The market trends indicate that the next generation database technology will be dominated by object-relational systems. This shift to the new technology calls for visual modeling techniques to facilitate the design of object-relational database systems. Even though Unified Modeling Language (UML) is not currently equiped to manage this task, it can be extended for it.The paper defines design co...

This paper deals with a seldom studied object/oblique alternation phenomenon in Japanese, which. We call this the bump alternation. This phenomenon, first discussed by Sadanobu (1990), is similar to the English with/against alternation. For example, compare hit the wall with the bat [=immobile-as-direct-object frame] to hit the bat against the wall [=mobile-asdirect-object frame]). However, in ...

With the Object-Reference (ORef) approach, the traditional object-oriented model is extended with references to act as a canonical model. Our ORef model facilitates the storage of localised behaviour and provides a precise de nition for updating objects across distributed information systems. Both these characteristics are realised using an Object Pool connectivity mechanism that connects local...

A dedicated approach for the design and development of distributed software systems is outlined. The method may be used in combination with any standard object-oriented analysis and design method as far as static aspects are concerned. A new formalism based on extended Petri-Nets { so called Object Coordination Nets (OCoNs) { is used to describe the coordination of the behavior of a class on a ...

Object-relational database systems add object-oriented features to relational DBMS and allow the DBMS’s functionality to be extended to new application domains. For the important domain of fulltext retrieval and document management, we analyze whether current object-relational DBMS are already able to compete with specialized information retrieval (IR) systems. After discussing the main require...
