PREFACE
At the end of 1992 Prof. Lev Tenenbaum,from the Institutefor Control Science in Moscow, took the initiative to organize a school of two weeks, "Advances in Database Systems, Implementations and Applications", in cooperation with CISM and Unesco. CISM is the International Centre for Mechanical Sciences in Udine (Italy). For already more than twenty years it organizes schools and courses, with the purpose to favour the exchange of ideas and experiences among experienced and young scientists all over the world. Lev asked me to coordinate the school together with him. From then on we had a fruitful cooperation, which resulted in the final program of the school which was held in Udine September 13-24,1993. Advanced information technology is pervasive in any kind of human activity science, business,finance, management and others - and this is particularly true for database systems. Both database theory and database applications constitute a very important part of the state of the art of computer science. Meanwhile there is some discrepancy between different aspects of database activity. Theoreticians are sometimes not much aware of the real needs of business and industry; software specialists not always have the time or the opportunity to get acquainted with the most recent theoretical ideas a
