An Overview of Fragmentation Design for Distributed Xml Databases
XML is a standard of data exchange between web applications such as in e-commerce, elearning and other web portals. The data volume has grown substantially in the web and in order to effectively retrieve or store these data, it is recommended to be physically or virtually fragmented and distributed into different nodes. Basically, fragmentation design contains of two parts: fragmentation operat...
متن کاملDistributed XML Repositories: Top-down Design and Transparent Query Processing
XML is increasingly used not only for data exchange but also to represent arbitrary data sources as virtual XML repositories. In many application scenarios, fragments of such repositories are distributed over the Web. However, design and query processing models for distributed XML data have not yet been studied in detail. The goal of this paper is to study the design and management of distribut...
متن کاملDistributed Reactive XML
XML-centric models of computation have been proposed as an answer to the demand for interoperability, heterogeneity and openness in coordination models. We present a prototype implementation of an open XML-centric coordination middleware called Distributed Reactive XML. The middleware has as theoretical foundation a general distributed extensible process calculus inspired by the theory of Bigra...
متن کاملDistributed XML Database Systems
Invention of XML as a universal standard for data representation triggered enormously wide efforts for its adaptation into almost every IT activity. Databases took one of the focusing places of the XML research. This paper investigates the development path of XML from its origins to its current place in distributed database systems. Through enumeration of features and analysis of the problems r...
متن کاملDistributed CBR using XML
CBR (case-based reasoning) has considerable potential for developing intelligent assistants for the World Wide Web. Several case-based intelligent applications already exist on the web but these applications follow a thin client model with the intelligence located at the server side. In this paper we explore the advantages of making these applications more distributed. We illustrate the kinds o...
