Book excerpt: Multidimensional arrays are one of the fundamental computing abstractions to represent data across virtually all areas of science and engineering, and beyond. Due to their ubiquity, multidimensional arrays have been studied extensively across many areas of computer science. This survey provides a comprehensive guide for past, present, and future research in array data management from a database perspective. Unlike previous surveys that are limited to raster processing in the context of scientific data, this survey considers all types of arrays: rasters, data cubes, and tensors. The author's goal is to identify and analyze the most important research ideas on arrays and to serve two objectives: first, to summarize the most relevant work on multidimensional array data management by identifying the major research problems; and second, to organize this material to provide an accurate perspective on the state-of-the-art and future directions in array processing.Multidimensional Array Data Management covers all data management aspects, from array algebras and query languages to storage strategies, execution techniques, and operator implementations. Moreover, the author discusses which research ideas are adopted in real systems and how are they integrated in complete data processing pipelines. Finally, the author compares arrays with the relational data model. The result is a thorough survey on array data management that is an excellent resource for anyone interested in this topic, independent of experience level.

Available in PDF, EPUB and Kindle. Book excerpt: th 2002 DEXA, the 13 International Conference on Database and Expert Systems Applications was held on September 2–6, 2002, at the Université Aix–Marseille II, France. The quickly growing field of information systems required the establishment of more specialized discussion platforms (the DaWaK conference, EC-Web conference, eGOV conference and DEXA workshops), and there were held in parallel with DEXA, also in Aix-en-Provence. The resulting book was prepared with great effort. Starting with the preparation of submitted papers, the papers went through the reviewing process. The accepted papers were revised to final versions by their authors and arranged to the conference program. This year 241 papers were submitted and our thanks go to all who have contributed. The program committee and the supporting reviewers produced altogether about 730 referee reports, on average three reports per paper, and selected 89 papers for presentation. The papers presented here encompass the extensive domain of databases; together with the other conferences and workshops of the DEXA event cluster a vast part of applied computer science was covered. In this way DEXA has blazed the trail. At this point we would like to acknowledge to all institutions which actively supported this conference and made it possible. These are: • IUT (Université Aix – Marseille II), • FAW, • DEXA Association, • the Austrian Computer Society, • and Microsoft Research

Download or read book Handbook of Data Intensive Computing written by Borko Furht and published by Springer Science & Business Media. This book was released on 2011-12-10 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data Intensive Computing refers to capturing, managing, analyzing, and understanding data at volumes and rates that push the frontiers of current technologies. The challenge of data intensive computing is to provide the hardware architectures and related software systems and techniques which are capable of transforming ultra-large data into valuable knowledge. Handbook of Data Intensive Computing is written by leading international experts in the field. Experts from academia, research laboratories and private industry address both theory and application. Data intensive computing demands a fundamentally different set of principles than mainstream computing. Data-intensive applications typically are well suited for large-scale parallelism over the data and also require an extremely high degree of fault-tolerance, reliability, and availability. Real-world examples are provided throughout the book. Handbook of Data Intensive Computing is designed as a reference for practitioners and researchers, including programmers, computer and system infrastructure designers, and developers. This book can also be beneficial for business managers, entrepreneurs, and investors.
Download or read book Multi versioned Data Storage and Iterative Processing in a Parallel Array Database Engine written by Emad Soroush and published by . This book was released on 2014 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists today are able to generate data at an unprecedented scale and rate. For example the Sloan Digital Sky Survey (SDSS) generates 200GB of data containing millions of objects on each night on its routine operation. The large hadron collider is producing even more data today which is approximately 30PB annually. The Large Synoptic Survey Telescope (LSST) also will be producing approximately 30TB of data per night in a few years. Also, in many fields of science, multidimensional arrays rather than flat tables are standard data types because data values are associated with coordinates in space and time. For example, images in astronomy are 2D arrays of pixel intensities. Climate and ocean models use arrays or meshes to describe 3D regions of the atmosphere and oceans. As a result, scientists need powerful tools to help them manage massive arrays. This thesis focuses on various challenges in building parallel array data management systems that facilitate massive-scale data analytics over arrays. The first challenge with building an array data processing system is simply how to store arrays on disk. The key question is how to partition arrays into smaller fragments called chunks that form the unit of IO, processing, and data distribution across machines in a cluster. We explore this question in ArrayStore, a new read-only storage manager for parallel array processing. In ArrayStore, we study the impact of different chunking strategies on query processing performance for a wide range of operations, including binary operators and user-defined functions. ArrayStore also proposes two new techniques that enable operators to access data from adjacent array fragments during parallel processing. The second challenge that we explore in building array systems is the ability to create, archive, and explore different versions of the array data. We address this question in TimeArr, a new append-only storage manager for an array database. Its key contribution is to efficiently store and retrieve versions of an entire array or some sub-array. To achieve high performance, TimeArr relies on several techniques including virtual tiles, bitmask compression of changes, variable-length delta representations, and skip links. The third challenge that we tackle in building parallel array engines is how to provide efficient iterative computation on multi-dimensional scientific arrays. We present the design, implementation, and evaluation of ArrayLoop, an extension of SciDB with native support for array iterations. In the context of ArrayLoop, we develop a model for iterative processing in a parallel array engine. We then present three optimizations to improve the performance of these types of computations: incremental processing, mini-iteration overlap processing, and multi-resolution processing. Finally, as motivation for our work and also to help push our technology back into the hands of science users, we have built the AscotDB system. AscotDB is a new, extensible data analysis system for the interactive analysis of data from astronomical surveys. AscotDB provides a compelling and powerful environment for the exploration, analysis, visualization, and sharing of large array datasets.
Download or read book Database and Expert Systems Applications written by Heinrich C. Mayr and published by Springer. This book was released on 2003-06-29 with total page 1010 pages. Available in PDF, EPUB and Kindle. Book excerpt: th DEXA 2001, the 12 International Conference on Database and Expert Systems Applications was held on September 3–5, 2001, at the Technical University of Munich, Germany. The rapidly growing spectrum of database applications has led to the establishment of more specialized discussion platforms (DaWaK conference, EC Web conference, and DEXA workshop), which were all held in parallel with the DEXA conference in Munich. In your hands are the results of much effort, beginning with the preparation of the submitted papers. The papers then passed through the reviewing process, and the accepted papers were revised to final versions by their authors and arranged with the conference program. All this culminated in the conference itself. A total of 175 papers were submitted to this conference, and I would like to thank all the authors. They are the real base of the conference. The program committee and the supporting reviewers produced altogether 497 referee reports, on average of 2.84 reports per paper, and selected 93 papers for presentation. Comparing the weight or more precisely the number of papers devoted to particular topics at several recent DEXA conferences, an increase can be recognized in the areas of XMS databases, active databases, and multi and hypermedia efforts. The space devoted to the more classical topics such as information retrieval, distribution and Web aspects, and transaction, indexing and query aspects has remained more or less unchanged. Some decrease is visible for object orientation.
