An RDBMS is a logical database management system which represents predicates and propositions as tables and rows, providing features to maintain consistency and to query a database to derive information from recorded data.

The project must be converted in relational and access tables in accordance with Diffdrence.

At the time if designers know the similarities and differences between these two ooddbms they have the possibility to convert a relational model into an object oriented model and inversely. The Join Operator refers data from separate tables.

Differfnce contrast, most OODBMS implementations directly support only binary relations via object attributes and references and very limited support, if any, for derivation of facts. The classes of objects directly represent the concepts of applications. Inheritance helps to reduce the redundancy of methods.
