Supporting the object-oriented database on the Kernel Database System

If a single operating system can support multitudes of different programming languages and data structures, a database system can support a variety of data models and data languages. In this thesis, a Kernel Database System (KDS) supporting classical data models and data languages (i.e., hierarchical, network, relational, and functional) is used to support a demonstration object oriented data model and data language. This thesis extends previous research by accommodating an object-oriented-data-model-and-language interface in the KDS. Consequently, the research shows that it is feasible to use the KDS to support modem data models and languages as well as classical ones. This thesis details the KDS design, Insert operation, and Display function. This thesis also details how to implement modifications to the Test-Interface so that the KDS can support the object-oriented database. This thesis proves complex data structures in an object-oriented data model can be realized using an attribute-based data model which is the kernel data model of the KDS. Second, it details how the KDS is designed showing why no changes needed to be made to the KDS to implement the object-oriented toy database. Third, it argues the advantages of using a KDS in the database-system design. The KDS design produces savings in costs from compatability, reduced training, expandability, and software reuse.http://archive.org/details/supportingobject1094535152NANAU.S. Navy (U.S.N.) author.;Korean Army author

Data bases and data base systems related to NASA's Aerospace Program: A bibliography with indexes

This bibliography lists 641 reports, articles, and other documents introduced into the NASA scientific and technical information system during the period January 1, 1981 through June 30, 1982. The directory was compiled to assist in the location of numerical and factual data bases and data base handling and management systems

Building real-time audio applications with component technology

The thesis looks at how QoS-aware applications (QSAs), with an Internet phone as a case, can be built from components (with Enterprise Java Beans (EJB) as the chosen component model). It also identifies limitations of the EJB standard that cause problems implementing real-time audio applications. The requirements to the EJB platform are identified by analyzing a generic design which is made from common components. These components are found by inspecting existing applications and communication architectures. Three Internet phone applications (with and without EJB) are made for performance measurements, and as a help to the analysis work. Finally in this thesis, a list of suggested extensions/changes to the EJB standard that can eliminate the identified limitations, is presente

Technologies to maintain biological diversity

The principal aim of this report is to identify and assess the technological and institutional opportunities and constraints to maintaining biological diversity in the United States and worldwide

An Introduction to Database Systems

This textbook introduces the basic concepts of database systems. These concepts are presented through numerous examples in modeling and design. The material in this book is geared to an introductory course in database systems offered at the junior or senior level of Computer Science. It could also be used in a first year graduate course in database systems, focusing on a selection of the advanced topics in the latter chapters

Object technology: A white paper

Object-Oriented Technology (OOT), although not a new paradigm, has recently been prominently featured in the trade press and even general business publications. Indeed, the promises of object technology are alluring: the ability to handle complex design and engineering information through the full manufacturing production life cycle or to manipulate multimedia information, and the ability to improve programmer productivity in creating and maintaining high quality software. Groups at a number of the DOE facilities have been exploring the use of object technology for engineering, business, and other applications. In this white paper, the technology is explored thoroughly and compared with previous means of developing software and storing databases of information. Several specific projects within the DOE Complex are described, and the state of the commercial marketplace is indicated

Greening Europe

The third installment of the ‘European Public Investment Outlook’ series is an important and timely publication that draws together recent analyses to recommend significant increases in public investment in green ventures. Compelling data from key economists affiliated with international organizations like the International Monetary Fund, European Investment Bank and the European Commission, as well as academic departments and policy institutes are a clarion call for green investment to boost the economy and put the planet on a sustainable path. Like its predecessors, the book presents the issues in a lucid and navigable manner. Part I explores the EU’s current levels of green public investment, as well as the challenges ahead in achieving net zero carbon emissions after years of decreasing funding and the obstacles presented by the COVID-19 pandemic and the Russian invasion of Ukraine. The public investment trends of France, Germany, Italy and Spain are systematically evaluated, as well as the REPowerEU policy – accelerated in Spring 2022 – to move away from Russia’s supply of fossil fuels. Part II focuses on the investment needed for green transition; the important economic and fiscal effects and benefits this would bring; and the reality of what is required before 2030 to achieve the EU’s carbon-neutral targets by 2050. Greening Europe is essential reading for economists, environmentalists, and policymakers. It should also be of interest to anyone who wants to understand the cost implications of the ‘carbon-neutral’ policies that governments have promised, and the urgent need to change our approach towards energy usage
