Querying object-oriented databases

by Michael Kifer, Won Kim, Yehoshua Sagiv - ACM SIGMOD INTERNATIONAL CONFERENCE ON MANAGEMENT OF DATA , 1992
"... We present a novel language for querying object-oriented databases. The language is built around the idea of extended path expressions that substantially generalize [ZAN83], and on an adaptation of the first-order formalization of object-oriented languages from [KW89, KLW90, KW92]. The language inco ..."

Security In An Object-Oriented Database

by James M. Slack
"... Much of the research in security for object-oriented databases follows the traditional lines of discretionary access control, mandatory access control, and multilevel secure database systems. In this position paper, our premise is that security and integrity can be implemented in the object-oriented ..."

Migration In Object-Oriented Database . . .

by C. Huemer, G. Kappel, S. Vieweg - SOFTWARE---PRACTICE AND EXPERIENCE, VOL. 25(10), 1065--1096 (OCTOBER 1995) , 1995
"... ... this paper is to fill this gap. The paper describes a framework for the migration of object-oriented database applications. Our approach is based on a detailed analysis of the involved database systems, of the application's database requirements, and of the resources available for the datab ..."

Concepts for Object-Oriented Databases

by Michael Dobrovnik, Johann Eder - In: Proceedings of the 4th International Symposium on System Research, Informatics and Cybernetics , 1993
"... We present a concept to introduce external models in object-oriented databases to regain the traditional three level architecture of database systems consisting of an internal, a conceptual and several external models. In contrast to other approaches our concept takes into account all traditional fe ..."

for Object-Oriented Databases

by Deborah Jing-Hwahwang February, Deborah Jing-hwa Hwang, Deborah Jing-hwa Hwang , 1994
"... Object-oriented databases havebeendeveloped to allow applications to store persistent data in the form of objects. As in conventional databases, object-oriented databases need to support queries that allow associative access to data by describing a property of the data of interest. In particular, th ..."

The Object-Oriented Database System Manifesto

by Malcolm Atkinson, François Bancilhon, David DeWitt, Klaus Dittrich, David Maier, Stanley Zdonik , 1989
"... This paper attempts to define an object-oriented database system. It describes the main features and characteristics that a system must have to qualify as an objectoriented database system. We have separated these characteristics into three groups: ffl Mandatory, the ones the system must satisfy in ..."

The FOOD Object-Oriented Database

by Erik Odberg, Svein Erik Bratsberg , 1990
"... In this paper, we present the FOOD Object-Oriented Database. This is done in the perspective of a general framework and motivation for Object-Oriented Databases. FOOD is fully Object-Oriented, essentially providing persistency for C++ objects. Additional features extending the C++ data model incl ..."

Constraints in Object-Oriented Databases

by Joachim Biskup, Torsten Polle , 2000
"... Normal forms in relational database theory, like 3NF or BCNF, are dened by means of semantic contraints. Since for these constraints sound and complete axiomatisations exist and, additionally, for some of these constraints the implication problem is decidable, computer aided database design is po ..."

is possible for relational data models. Object-oriented database theory lacks such normal forms, partly because neither a classication of semantic constraints nor sound and complete axiomatisations exist. In this work we present three classes of semantic constraints for object-oriented data models
