描述This book constitutes the refereed proceedings of the 5th International Conference on Deductive and Object-Oriented Databases, DOOD‘97, held in Montreux, Switzerland, in December 1997. The 22 revised full papers presented in this book were selected from a total of 59 submissions. Also included are abstracts or full versions of three invited talks and three tutorials and six short presentations. The papers are organized in topical sections on materialized view maintenance, extending DBMs features, database updates, managing change in object databases, semantics of active databases, formal semantics, and new directions.

https://doi.org/10.1007/978-3-476-03675-9considered the incremental maintenance of deductive views defined by expensive database queries, including the transitive closure query. An interesting approach is to use only first-order queries in this maintenance, after small changes (e.g. one tuple insertions and deletions) to base relations. In

In exchange, the system maintains (redundant) views of the application data that help to minimize query response time. We understand views as functions of database objects and examine algebraic properties of these functions, in particular l

For instance, one can replicate auxiliary views of the base relations at the site where the views are materialized to ensure self-maintenance of the views. However, the previous approaches often lead to the replication of the entire base relations,

We propose a formalism in which rules are divided into two classes: “Defining rules” specify the existence of tuples in the relation, together with some of their attributes. “Refining rules” specify derived attributes of tuples tha
