Daanse Tutorial - Cube Calculated Member Color ​

This tutorial discusses Calculated Members and Measures with different colors.

Database Schema ​

The Database Schema contains the Fact table with three columns: KEY and VALUE and VALUE_NUMERIC. 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.

Level ​

This Example uses one simple Level 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_thelevel" name="theLevel">
  <column href="_column_fact_key"/>
</rolaplev:Level>

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

Hierarchy without hasAll Level ​

The Hierarchy is defined with the hasAll property set to true and the one level.

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_thehierarchy" name="theHierarchy" primaryKey="_column_fact_key" source="_tablesource_fact" levels="_level_thelevel"/>
  <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_thelevel" name="theLevel" column="_column_fact_key"/>
  <rolapsrc:TableSource xmi:id="_tablesource_fact" table="_table_fact"/>
</xmi:XMI>

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

Dimension ​

The dimension is defined with the one hierarchy. The hierarchy is used in the cube and in the calculated member.

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_thedimension" name="theDimension" hierarchies="_explicithierarchy_thehierarchy"/>
  <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_thehierarchy" name="theHierarchy" primaryKey="_column_fact_key" source="_tablesource_fact" levels="_level_thelevel"/>
  <rolaplev:Level xmi:id="_level_thelevel" name="theLevel" column="_column_fact_key"/>
  <rolapsrc:TableSource xmi:id="_tablesource_fact" table="_table_fact"/>
</xmi:XMI>

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

Cube and DimensionConnector and Measure ​

The cube is defined by the DimensionConnector and the MeasureGroup and most importantly the calculated members.
