Translating View Updates Using Inversion of Relational Algebra Translating View Updates Using Inversion of Relational Algebra
Views over databases have been studied in various directions for many years. Among these directions , translating view updates in terms of updates on the base relations BS81, IL83], and materialized views and their maintenance BLT86, CW91] have motivated many research eeorts. Nowadays, materialized views are nding increased research activity with applications in decision support which is releva...
متن کاملView Updates Translations in Relational Databases
Views over databases have been studied in various directions for many years. Among these directions, translating view updates in terms of updates on the base relations has motivated many research eeorts. In this paper, we propose a method for characterizing translations of view updates, based on the notion of inverse of a relational expressions. Moreover, we characterize two kinds of updates: (...
متن کاملA Relational View of Accounting Information Sharing
Today’s organizations are characterized by a network of relationships with various customers and suppliers. As such, the critical resources leading to competitive advantage may no longer reside within a firm’s own boundaries and instead be a part of the network of relationships. This perspective, known as the relational view of the firm, suggests that a firm’s critical resources may be embedded...
متن کاملA Logic Programming View of Relational Morphology
We use the more abstract term "relational morphology" in place of tile usual "two-level morphology" in order to emphasize an aspect of Koskenniemi's work which has been overlooked in favor of implementation issues using the finite state paradigm, namely, that a mathematical relation can be specified between the lexical and surface levels of a language. Relations, whether finite state or not, ca...
متن کاملA Relational View of Subgraph Isomorphism
This paper presents a novel approach to the problem of finding all subgraph isomorphisms of a (pattern) graph into another (target) graph. A relational formulation of the problem, combined with a representation of relations and graphs by Boolean functions, allows to handle the combinatorial explosion in the case of small pattern graphs and large target graphs by using Binary Decision Diagrams (...
