Nexus is a research project with the aim of developing an open
platform for context aware systems. Context aware systems do
consider the user position when retrieving the respective
information from the system.
The project is based on a federated object oriented database which
allows relationships between objects. The relationship is
represented by an independent object storing the identifiers and the
locators of the referenced objects. However, yet there is no
information stored in some place to find this relationship when the
search is triggered at one of the referenced objects.
The following work presents and compares several approaches on how
to find all those objects referencing an object of particular
interest. Furthermore, the referencial integrity of the developed
models is examined. The models are based on return references,
centralized or distributed indexes, or proximity.
