I'm curious, do you know of any DBSM which store the DDL for a table? Reason being why this generally is not done is that schema-evolution either will outdate the DDL text very quickly, or cause a maintenance nightmare for DBMS developers.
Most systems I know leave it to tooling to reverse engineer the current, up to date, DDL for a table (and other objects) from the data dictionary.
