Advanced Database Indexing begins by introducing basic material on storage media, including magnetic disks, RAID systems and tertiary storage such as optical disk and tapes. Typical access methods (e.g. B+ trees, dynamic hash files and secondary key retrieval) are also introduced. The remainder of the book discusses recent advances in indexing and access methods for particular database applications. More specifically, issues such as external sorting, file structures for intervals, temporal access methods, spatial and spatio-temporal indexing, image and multimedia indexing, perfect external hashing methods, parallel access methods, concurrency issues in indexing and parallel external sorting are presented for the first time in a single book. Advanced Database Indexing is an excellent reference for database professionals and may be used as a text for advanced courses on the topic.

This collection features the top papers from the 8th International Conference on Enterprise Information Systems (ICEIS 2006), held in Paphos, Cyprus. Organized by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) in collaboration with various universities, ICEIS serves as a vital platform for researchers, engineers, and practitioners focused on the business applications of information systems. The conference included five simultaneous tracks that explored diverse aspects of enterprise computing: “Databases and Information Systems Integration,” “Artificial Intelligence and Decision Support Systems,” “Information Systems Analysis and Specification,” “Software Agents and Internet Computing,” and “Human–Computer Interaction.” Each track emphasized practical applications, showcasing the advantages of Information Systems and Technology for various industries, thereby bridging the gap between academia and enterprise. Following the previous year's success, ICEIS 2006 attracted 404 paper submissions from over 40 countries worldwide. Ultimately, 63 full papers were published and presented, alongside 102 work-in-progress or position papers for short presentations and another 75 for poster presentations.

This book constitutes the thoroughly refereed post-proceedings of the 8th Panhellenic Conference on Informatics, PCI 2001, held in Nicosia, Cyprus in November 2001. The 31 revised full papers presented were carefully selected and improved during two months of reviewing from 104 conference papers. The papers cover the areas of databases, data mining and intelligent systems, e-learning, human computer interaction, image processing, networks and systems, software and languages, and theoretical computer science.

This collection of invited papers explores various advancements in data management and database technologies. It discusses transforming networks into databases, personalizing data management, and scalable similarity searches. The integration of XML databases with the Semantic Web is examined, along with an XML algebra for XQuery and the refinement of XPath queries based on XML schema definitions. Notable topics include X-Warehousing for complex data and semantic querying across distributed data sources. The maintenance and creation of materialized views are addressed, focusing on multi-source views and clustering-based selection methods. Database modeling techniques are presented, including relationship design through spreadsheet reasoning and context-aware preferences. The implementation of a deductive object-oriented database system is also highlighted. In the realm of web information systems, strategies for optimizing hidden web access and middleware approaches to database caching are discussed. The papers delve into query processing and indexing techniques, such as efficient processing of SAPE queries, new indexing methods for continuous time sequences, and multi-nearest neighbor query processing in spatial databases. Data mining and clustering topics include automatic density-based clustering calculations and symbolic music genre classification. The collection concludes with discussions on merging and querying inconsis
