Towards Deductive Object Databases

by Elisa Bertino, Giovanna Guerrini, Danilo Montesi - IN PROOCEDINGS OF ECOOP'95 , 1994
"... This paper proposes a new approach to model deductive object databases. Each object database is described by means of a Datalog language extended with extensional updates, called U-Datalog. Objects can change state and cooperate. We introduce an extension of U-Datalog to approach the problem of c ..."

Deductive and Object-Oriented Databases

by Serge Abiteboul , 1992
"... These notes were written for a tutorial in JICSLP (Washington, 1992) and are not intended to be a comprehensive survey of the field. We are concerned with dooD, i.e. deductive object-oriented databases (systems). We briefly review ooD systems (object-oriented database management systems) and ded ..."

Towards A Deductive Object-Oriented Database Language

by Serge Abiteboul - Data & Knowledge Engineering , 1990
"... A language for databases with sets, tuples, lists, object identity and structural inheritance is proposed. The core language is logic-based with a fixpoint semantics. Methods with overloading and methods evaluated externally providing extensibility of the language are considered. Other important iss ..."

in that success has been the existence of simple-to-use languages allowing the definition and manipulation of data. This has to be remembered while considering future generations of database systems. Object-oriented database systems are now being developed, e.g., [15, 12, 22, 39, 36]. An object-oriented approach

Deductive Object

by Elisa Bertino - Databases, Proceedings ECOOP’94 , 1994
"... • An access control system regulates the operations that can be executed on data and resources to be protected • Its goal is to control operations executed by subjects in order to prevent actions that could damage data and resources • Access control is typically provided as part of the operating sys ..."

Approaches to Deductive Object-Oriented Databases

by Alvaro A.A. Fernandes, Norman W. Paton, M. Howard Williams, Andrew Bowles , 1992
"... This paper is concerned with the problem of combining deductive and object-oriented features to produce a deductive object-oriented database system which is comparable to those currently available under the relational view of data modelling not only in its functionality but also in the techniques em ..."

Constraints in an Object-Oriented Deductive Database

by Yves Caseau , 1991
"... This paper relates our experience in integrating constraint resolution into an object-oriented deductive system. We motivate this work by showing that disjunctive information and global constraints fit naturally in an object-oriented model and are actually necessary to perform common tasks. We ident ..."

Representing Objects as Modules in Deductive Databases

by Burkhard Freitag - Proc. Second ICLP-Workshop on Deductive Databases and Logic Programming , 1994
"... In this paper an approach to the integration of object-orientation and deductive databases is presented. The underlying language is an extension of conventional deductive database languages and allows a very natural and uniform representation of classes and objects as modules. 1 Introduction In th ..."

Generic Methods in Deductive Object Databases

by Elisa Bertino, Giovanna Guerrini, Danilo Montesi , 1994
"... Deductive objects have been introduced in [3] to support declarative object specification in the database context taking advantage of the large body of results on Datalog-like language. However, the rigidity of logical languages does not reflect the flexible programming style of object-oriented syst ..."

Deduction and Deductive Databases for Geographic Data Handling

by A. I. Abdelmoty, M. H. Williams, N. W. Paton - Handling, Proc. Intl. Symposium on Advances in Spatial Databases 1993 (SSD'93 , 1993
"... . The representation of complex spatial domains in conventional databases suffers from fragmented representation of object structure, lack of instance-level spatial relationships, and the generation of large combinatoric search spaces in query analysis. The deductive capabilities provided by a d ..."

Managing Semistructured Data With Florid: A Deductive Object-Oriented Perspective

by Bertram Ludäscher, Rainer Himmeröder, Georg Lausen, Wolfgang May, Christian Schlepphorst , 1998
"... The closely related research areas management of semistructured data and languages for querying the Web have recently attracted a lot of interest. We argue that languages supporting deduction and object-orientation (dood languages) are particularly suited in this context: Object-orientation provid ..."
