PowerDesigner and the DSO metamodel

DSO uses hierarchically arranged groups of objects to define basic elements of Analysis Services data storage, as implemented by the Analysis server.


The following table lists the mappings between the objects contained within the DSO and PowerDesigner PDM metamodels:

DSO Object PowerDesigner PDM Object
clsDatabase Model

(Each model corresponds to a DSO Database.)
clsDataSource Data source
ClsDatabaseDimension Dimension

(As in the DSO model, PowerDesigner dimensions are shared among cubes.)
clsCube Cube

(Cubes managed by PowerDesigner are only local cubes.)
clsCube Fact

(A Fact corresponds to a DSO cube in order to store measures.)
clsCubeMeasure Measure
clsDatabaseDimension Dimension hierarchy

(Each dimension hierarchy is generated as a DSO Database Dimension. Attributes of a dimension hierarchy define levels of the corresponding DatabaseDimension.)
clsDatabaseLevel
clsCubeLevel
Dimension attribute

(Attributes of a dimension or dimension hierarchy define levels in a database dimension.)
clsCubeDimension Cube dimension association

(In DSO, when the name of a Cube Dimension corresponds to the name of a Database Dimension, the Cube Dimension is automatically associated with the Database Dimension to be shared between cubes.)
