Normalized data are separated from processing and the processing corresponding to satisfying informational requirements need not be totally pre-defined, thus accepting ad-hoc requirements too. Remember me on this computer. RDBMS support a small, fixed collection of data types eg.

ORDBMS is an attempt to extend relational database systems to provide a bridge between the relational and object-oriented paradigms. Help Center Find new research papers in: Can someone explain this clearly.
