The book edited by Bellahsene, Bonifati and Rahm provides an overview of the ways in which the schema and ontology matching and mapping tools have addressed the above requirements and points to the open technical challenges. The contributions from leading experts are structured into three parts: large-scale and knowledge-driven schema matching, quality-driven schema mapping and evolution, and evaluation and tuning of matching tasks. The authors describe the state of the art by discussing the latest achievements such as more effective methods for matching data, mapping transformation verification, adaptation to the context and size of the matching and mapping tasks, mapping-driven schema evolution and merging, and mapping evaluation and tuning. The overall result is a coherent, comprehensive picture of the field

This book constitutes the refereed proceedings of the 6th International XML Database Symposium, XSym 2009, held in Lyon, France, in August 2009 in conjunction with the International Conference on Very Large Data Bases, VLDB 2009. The 8 revised full papers together with 7 short paper were carefully reviewed and selected from 26 submissions. Covering all current aspects of core database technology for XML data management, XML and data integration, and development and deployment of XML applications, the papers are organized in topical sections on XML twig queries, query execution, xml document parsing and compression, XQuery and XML transaction management and schema design.

The Extensible Markup Language (XML) is playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere. The database c- munity is interested in XML because it can be used to represent a variety of data f- mats originating in different kinds of data repositories while providing structure and the possibility to add type information. The theme of this symposium is the combination of database and XML te- nologies. Today, we see growing interest in using these technologies together for many Web-based and database-centric applications. XML is being used to publish data from database systems on the Web by providing input to content generators for Web pages, and database systems are increasingly being used to store and query XML data, often by handling queries issued over the Internet. As database systems incre- ingly start talking to each other over the Web, there is a fast-growing interest in using XML as the standard exchange format for distributed query processing. As a result, many relational database systems export data as XML documents, import data from XML documents, provide query and update capabilities for XML data. In addition, so-called native XML database and integration systems are appearing on the database market, and it’s claimed that they are especially tailored to store, maintain and easily access XML documents.

These are the refereed proceedings of the 8th International Conference on Object-Oriented Information Systems, OOIS 2002 held in Montpellier, France, in September 2002.

CAiSE 2008 marked the 20th edition of the International Conferences on Advanced Information System Engineering, continuing the series' success since its inception. This success is largely due to its evolution alongside the growing significance of information systems in economic development. Since the first conference in 1978, organized by Arne Sølvberg and Janis Bubenko, CAiSE has effectively tracked and often anticipated pivotal changes in the field. Modern businesses and IT systems now navigate an increasingly complex environment marked by openness and rapid change, leading to greater diversity in business operations. The surge in information technologies has resulted in a plethora of languages, platforms, devices, standards, and products, necessitating that enterprises effectively manage these dynamics. To achieve sustainable development in their information systems, organizations must adapt to these challenges. Over the years, CAiSE researchers have confronted these transformations, and the conferences have served as a vital platform for presenting and discussing significant scientific findings. CAiSE remains central to these evolving processes, promoting innovative design and evaluation methods, developing new technologies tailored to information systems, and creating novel models, all under rigorous scientific scrutiny.
