[dtp-dev] SQL Model Question - Column Data Types

[rcernich@xxxxxxxxxx]

Hey all,

I've got another SQL model question.

In the column element, what is the distinction between DataType,
ReferenceType and ContainedType?

My assumption would be that the ReferenceType should be a
ReferenceDataType, ContainedType would be a PredefinedDataType and DataType
would be a UserDefinedDataType?  However, ReferenceType is a
UserDefinedType, which is not a parent of ReferenceDataType;  ContainedType
could be either a ReferenceDataType or a PredefinedDataType; and DataType
could be any of the three.

Thanks in advance for any insight.
