Focus: Object Orientated Databases
The object-oriented label is in common use. It is applied
to programming. analysis and design methodologies as well as databases.
Thus, there is a certain amount of confusion concerning this term. To make
matters worse from our point of view, there is no standard object-oriented
database model. At the present time, there is no universally accepted,
abstract, formally developed object data model which can be used as the
basis of a database. Hence. you will find OODBs treated in different ways in
different books although there is general agreement on the basic ideas. This
chapter will cover the main principles behind the object-oriented idea and
give some examples of how an 00 database may be implemented.
