Function materialization in object bases  91
Function materialization in object bases
收藏 引用
1991 ACM SIGMOD International Conference on Management of Data, SIGMOD 1991
作者: Kemper, Alfons Kilger, Christoph Moerkotte, Guido Universität Karlsruhe Fakultät für Informatik KarlsruheD-7500 Germany
We describe function materialization as an optimization concept in object-oriented databases. Exploiting the object-oriented paradigm-namely classification, object identity, and encapsulation-facilitates a rather easy... 详细信息

Workshop on Parallel Database Systems, 1990
作者: Apers, Peter M. G. Hertzberger, L.O. Hulshof, Ben J. A. University of Twente Netherlands University of Amsterdam Netherlands Philips Research Laboratories Netherlands
The design of a large database management system on top of an object-oriented platform which is implemented on a tightly coupled multiprocessor system requires a large number of design decisions. There exist no method... 详细信息

5th European Conference on object-oriented Programming, ECOOP 1991
作者: Medeiros, Claudia Bauzer Pfeffer, Patrick DCC-IMECC-UNICAMP CP 6065 CampinasSP13081 Brazil Department of Computer Science University of Colorado BoulderCO80309-0430 United States
Integrity maintenance in object-oriented systems has so far received little attention. This paper is an attempt to fill this gap. It describes a mechanism for maintaining integrity in an object- oriented database, imp... 详细信息

10th ACM SIGACT-SIGMOD-SIGART Symposium on Principles of Database Systems, PODS 1991
作者: Van Den Bussche, Jan Paredaens, Jan Dept. Math. and Comp. Science Universiteitsplein 1 AntwerpB-2610 Belgium
We provide a general framework to study the notion of abstraction in pure object-oriented database models with query languages based on object creation. Abstraction is the key operation to express structured values li... 详细信息

Behavior analysis of object-oriented databases: Method structure, execution trees, and reachability  3rd
收藏 引用
3rd International Conference on Foundations of Data Organization and Algorithms, FODO 1989
作者: Hull, Richard Tanaka, Katsumi Yoshikawa, Masatoshi Computer Science Department University of Southern California Los AngelesCA90089-0782 United States Department of Instrumentation Engineering Faculty of Engineering Kobe University Rokkodai Nada Kobe657 Japan Institute of Computer Sciences Kyoto Sangyo University Kamigamo Kita-ku Kyoto603 Japan
A theoretical model for analyzing the behavior of method execution in object-oriented databases (OODBs) is introduced and used to study issues of reachability, nontermination, and well-typedness in the context of rest... 详细信息

Evaluation and optimization of complex object selections  2nd
收藏 引用
2nd International Conference on Deductive and object-oriented databases, DOOD 1991
作者: Van den Bussche, Jan Dept. Math. & Comp. Science Universiteitsplein 1 AntwerpB-2610 Belgium
We provide a general framework for declarative selection operations for complex object databases, based on the safe calculus for complex objects. Within this framework, we consider a class of "single pass-evaluab... 详细信息

MIT-JSME Workshop on Computer-Aided Cooperative Product Development, 1989
作者: Skarra, Andrea H. Brown University Department of Computer Science ProvidenceRI02192 United States
We describe a model of transactions and concurrency control that supports cooperative task and data sharing among users. The model augments traditional correctness criteria, such as global consistency for individual t... 详细信息

A comparison between deductive and object-oriented database systems  2nd
收藏 引用
2nd International Conference on Deductive and object-oriented databases, DOOD 1991
作者: Ullman, Jeffrey D. Stanford University United States
The author will not pretend to be unbiased in the matter of comparing the deductive and object-oriented approaches to new database systems;he believes that despite some important concepts originating with the object-o... 详细信息
