Dear Wiki user,

- 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 returns the data resulting from a query as a set of rows of
column values.  The associated !ResultSetMetadata provides information about these values.
 For example, table name, column name, column type, etc. are all provided for each returned
column value.
