Cube with examples of roles with TableGrant
roleAll role: use TableGrant access all; (access all database all tables) roleNone role: use TableGrant access none; (no access to database tables) roleCustom role: use TableGrant access custom; (access to database table Fact)
Cube with role access column
This tutorial discusses roles with ColumnGrant.
roleAll role: use TableGrant access all; (access all database all tables all columns) roleNone role: use TableGrant access none; (no access to database columns)
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.
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">
<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.
roleAll
The roleAll use TableGrant access all; (access all tables columns)
<roma:AccessRole id="_roleAll" name="roleAll">
<accessCatalogGrants catalogAccess="all">
<cubeGrants cubeAccess="all" cube="roma:PhysicalCube _Cube1"/>
<databaseSchemaGrants databaseSchemaAccess="custom" databaseSchema="databaseSchema">
<tableGrants tableAccess="custom" table="_Fact">
<columnGrants columnAccess="all" column="_Fact_VALUE"/>
<columnGrants columnAccess="all" column="_Fact_KEY"/>
</tableGrants>
</databaseSchemaGrants>
</accessCatalogGrants>
</roma:AccessRole>
Note: This is only a symbolic example. For the exact definition, see the Definition section.
roleNone
The roleNone use ColumnGrant access none; (no access to all tables columns)
<roma:AccessRole id="_roleNone" name="roleNone">
<accessCatalogGrants catalogAccess="all">
<cubeGrants cubeAccess="all" cube="roma:PhysicalCube _Cube1"/>
<databaseSchemaGrants databaseSchemaAccess="custom" databaseSchema="databaseSchema">
<tableGrants tableAccess="custom" table="_Fact">
<columnGrants column="_Fact_VALUE"/>
</tableGrants>
</databaseSchemaGrants>
</accessCatalogGrants>
</roma:AccessRole>
Note: This is only a symbolic example. For the exact definition, see the Definition section.
