Efficient XML Updates

With the rapidly evolving XML technology and thereby ever-increasing number of XML documents, the importance of providing efficient tools for managing these enormous amounts of data is rising every day. Native XML database systems are such tools. Like other XML database systems they need indices in order to provide efficient and fast access to the data. These indices represent redundant data structures in the database and therefore have to be kept consistent, whenever the underlying base data is manipulated. Updating fragments of an XML document with automated, transparent, and efficient index maintenance is the central theme of this book. Author Harald Burger first analyses the two most prominent existing proposals for XML updates, namely the W3C's proposed extension of XQuery with operations for data manipulation and XUpdate. He then introduces an efficient and simple way to keep the indices in an XML DBMS consistent: the Simple Update API for the native XML database management system Infonyte DB

Efficient Partitioning and Indexing of XML Data

XML is rapidly becoming the Internet standard for data representation and exchange. As a result, the number and size of XML documents is growing very fast. Large XML documents take more time to process and more time to do backup and recover. Hence, the efficient management of XML data is essential. Partitioning data is one way to process and efficiently manage a large database. Nearly all research studies have concentrated on optimizing query processing and indexing XML documents. Little work has been done on partitioning XML data. In this book, we are proposing a storage system called Partitioned and Indexed XML Storage System PIXSS which partitions and indexes large XML documents into smaller XML documents. PIXSS also includes new algorithms, which process queries on partitioned XML data. Our experimental results show that XML documents partitioned by PIXSS outperform those that are not partitioned.

Efficient Approaches for Querying XML Data

With the emergence of the World Wide Web and online businesses, business XML databases are increasingly being queried directly by users. This book focuses on three aspects related to querying of XML data, as follows: (1) Improving accuracy of XML keyword queries by modeling the contexts of XML elements. Most current research is focused on building relationships between data elements based solely on their labels and proximity to one another, while overlooking the contexts of the elements. This may lead to erroneous results. This book presents different context-driven techniques that avoid this problem. (2) Enhancing XML-based personalized search by using group profiling to determine individual preferences. Group profiling can be an efficient retrieval mechanism, where a user profile is inferred from the profile of the social groups to which the user belongs. A social group is defined based on ethnic, cultural, religious, or other characteristics. (3) Improving performance of distributed XML querying by caching of frequently-used query results. For each of these areas, we developed formal concepts and algorithms that lead to the improved accuracy and performance.

Storing and Querying XML

XML has emerged as the standard for representing and exchanging data on the World Wide Web. It is critical to have efficient mechanisms to store and query XML data to exploit the full power of this new technology. Several researchers have proposed to use relational databases to store and query XML data. The main challenge of this approach is that, one needs to resolve the conflict between the hierarchical nature of the XML data model and the flat nature of the relational data model. This book covers an efficient mapping system, called XML2REL, for storing and querying XML documents using relational databases in the presence of an XML schema (DTD). XML2REL requires three main mappings from XML to relational which are schema mapping, data mapping and query mapping. The XML-to-Relational mapping system introduced in this book should be useful to students, instructors, scientists and IT professionals who want to get full advantages of a mature relational database system to process large sizes of XML data. This book will also shed light for those who are interested in research related to XML data management.
