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...
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...
Object-oriented database systems There has been considerable interest in recent years in the development of object-oriented database systems, encouraged to a large extent by the use of object-oriented programming languages. It is beyond the scope of this book to examine such a complex topic asob...

DB-Engines Ranking of Object Oriented DBMS trend chart The DB-Engines Ranking ranks database management systems according to their popularity. The ranking is updated monthly. This is a partial list of the complete ranking showing only object oriented DBMS. ...
1 Object-oriented DBMS integrated a variety of (81) data types-such as business procedures, graphics, pictures, voice and annotated text. Object orientation also makes a (82) to application development efficiency. It makes the data, functions, attributes, and relationships an integral part of the...
wever, the data management functionality for this field is not provided by general-purpose DBMSs. Therefore, we propose a data model of a specialized Time Series Mana- gement System (TSMS) which accounts for these needs. The model is centered around an object-oriented kernel ...
Synonyms ODB (object database);OODB (object-oriented database);ORDB (object-relational database) Definition An object data model provides support for objects as the basis for modeling in a database application. An object is an instance of a class, which is a complex type specification that ...
Abstract This paper presents an object-oriented data model for an image database. The formal presentation of the model stems from an analysis of the domain of remotely sensed radar images of the Arctic ice. The data model maintains the distinction between generic spatial attributes and representatio...
