Object-Oriented Database Systems: The Notion and the Issues - Dittrich () Citation Context ...he PUP framework to perform disk I/O using “PUP toDisk” and “PUP fromDisk”. This use of the PUP framework is a lightweight version of the object persistence schemes found in object-oriented...
Since half a decade or so, object-oriented database systems have become an extremely hot topic of database research and development. At many places all over the world, people work on individual aspects or complete system prototypes. Already, some systems have even reached the marketplace. Howeve...
One of the basic functionalities of database management systems (DBMSs) is to be able to process declarative user queries. The first generation of object-oriented DBMSs did not provide declarative query capabilities. However, the last decade has seen significant research in defining query models (...
In this paper, we propose an approach and basic constructs to realize a fuzzy database processing capability on an Object-Oriented Database (OODB) system. The proposed approach can manage several types of uncertainties: (1) uncertain objects, (2) uncerta
Parallel Query Processing in Object-Oriented Database Systems Because of the wide acceptance of object-oriented database systems, query processing and indexing have become an important factor in the success of object-oriented database systems, especially when we deal with composite objects. To tack....
With the increasing use of the object-oriented database software, system performance has become an important issue in the system procurements and evaluation process. It is vital to understand and predict the functionality and performance characteristics of the systems to be procured in the real world...
Query Languages for Object-Oriented Database Systems: Analysis and a Proposal This paper discusses the problem of query languages for object-oriented database systems. We first discuss the general problem of designing such a language. Then we restrict ourselves to the specific context of the O 2...
Object-oriented data bases are fast gaining in popularity, especially with advanced applications like computer aided design (CAD) and multimedia data bases (MMDB). The modeling techniques required by these applications cannot be met by conventional data base systems. The semantic richness of the ob...
object-oriented database system, FOOD, is presented. We emphatically describe the data model, application programming language, query language, authorization model, and scheme management of FOOD. The implementation approach and function modules of FOOD are also introducted. We end this paper with our...
A Flexible Class Hierarchy Locking Technique in Object-Oriented Database Systems In this paper, we present a locking-based concurrency control scheme for object-oriented databases (OODBs). Our scheme deals with class hierarchy which is an important property in OODBs. Our scheme is based on so ...
