This paper proposes an historical model integrating the main functionalities needed by an object DBMS to cope with the data historical dimensions.

Vincenzo Lattanzio,Angela Maria Guerrieriontexts. During the program development, collaboratively working programmers address different contexts and do not conflict with each other. The programming environment supports awareness and communication mechanisms among them. During the program execution, only one context is active. It may, however, be changed dynamically at program run-time.

Antonio Giarra-Zimmermann,Bert Eichhornduced into the system declaratively. Methods of supporting new composite event expressions are described, and comparisons with other relevant approaches are also conducted. A prototype of ADOME-II has been constructed, which has as its implementation base an ordinary (passive) OODBMS and a production rule base system.

Hans-Jürgen Bieling,Johannes Jäger to join the advantages of both the declarative expression of the deductive approach and the automatic maintenance of the active approach. We aim at defining a declarative language to express mono-valued, multi-valued and recursive derivations in an object-oriented database context, and maintaining these derivations using a dependency graph.
