColumn" id="_Fact_KEY" name="KEY"/>
<columns xsi:type="roma:PhysicalColumn" id="_Fact_VALUE" name="VALUE" type="Integer"/>
</tables>
</roma:DatabaseSchema>Note: This is only a symbolic example. For the exact definition, see the Definition section.
Query
The Query is a simple TableQuery that selects all columns from the Fact table to use in in the hierarchy and in the cube for the measures.
<roma:TableQuery id="_FactQuery" table="_Fact"/>Note: This is only a symbolic example. For the exact definition, see the Definition section.
Level1
This Example uses one simple Level1 bases on the KEY column.
<roma:Level id="_Level1" name="Level1" column="_Fact_KEY"/>Note: This is only a symbolic example. For the exact definition, see the Definition section.
Hierarchy1 without hasAll Level1
The Hierarchy1 is defined with the hasAll property set to false and the one level2.
<roma:ExplicitHierarchy id="_Hierarchy1" name="Hierarchy1" hasAll="false" primaryKey="_Fact_KEY" query="_FactQuery" levels="_Level1"/>Note: This is only a symbolic example. For the exact definition, see the Definition section.
Dimension1
The dimension1 is defined with the one hierarchy1.
<roma:StandardDimension id="_Dimension1" name="Dimension1" hierarchies="roma:ExplicitHierarchy _Hierarchy1"/>Note: This is only a symbolic example. For the exact definition, see the Definition section.
Cube1 with access all
The cube1 is defines by the DimensionConnector1 and the DimensionConnector2 and the MeasureGroup with measure with aggregation sum.
<roma:PhysicalCube id="_Cube1" name="Cube1" query="_FactQuery">
<dimensionConnectors foreignKey="roma:PhysicalColumn _Fact_KEY" dimension="roma:StandardDimension _Dimension1" overrideDimensionName="Dimension1"/>
<dimensionConnectors foreignKey="roma:PhysicalColumn _Fact_KEY" dimension="roma:StandardDimension _Dimension1" overrideDimensionName="Dimension2"/>
<measureGroups>
<measures xsi:type="roma:SumMeasure" id="_Measure1" name="Measure1" column="_Fact_VALUE"/>
</measureGroups>
</roma:PhysicalCube>Note: This is only a symbolic example. For the exact definition, see the Definition section.
