A Common Framework for Classifying and Specifying Deductive Database Updating Problems
نویسندگان
چکیده
In this paper we propose two interpretations of the event rules [Oli91] which provide a common framework for classifying and specifying deductive database updating problems such as view updating, materialized view maintenance, integrity constraints checking, integrity constraints maintenance, repairing inconsistent databases, integrity constraints satisfiability or condition monitoring. Moreover, these interpretations allow us to identify and to specify some problems that have received little attention up to now like enforcing or preventing condition activation. By considering only a unique set of rules for specifying all these problems, we want to show that it is possible to provide general methods able to deal with all these problems as a whole.

Classification and Specification of Update Problems*
Deductive databases are based on deductive rules (views) which define the common knowledge shared by different users by allowing to deduce new facts (derived or view facts) from base facts explicitly stored in the database. Deductive databases use logic programming as a base language and generalize relational databases by overcoming the limitations of relational languages in the definition of c...
متن کاملIntegrated Treatment of Updates in Deductive Databases: the FOLRE Project (extended abstract)
We review in this paper both a framework for integrating the treatment of advanced update problems in deductive databases and the architecture of the FOLRE deductive database management system prototype, which extends the basic updating facilities provided by current deductive database systems. The distinguishing feature of our approach is the underlying integrative framework used to specify an...
متن کاملFOLRE: A Deductive Database System for the Integrated Treatment of Updates
We present in this paper both a novel theoretically well-founded framework for integrating the treatment of advanced update and rule enforcement problems in deductive databases and the architecture of a new deductive database management system based upon such a framework. Our results extend the query-processing and basic updating functionalities provided by current deductive database systems wi...
متن کاملA Framework for Deductive Database Design im Decision Support Systems
A three-level framework for design and implementation of deductive database management systems is described. The three levels consist of the abstraction, for abstracting the real world semantics, the language, for man-machine communication, and the environment, for specifying the hardware/software environment. This framework is applied to some representative systems. Based on the results, an ar...
متن کاملSemantic foundations for the view update problem
We present a declarative framework for updating views over indefinite databases, that is, databases with null values. The framework follows the standard database approach, which allows for a unique null constant. As the main contributions of the paper, we introduce the concept of an indefinite deductive database as a formal representation of a view over an indefinite database, propose a semanti...
