The Workshop on Formal Methods in Databases and Software Engineering took place at Concordia University, Montreal, Canada, from the 15-16 May 1992. Most existing research tends to concentrate exclusively on formal methods in either databases or software engineering. This was the first in a proposed series of workshops specifically aimed at fostering interdisciplinary research between these two important fields. The workshop provided an opportunity for researchers and practitioners to discuss recent developments in an informal setting. Twelve papers were presented and many lively and constructive discussions were conducted. This volume contains selected papers from the workshop, which have been expanded and edited for publication. The theme of the workshop was explored through a variety of topics, including: transaction logic programming; modeling uncertainty and incompleteness in databases; concept learning and data mining; efficient deduction and induction in knowledge-base systems; proof management and verification; temporal and real-time databases; object-oriented VDM; software engineering environments and object charts. Formal Methods in Databases and Software Engineering brings together many topics of current interest in database and software engineering research. By combining these two complementary fields it provides new perspectives on various important issues. It will provide invaluable reading for researchers, practitioners and postgraduate students.
