Unformatted text preview: Rule Development for Active Database Systems DISSERTATION DER WIRTSCHAFTSWISSENSCHAFTLICHEN FAKULTÄT DER UNIVERSITÄT ZÜRICH zur Erlangung der Würde einer Doktorin in Informatik vorgelegt von ANCA VADUVA aus Rumänien genehmigt auf Antrag von PROF. DR. KLAUS R. DITTRICH PROF. DR. HELMUT SCHAUER April 1999 Die Wirtschaftswissenschaftliche Fakultät, Abteilung Informatik, gestattet hierdurch die Drucklegung der vorliegenden Dissertation, ohne damit zu den darin ausgesprochenen Anschauungen Stellung zu nehmen. Zürich, den 9. Dezember 1998 Der Abteilungsvorsteher: Prof. Dr. P. Stucki To my mother and Anne-Marie Acknowledgements First, I would like to thank my referees Prof. Dr. K. R. Dittrich and Prof. Dr. H. Schauer. Prof. Dittrich gave me the opportunity to work on this exciting subject under his competent super-vision. He generously supported the learning process and the maturing of the ideas presented in the following. Prof. Schauer allowed me to be his assistant and gave me the encouragement and the freedom I needed to complete this thesis. Special thanks go to Dr. Stella Gatziu for countless invaluable discussions and constructive comments. She tirelessly guided and motivated me through all the stages of this thesis. I am grateful for the time and energy she devoted to the supervision of this work. Further thanks go to all my colleagues at the institute for providing an excellent working environment, especially to Hans Fritschi and Athanasious Vavouras for fruitful and inspiring discussions and to Stefan Joos and Stefan Berner for their helpful observations regarding the software engineering aspects of this thesis. The hints of Philipp Ackermann and Martin Dürst have been an enormous help in the struggle through the undocumented ET++. Will Harris generously accepted to do the proofreading of the manuscript. This work could have not been started without the two years grant of the Migros Genossen-schaft and the financial aid of the former Ost-Europa Fond at the University Zurich. I also greatly appreciate the financial support from Heinrich, Margrit and Kathrin Huber that came when I needed it most. Special thanks go to my family and my friends, Anne-Marie and Caspar Reinhart, for their love, understanding and encouragement. They have been a constant source of joy and strength during the ups and downs of the last years. Abstract Active database management systems promise to provide an effective integration of data-base concepts with the rule paradigm. Their strength resides in the centralized representa-tion of real-world semantics in form of rules instead of hiding and replicating them in application programs. However, despite their incontestable advantages, active database management systems are not widely used in practice. One of the reasons is the lack of sup-port for application development. This thesis analyzes specific needs of support and propos-es solutions, finally materialized as tools, for assisting the process of active application...
