Object-oriented database management systems (OODBMS) are used to imple ment and maintain large object databases on persistent storage. Regardless whether the underlying database model follows the object-oriented, the rela tional or the object-relational paradigm, a key feature of any DBMS product is...
As the power of application software has grown, breakthroughs in database technology have been achieved to meet these new demands. Organizations now face the decision of which technology to use, and this choice is not an easy one. What is needed is a model that can be used to structure ...
Formally, an object-oriented database model is a tuple (CS,AS,RS,O,M,S), in which CS is a finite set of classes, AS is a finite set of attributes, RS is a finite set of relationships, O is a finite set of objects, M is a finite set of methods, and S is a finite set of...

, object-oriented programming (OOP) languages, such as C++ and Java, provide a formal set of rules for creating and managing objects. The data are stored in a traditional relational database or in an object database if the data have a complex structure. SeeO-R mappingandobject database....
object DBMS) object databaseA database that is managed by an object-oriented database management system (ODBMS). Object databases are closely aligned with a particular object-oriented programming language and enable the data in the objects to be persistently stored without requiring conversion to a...
An OVUM report published in 1988 predicted that database systems adhering to an object-oriented data model as opposed to a relational data model would overtake relational database systems by the mid 1990s (OVUM, 1988). Although this clearly has not happened, there is no doubt that object-orien...
This DBMS can also be used for knowledge representation, and is well-suited to the design of queries in natural language. The system VORAS is an object-oriented DBMS developed from a specific model of representation called the Property Driven Model (PDM). A user may write a query in natural...
