Condition: Good. Former library book; may include library markings. Used book that is in clean, average condition without any missing pages.
Condition: As New. This book presents a coherent suvey on exciting developments in database semantics. The origins of the volume date back to a workshop held in Prague, Czech Republic, in 1995. The nine revised full papers and surveys presented were carefully reviewed for inclusion in the book. They address more traditional aspects like dealing with integrity constraints and conceptual modeling as well as new areas of databases; object-orientation, incomplete information, database transformations and other issues are investigated by applying formal semantics, e. g. the evolving algebra semantics.

First Edition
Softcover. Condition: neu. 1. Auflage. Forschungsergebnisse zur Informatik, Band 13 140 pages. Joining ideas from database theory and logic programming leads to the theory of deductive databases. In addition to the data stored in a database (extensional facts), a deductive database stores rule based knowledge concerning parts of the real world which are modeled by the system. A deductive database management system (DDBMS) consists of two parts: 1) An arbitrary database management system and 2) a deduction mechanism that uses extensional as well as intensional facts and rules for deducing new data (intensional facts). Since rules can be seen as a declarative (programming, query) language, one of the main serious problems arising from logic programming and deductive databases is to find a (constructive) semantics which coincides with the user's intuitive meaning of the rules. The aim of this work is to introduce a Petri net semantics for logic programs and deductive databases which is more constructive than any currently known semantics. Logic programs and deductive databases are transformed into a Petri net class whose elements are called, according to their dynamical behaviour, fixpoint nets. The problems of non-monotonic reasoning are expressed by means of generalized conflict situations in fixpoint nets. The semantics of a logic program or a deductive database is defined by means of logical consequences of a set of (possibly three-valued) models, which can be generated from the saturated marking of the program's Petri net representation. It is shown that for stratified normal programs and for positive disjunctive programs the Petri net semantics coincides with the perfect model semantics and the Minker/Rajasekar semantics respectively.

Taschenbuch. Condition: Neu. Neuware -This book constitutes the thoroughly refereed post-proceedings of the Second International Workshop on Semantics in Databases, held in Dagstuhl Castle, Germany, in January 2001. The 10 revised full papers presented together with an introduction by the volume editors were carefully selected during two rounds of reviewing. Among the aspects of database semantics discussed are semantic constraints, paraconsistency, logic foundations of databases, ER modeling, type hierarchies, null values, consistency enforcement, logic-based pattern languages, and semantic classification of queries. Among the classes of databases dealt with are deductive databases, relational databases, distributed information systems, and tree-structured data.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.
