متن کاملIncremental Maintenance for Materialized Views over Semistructured Data
Semistructured data is not strictly typed like relational or object-oriented data and may be irregular or incomplete. It often arises in practice, e.g., when heterogeneous data sources are integrated or data is taken from the World Wide Web. Views over semistructured data can be used to lter the data and to restructure (or provide structure to) it. To achieve fast query response time, these vie...
متن کاملQuery Rewriting using Semistructured Views
We consider the problem of rewriting semistructured queries using semistructured views. Given a client semistructured positive non-recursive query and a set of semistructured views, the algorithm nds a rewriting query that is equivalent to the client query and accesses only the views. Our solution is based on appropriately generalizing well understood techniques such as containment mappings and...
متن کاملIndexing and Querying Semistructured Data Views of Relational Database
The most promising and dominant data format for data processing and representing on the Internet is the Semistructured data form termed XML. XML data has no fixed schema; it evolved and is self describing which results in management difficulties compared to, for example relational data. XML queries differ from relational queries in that the former are expressed as path expressions. The efficien...
متن کاملMaintaining Semantics in the Design of Valid and Reversible SemiStructured Views
Existing systems that support semistructured views do not maintain semantics during the process of designing views. Thus, there is no guarantee that the views obtained are valid and reversible views. In this paper, we propose an approach to designing valid and reversible semistructured views. We employ four types of view operators, namely, select, drop, join and swap operators, and develop a se...
