Logical to Physical objects Mapping

Question

Recently installed OLAPTRAIN's SALESTRACK AW, and noticed that there are many __AW_GENERATED.. object names.
It is very difficult trying to trace back what these objects refer to, and quite challenging if we are using OLAP DML commands to create custom reports.
This is the result of the 30 character limit AWM has when concatenating cube and measure names and concatenating dimension and attributes names.
As an example for the Measure "Cross Over Linear Regression" (Logical Name: SALES_CUBE.CROSS_OVER_LINEAR_REGRESSION)
"CROSS_OVER_LINEAR_REGRES" is COLUMN_NAME value in SALES_CUBE view and in ALL_CUBE_VIEW_COLUMNS data dictionary view
"SALES_CUBE_CROSS_OVER_LINEAR_R" is the object name found using AWM OLAP Worksheet
Now try creating Measure "Cross Over Linear Regression 1" (Logical Name: SALES_CUBE.CROSS_OVER_LINEAR_REGRESSION_1)
"CROSS_OVER_LINEAR_REGR_1" is COLUMN_NAME value in SALES_CUBE view and in ALL_CUBE_VIEW_COLUMNS data dictionary view
"__AW_GENERATED_164" is the object name found using AWM OLAP Worksheet
I think AWM needs to be a little smarter in the way Object names are generated for measures/attributes.
Possible AWM solution for this would be to restrict the Measure Name to 30 characters that includes the Cube Name length. User can then utilize the Short Label, Long Label and Description fields to enter proper descriptions.

Answer 1

Although the physical AW object names are not shown in the data dictionary views in 11g, they are available through the Java OLAP API as of release 11.1.0.7.
For example, many of the physical names of the AW object underlying a logical (i.e. AWM or USER_CUBE_DIMENSIONS) dimension can be found from the class
oracle.olapi.metadata.deployment.AWPrimaryDimensionOrganization
E.g.
The name of the main AW dimension can be found using
public final String getAWDimensionName()
The name of the parent relation is
public final String getParentRelationName()
The name of the hierarchy dimension is
public final String getHierarchyListName()
To navigate from a logical dimension to the organization object you can do the following.
MdmPrimaryDimension myDim = ...;
AWPrimaryDimensionOrganization org = (AWPrimaryDimensionOrganization) myDim.getOrganization();
Other physical object names can be located in other classes in the oracle.olapi.metadata.deployment package. This methods are public and supported, but do not appear in the JavaDoc. I don't know if they will be documented at any stage and I know of no immediate plans to make these objects visible through the data dictionary views.
