Data base management system analysis and performance testing with respect to NASA requirements

Several candidate Data Base Management Systems (DBM's) that could support the NASA End-to-End Data System's Integrated Data Base Management System (IDBMS) Project, later rescoped and renamed the Packet Management System (PMS) were evaluated. The candidate DBMS systems which had to run on the Digital Equipment Corporation VAX 11/780 computer system were ORACLE, SEED and RIM. Oracle and RIM are both based on the relational data base model while SEED employs a CODASYL network approach. A single data base application which managed stratospheric temperature profiles was studied. The primary reasons for using this application were an insufficient volume of available PMS-like data, a mandate to use actual rather than simulated data, and the abundance of available temperature profile data

Database Principles and Technologies – Based on Huawei GaussDB

This open access book contains eight chapters that deal with database technologies, including the development history of database, database fundamentals, introduction to SQL syntax, classification of SQL syntax, database security fundamentals, database development environment, database design fundamentals, and the application of Huawei’s cloud database product GaussDB database. This book can be used as a textbook for database courses in colleges and universities, and is also suitable as a reference book for the HCIA-GaussDB V1.5 certification examination. The Huawei GaussDB (for MySQL) used in the book is a Huawei cloud-based high-performance, highly applicable relational database that fully supports the syntax and functionality of the open source database MySQL. All the experiments in this book can be run on this database platform. As the world’s leading provider of ICT (information and communication technology) infrastructure and smart terminals, Huawei’s products range from digital data communication, cyber security, wireless technology, data storage, cloud computing, and smart computing to artificial intelligence

Beyond Tragedy: Structure and Experience in Shakespeare\u27s Romances

In this compact, yet comprehensive exploration of Shakespeare\u27s romances, Robert W. Uphaus suggests that the romances bring us to a realm of human and dramatic experience that is beyond tragedy. The inexorable movement of tragedy toward death and a final close is absorbed in romance by a further movement in which death can lead to renewed life, characters can experience a second time of joy and peace, and the audience\u27s conventional expectations about reality and literature are challenged and enlarged. In the late tragedies of King Lear and Antony and Cleopatra, Uphaus finds the tragic structure augmented by elements that will later contribute to the form of the romances. Turning then to the romances themselves, he sees these plays as forming a profession in which Pericles is a brilliant outline of the conventions of romance and Cymbeline is romance taken to its dramatic limits, in fact to the point of parody. Through his fresh and provocative readings of the plays we experience anew the delight of Shakespearean romance and glimpse the world of renewal at its heart. Robert W. Uphaus is professor of English at Michigan State University. He is also the author of The Impossible Observer: Reason and the Reader in Eighteenth-Century Prose.https://uknowledge.uky.edu/upk_english_language_and_literature_british_isles/1055/thumbnail.jp

Sixth Goddard Conference on Mass Storage Systems and Technologies Held in Cooperation with the Fifteenth IEEE Symposium on Mass Storage Systems

This document contains copies of those technical papers received in time for publication prior to the Sixth Goddard Conference on Mass Storage Systems and Technologies which is being held in cooperation with the Fifteenth IEEE Symposium on Mass Storage Systems at the University of Maryland-University College Inn and Conference Center March 23-26, 1998. As one of an ongoing series, this Conference continues to provide a forum for discussion of issues relevant to the management of large volumes of data. The Conference encourages all interested organizations to discuss long term mass storage requirements and experiences in fielding solutions. Emphasis is on current and future practical solutions addressing issues in data management, storage systems and media, data acquisition, long term retention of data, and data distribution. This year's discussion topics include architecture, tape optimization, new technology, performance, standards, site reports, vendor solutions. Tutorials will be available on shared file systems, file system backups, data mining, and the dynamics of obsolescence

Problems of evaluation with special reference to the evaluation of Open University counselling

The thesis is concerned with problems of evaluation, both in the general sense of how anything may be evaluated and more specifically with the topic of the evaluation of the Open University counselling service. Although evaluation has long been a topic of concern to philosophers, the specialism of educational evaluation has emerged relatively recently. In particular, a body of ’theory' and practice has developed in the United States, oriented initially to the evaluation of curricula and increasingly towards the servicing of educational decisions of all kinds. A number of schemes for the conduct of evaluation have been proposed, yet there is widespread dissatisfaction with the results of evaluative research. Given the problematic nature of evaluation in education, and that an examination of the concept of evaluation, might throw some light on the difficulties, it is necessary to consider some of the philosophical positions on the subject. Following this a model of evaluation is outlined, and the importance of standards for the process of evaluation is emphasised. It is argued that calls for formal evaluations typically arise under conditions of dispute among decision-makers, and some possible ways of resolving such disputes are considered. The need to establish the decision-makers' degree of incorrigibility with regard to research findings is also proposed. An evaluation project on the Open University counselling service faced a number of difficulties, and the progress of this work is reported. The account provides a relatively rare glimpse of the social and organisational context of evaluative research in a highly unusual institution. The problems are considered in the light of the analysis of the evaluation process, and in terms of the specific circumstances surrounding the project. Finally, some suggestions are made as to how more fruitful evaluations might be achieved in the future

The contexts of use and the innovation of TV-centric network technologies: as viewers become consumer-users

This thesis seeks to explore something of the current nature of human, social and business contingencies constituting and motivating design, production, consumption and the use of technologies. It places a particular emphasis on the innovation of TV-centric network technologies - 'new' media technologies, particularly interactive television (i-Tv), intended to link, enhance or otherwise augment existing television technology and content. The empirical work in the thesis studied the development and implementation of a complex large-scale i-Tv trial in Cambridge, UK. Issues arising from the research led to the development of a general research framework - Contextual Usability (CU) - whose central aim is to draw awareness to the complex and multiple dimensions of the use process as a social and organisational construction, and also to redefine its place as an intrinsic experiential dimension in the domestication of products and services.Various senior managers and designers were interviewed within the company designing and producing the i-Tv technology and interface for the trial, as were 11 participant households. The author concludes with an overview suggesting the interconnected and interdependent nature of trials, technology, users, design, designers and organisation. For this he uses CU in relation to Molina's notion of Sociotechnical Constituencies to illustrate how social, cultural and organisational elements of trials both rely and impinge upon the implementation and interpretation of user and consumer research, and thus working 'images'of the user and the use process
