Database support for architectural applications requires appropriate tools for managing graphical and textual informations. In this paper we propose the use of an object oriented database providing uniform access to diverse and autonomous information related to an architectural project. The presented approach supports the integration of heterogeneous data, some of which are under the control of a CAD system.

As graph transformation systems evolve, they are used to solve complex problems and the resulting specifications tend to get larger. With specifications having more than one hundred pages they suffer from the same problems as large applications written in programming languages like C++ or Java do. Under the term programming in the large many different concepts have been developed to aid the solution of these problems. However, most graph transformation systems lack support for the problems.
With the introduction of UML-like packages, the PROGRES environment provides basic support for specifying in the large. Now that packages have been used in many different specifications, their shortcomings have become obvious. Additionally, our experience with large specifications showed that packages alone are not sufficient and therefore we have developed concepts for modularizing and coupling specifications. Our graph database provides the runtime-support required by these concepts.
This course is a survey of the principles of information retrieval and their application to information systems and services. The course emphasizes models of user information seeking behavior and human information processing, and their relationships to retrieval models in information systems. It explores the fundamental processes of description, classification, information structures, database models, and intermediation as those processes are reflected in information systems of all types, including, libraries. In addition, the course explores various information systems to illustrate principles.
Information Systems Development (ISD) progresses rapidly, continually creating new challenges for the professionals involved. New concepts, approaches and techniques of systems development emerge constantly in this field. Progress in ISD comes from research as well as from practice. The aim of the Conference is to provide an international forum for the exchange of ideas and experiences between academia and industry, and to stimulate exploration of new solutions.
