------------------------------------------------------------------------------
- The RDB DAS uses JDBC 
[http://java.sun.com/j2se/1.3/docs/api/java/sql/ResultSetMetaData.html 
ResultSetMetadata] to create the set of SDO Types used to construct the data 
graph returned as a result of a query.  JDBC provides an instance of ResultSet 
to return the data reulting from a query execution and this data is organized 
as rows of column values.  The associated !ResultSetMetadata provides 
information about the values.  For example, table name, column name, column 
type, etc are provided for each returned column value in the !ResultSet.
