Emphasis is put on implications of this concept for an object model ...

The paper focuses on the problem of introducing dynamic object roles into the UML (Unified Modeling Language) class diagram, which is used to present object-

Research paper thumbnail of Storing Data in KDD Systems /from Inlen 3.0 to InlenStar. Evolution of Database/

A set of selected software systems is analysed. Then a new system called InlenStar is briefly presented and its structure of database is widely discussed, as an example of the structure of knowledge database.

Research paper thumbnail of Dynamic Object Roles -- Adjusting the Notion for Flexible Modeling

International Database Engineering and Application Symposium, 2004

The conceptual modeling of real-life situations often requires expressing some kind of multiple, ... more The conceptual modeling of real-life situations often requires expressing some kind of multiple, multi-aspect or dynamic specialization. On the other hand, multiple or dynamic inheritance impose troublesome anomalies and thus are sporadically and not fully supported by development tools. In this paper we suggest a new approach to the concept of dynamic object roles, capable of expressing all the mentioned
