Cube with examples of roles with DimensionGrant Cube1 - Dimension1 all access Cube1 - Dimension2 no access

Cube with role with DimensionGtant

This tutorial discusses roles with DimensionGrant.

role1 role: use DimensionGrant access to Dimension1 and not access to Dimension2 of cube1

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 level1.

<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 _Dimension2" 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.

Role1

The role1 use CatalogGrant access all_dimensions; CubeGrant cube1 access all; cube2 access none (access cube1)

<roma:AccessRole  id="role1" name="role1">
  <accessCatalogGrants catalogAccess="custom">
    <cubeGrants cubeAccess="custom" cube="roma:PhysicalCube _Cube1">
      <dimensionGrants dimensionAccess="all" dimension="roma:StandardDimension _Dimension1"/>
      <dimensionGrants dimension="roma:StandardDimension _Dimension2"/>
    </cubeGrants>
    <databaseSchemaGrants databaseSchemaAccess="all" databaseSchema="databaseSchema"/>
  </accessCatalogGrants>
</roma:AccessRole>

Note: This is only a symbolic example. For the exact definition, see the Definition section.
