In contrast, most OODBMS implementations directly support only binary relations via object attributes and references and very limited support, if any, for derivation of facts. As we all know a relational database is made While in a relational database the compoup of relations, who are sets of tuples, while nents of a tuple must be primitive types an object-oriented database is made up of strings, integer, real, etc. ORDBMS is an attempt to oodbmms relational database systems to provide a bridge between the relational and object-oriented paradigms.

Table 1 presents a comparison of ing information about each student, while a the main concepts used in object and relarelational database will contain a class called tional modeling of data.
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.
It is said that we have to do with an ajd of classes and not with an independence of data.

By being oodbmw acquainted with the relational model and by noting the similarities and differences between the two approaches to data modeling, designers will be able to turn into account and to make use of the already acquired experience as an important basis for understanding and learning the methodology of designing object oriented databases. 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 bftween recorded data.
RDBMS support a small, fixed collection of data types eg.
