Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a discussion of the application of data-flow machine concepts to the design and implementation of database machines which execute relational algebra queries. We analyze the performance of multiprocessor nested-loops and sort-merge join algorithms and show that the nested-loops algorithm is generally superior. Three levels of operand granularity for data-flow database machines are introduced and compared using the nested-loops join algorithm. We demonstrate that relation-level granularity is too coarse and that tuple-level granularity is too fine. The third level of granularity, a page of a relation, is shown to be the best choice from both hardware and software viewpoints. Finally a preliminary design for a data-flow database machine which utilizes page-level granularity and supports distributed control of instruction execution is presented. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains 24 papers presented at the Sixth International Workshop on Database Machines. The papers cover a wide spectrum of topics including: system architectures, storage structures, associative memory architectures, memory resident systems, deduction and retrospectives on maturing projects. The nature of the papers is highly technical and presumes knowledge of database management systems and familiarity with database machines. The book is representative of the dual trend in the field towards (1) search for new functionability and (2) attention to detail, completeness and performance of prototype implementations.

Available in PDF, EPUB and Kindle. Book excerpt: The International Workshop on Database Machines in Munich is the third of its kind, preceeded by the meetings in Florence (Sept. 81) and San Diego (Sept. 82). The workshop is aimed at providing an interchange of ideas and experience on computer systems designed to perform database operations more efficiently than general purpose computers with a software database management system. Many proposals have been published during the past 10 years, but now several systems have been built and practically implemented and some are even commercially available, so that confrontation with the real world is starting to occur. The kinds of question which arise during this phase of coming to maturity are those involved with evaluation and measurement. The emphasis of the workshop is therefore on performance evaluation and the respective modelling techniques and methodology. Data flow and other new topics (including algorithms) are also treated with respect to performance and efficiency. We are glad to be able to include some papers on existing commercial products - from both the designer and the user viewpoints. We hope to encourage critical comments in this field and have arranged a session with the title "Where Database Machines Are Going" - to be followed by a panel dis~ussion.

This book was released on 2012-12-06 with total page 693 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the Fifth International Workshop on Database Machines. The papers cover a wide spectrum of topics on Database Machines and Knowledge Base Machines. Reports of major projects, ECRC, MCC, and ICOT are included. Topics on DBM cover new database machine architectures based on vector processing and hypercube parallel processing, VLSI oriented architecture, filter processor, sorting machine, concurrency control mechanism for DBM, main memory database, interconnection network for DBM, and performance evaluation. In this workshop much more attention was given to knowledge base management as compared to the previous four workshops. Many papers discuss deductive database processing. Architectures for semantic network, prolog, and production system were also proposed. We would like to express our deep thanks to all those who contributed to the success of the workshop. We would also like to express our apprecia tion for the valuable suggestions given to us by Prof. D. K. Hsiao, Prof. D.

Download or read book Information Structure Design for Databases written by Andrew J. Mortimer and published by Butterworth-Heinemann. This book was released on 2014-05-12 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer Weekly Professional Series: Information Structure Design for Databases: A Practical Guide to Data modeling focuses on practical data modeling covering business and information systems. The publication first offers information on data and information, business analysis, and entity relationship model basics. Discussions cover degree of relationship symbols, relationship rules, membership markers, types of information systems, data driven systems, cost and value of information, importance of data modeling, and quality of information. The book then takes a look at entity relationship modeling connections, one-to-one relationship, and entity relationship modeling advanced topics, including connection traps, resolving many-to-many relationships, four combinations of membership, and entity merging. The text examines logical data dictionary, data flow diagrams, entity life history, and developing database applications. Topics include data modeling during development, waterfall approach, iterative development, sequence, selection, illegal data flow linkages, conservation of data, second normal form rule, and denormalization. The book is a valuable reference for researchers interested in data modeling.
Download or read book A Proposed Architecture for a mixed flow Database Machine written by Ahmed S. Mohamed and published by . This book was released on 1984 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A considerable improvement in processing relational database queries has been shown to be possible using data-driven processing strategies. Moreover, the few implementation trials of data-flow database machines exhibit potential solutions to some of the problems of conventional control-flow database machines. The intention in this thesis is to follow the data-driven approach in a fashion that avoids the shortcomings of the two extremes: pure control-flow and pure data-flow. A special purpose multi-processor system, the 'mixed-flow' database machine, that lies in between strict control-flow and strict data-flow systems is described. It utilizes a resource pool of specialized functional processors and buffers to embody query trees directly as hardware structures (processor networks), and to execute those queries under a 'mixed-flow' query processing strategy using pipelining and parallel processing. The 'mixed-flow' query processing strategy introduces the notion of regulating data-flow query processing through planning the flow in advance and adaptively re allocating resources in the processor network at discrete time-slices. A transformation to a maximum-flow/minimum-cut problem allows planning input flows to different processors in the network and realizes the optimal degree of network pipelining (i.e. optimal given the estimated selectivity factors of the processors). Furthermore, the adaptive re-allocation of resources provides for secure future network operation (close to the optimal planned flow) in addition to resolving existing network bottlenecks. The 'mixed-flow' strategy is experimentally compared with the pure 'data-flow' strategy and is shown to improve performance with percentages around %25 under normal and heavy loads.
Download or read book Data Flow Computing written by John A. Sharp and published by Intellect (UK). This book was released on 1992 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an increasing interest in data flow programming techniques. This interest is motivated in part by the rapid advances in technology (and the need for distributed processing techniques), in part by a desire for faster throughput by applying parallel processing techniques, and in part by search for a programming tool that is closer to the problem solving methods that people naturally adopts rather than current programming languages. This book contains a selection of chapters by researchers on various aspects of the data flow approach in computing. Topics covered include: comparisons of various data flow machine designs, data flow architectures, intentional programming and operator nets, and the relationship between data flow models and modern structured design techniques, among others. The book also includes a brief introduction to the data flow approach, a bibliography, and reviews of where research into data flow might be heading.
