Efficient XML Updates- Index-Aware Updates for a Native XML Database System

With the rapidly evolving XML technology and thereby ever-increasing numberof XML documents the importance of providing efficient tools for managingthese enormous amounts of data is rising every day. Native XML databasesystems are such tools. Like other XML database systems they need indicesin order to provide efficient and fast access to the data. These indicesrepresent redundant data structures in the database and therefore have to bekept consistent whenever the underlying base data is manipulated. Updatingfragments of an XML document with automated transparent and efficientindex maintenance is the central theme of this book.Author Harald Burger first analyses the two most prominent existingproposals for XML updates namely the W3C's proposed extension of XQuerywith operations for data manipulation and XUpdate. He then introduces anefficient and simple way to keep the indices in an XML DBMS consistent: theSimple Update API for the native XML database management system InfonyteDB.This book is addressed to professionals involved in XML and database development.It is also directed towards researchers in the XML area and beginninggraduate or advanced undergraduate students of computer science.
