Modifying the schema of a populated database is an expensive operation. We propose to use the non-classical transposed storage of an object database. The transposed storage avoids database reorganization and reduces the number of input/output operations in the context of schema evolution. Thus schema changes are not anymore costly operations. Consequendy immediate and physical propagation of schema changes can be supported. We extend the 007 benchmark with schema evolution operations and submit our F2 DBMS to this benchmark. The obtained results demonstrate the feasibility and performance of our approach.
