Daanse Tutorial - Access Catalog Grant ​

This tutorial discusses roles with CatalogGrant.

  • roleAll role : use CatalogGrant access all; (access cube1)
  • roleNone role : use CatalogGrant access none; (no access cube1)
  • roleAllDimWithCubeGrand role : use CatalogGrant access all_dimensions; CubeGrant cube1 access all; cube2 access none (access cube1)
  • roleAllDimWithoutCubeGrand role: use CatalogGrant access all_dimensions without cube grant (As result is 'no access'. For access need CubeGrant with custom or all)

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 Level and Hierarchy definitions.

xml
<relational:Schema xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"  xmlns:relational="http://www.omg.org/spec/CWM/1.1/resource/relational" xmi:id="_schema">
  <ownedElement xsi:type="relational:Table" xmi:id="_table_fact" name="Fact">
    <feature xsi:type="relational:Column" xmi:id="_column_fact_key" name="KEY"/>
    <feature xsi:type="relational:Column" xmi:id="_column_fact_value" name="VALUE"/>
  </ownedElement>
</relational:Schema>

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

Query ​

The Query is a simple TableSource that selects all columns from the Fact table to use in the hierarchy and in the cube for the measures.

xml
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"  xmlns:relational="http://www.omg.org/spec/CWM/1.1/resource/relational" xmlns:rolapsrc="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/database/source">
  <rolapsrc:TableSource xmi:id="_tablesource_fact" table="_table_fact"/>
  <relational:Table xmi:id="_table_fact" name="Fact">
    <feature xsi:type="relational:Column" xmi:id="_column_fact_key" name="KEY"/>
    <feature xsi:type="relational:Column" xmi:id="_column_fact_value" name="VALUE"/>
  </relational:Table>
</xmi:XMI>

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

Level1 ​

This Example uses one simple Level1 based on the KEY column.

xml
<rolaplev:Level xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:rolaplev="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/olap/dimension/hierarchy/level" xmi:id="_level_level1" name="Level1">
  <column href="_column_fact_key"/>
</rolaplev:Level>

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.

xml
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"  xmlns:relational="http://www.omg.org/spec/CWM/1.1/resource/relational" xmlns:rolaphier="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/olap/dimension/hierarchy" xmlns:rolaplev="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/olap/dimension/hierarchy/level" xmlns:rolapsrc="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/database/source">
  <rolaphier:ExplicitHierarchy xmi:id="_explicithierarchy_hierarchy1" name="Hierarchy1" hasAll="false" primaryKey="_column_fact_key" source="_tablesource_fact" levels="_level_level1"/>
  <rolapsrc:TableSource xmi:id="_tablesource_fact" table="_table_fact"/>
  <relational:Table xmi:id="_table_fact" name="Fact">
    <feature xsi:type="relational:Column" xmi:id="_column_fact_key" name="KEY"/>
    <feature xsi:type="relational:Column" xmi:id="_column_fact_value" name="VALUE"/>
  </relational:Table>
  <rolaplev:Level xmi:id="_level_level1" name="Level1" column="_column_fact_key"/>
</xmi:XMI>

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

Dimension1 ​

The dimension1 is defined with the one hierarchy1.

xml
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"  xmlns:relational="http://www.omg.org/spec/CWM/1.1/resource/relational" xmlns:rolapdim="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/olap/dimension" xmlns:rolaphier="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/olap/dimension/hierarchy" xmlns:rolaplev="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/olap/dimension/hierarchy/level" xmlns:rolapsrc="https://www.daanse.org/spec/org.eclipse.daanse.rolap.mapping/database/source">
  <rolapdim:StandardDimension xmi:id="_standarddimension_dimension1" name="Dimension1" hierarchies="_explicithierarchy_hierarchy1"/>
  <rolapsrc:TableSource xmi:id="_tablesource_fact" table="_table_fact"/>
  <relational:Table xmi:id="_table_fact" name="Fact">
    <feature xsi:type="relational:Column" xmi:id="_column_fact_key" name="KEY"/>
    <feature xsi:type="relational:Column" xmi:id="_column_fact_value" name="VALUE"/>
  </relational:Table>
  <rolaphier:ExplicitHierarchy xmi:id="_explicithierarchy_hierarchy1" name="Hierarchy1" hasAll="false" primaryKey="_column_fact_key" source="_tablesource_fact" levels="_level_level1"/>
  <rolaplev:Level xmi:id="_level_level1" name="Level1" column="_column_fact_key"/>
</xmi:XMI>

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

Cube1 with access all ​

The cube1 is defined by the DimensionConnector1 and the DimensionConnector2 and the MeasureGroup with measure with aggregation sum.
