During the last few years, parallel object-relational database management systems have emerged as the leading data management technology on the market. These systems are extensible by user-defined data types and user-defined functionality for the data. This work focuses on the efficient parallel execution of user-defined functionality. The main contributions describe techniques to support data parallelism for user-defined scalar and aggregate functions and intra-function parallelism for the execution of a scalar function on a large object, and a new technology to provide extensibility with regard to new set-oriented database operations that can efficiently implement user-defined functionality in parallel object-relational database management systems.
The latest techniques and principles of parallel and grid database processing The growth in grid databases, coupled with the utility of parallel query processing, presents an important opportunity to understand and utilize high-performance parallel database processing within a major database management system (DBMS). This important new book provides readers with a fundamental understanding of parallelism in data-intensive applications, and demonstrates how to develop faster capabilities to support them. It presents a balanced treatment of the theoretical and practical aspects of high-performance databases to demonstrate how parallel query is executed in a DBMS, including concepts, algorithms, analytical models, and grid transactions. High-Performance Parallel Database Processing and Grid Databases serves as a valuable resource for researchers working in parallel databases and for practitioners interested in building a high-performance database. It is also a much-needed, self-contained textbook for database courses at the advanced undergraduate and graduate levels.
The role of data management becomes more and more crucial in a totally connected world. Having the right data at the right time at the right place is therefore one of the most challenging research issues we face in the coming years. This Festschrift volume is devoted to Hartmut Wedekind on the occasion of his 70th birthday and comprises a total of 18 articles discussing a broad spectrum of issues related to data management. All articles are (co-)authored by academic children and grandchildren of Hartmut Wedekind and therefore reflect the multifaceted selection of academic topics that he explored, discussed, and published on during his academic life. All articles are clustered into four different parts, focusing on motivation and modeling issues, infrastructural services, application design, and finally different applications. The scope of the articles reaches from visionary illustrations of data management in a connected world through core database techniques in the context of database caching, notification services, etc., to the design and description of data-intensive applications.
Provides developments and research, as well as current innovative activities in data warehousing and mining, focusing on the intersection of data warehousing and business intelligence.
The second edition of this bestselling title is a perfect blend of theoretical knowledge and practical application. It progresses gradually from basic to advance concepts in database management systems, with numerous solved exercises to make learning easier and interesting. New to this edition are discussions on more commercial database management systems.
A thorough presentation of query processing techniques in a broad range of database systems for advanced applications. Provides the most effective query processing techniques and ways to optimize the information retrieval process. Intended for database systems designers creating advanced applications.
This book constitutes the refereed proceedings of the 13th International Conference on Database and Export Systems Applications, DEXA 2002, held in Aix-en-Provence, France, in September 2002. The 89 revised full papers presented together with three invited papers and a position paper were carefully reviewed and selected from 241 submissions. The papers are organized in topical sections on Web, workflow, data warehouses and datamining, applications, XML, distributed systems, knowledge engineering, advanced databases, queries, information retrieval, and indexing.
The 14th DEXA 2003 International Conference on Database and Expert - stems Applications was held during September 1–5, 2003 at the Czech Technical UniversityinPrague,CzechRepublic.TheDEXAlineofconferenceshasalready gained its own reputation and respected position as a platform for the exchange of ideas among theoreticians and practitioners in the wider area of computer science, but mainly in the areas of database and knowledge-based technologies. Since DEXA 1993, which was held in Prague, DEXA has grown into a m- ticonference consisting of four more focused and specialized conferences besides DEXA itself, namely the DaWak conference, EC-Web conference, eGOV c- ference, and this year happening for the ?rst time, the HoloMAS conference. In addition, the DEXA workshop is a special event o?ering enough space for specialized discussion, and acting – in a certain sense – as an incubator for new conferences. The DEXA conference itself is growing in volume and quality each year. This time there were 236 papers submitted and reviewed and the program committee selected 91 of the best papers to be included in this volume. Each of the subm- ted papers was carefully reviewed by at least three independent PC members or external reviewers. The DEXA proceedings quite clearly re?ect the current trends in the da- base area and we are happy with the balanced content of both the conference and the proceedings.
