By being well acquainted with the relational model and by noting the similarities and differ- ences between the two approaches to data modeling, designers will be able to turn into ac- count and differdnce make use of the already acquired experience as an important basis for under- standing and learning the methodology of designing object oriented databases.

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. At the time if designers know the similarities and differences between these two approaches they have the possibility to convert a relational model into an object oriented model and inversely.
