Object Management

First published in 1992, this volume explores the use of object oriented methods which is forecast to grow rapidly, with their flexibility and facility to overcome some of the inadequacies of relational databases. This timely book reviews their potential in the data management context. It examines the impact of object oriented techniques on the practice of data management including data analysis, database design, database administration and DBMS operation. The main emphasis of the book is on practical experience of developing and applying 00 methods in the most popular application areas. Its four parts covering the background to object technology, the products, the applications and the implications.

Distributed and Parallel Database Object Management brings together in one place important contributions and state-of-the-art research results in this rapidly advancing area of computer science. Distributed and Parallel Database Object Management serves as an excellent reference, providing insights into some of the most important issues in the field.

N etwork-based computing domain unifies all best research efforts presented from single computer systems to networked systems to render overwhelming computational power for several modern day applications. Although this power is expected to grow with respect to time due to tech nological advancements, application requirements impose a continuous thrust on network utilization and on the resources to deliver supreme quality of service. Strictly speaking, network-based computing dornain has no confined scope and each element offers considerable challenges. Any modern day networked application strongly thrives on efficient data storage and management system, which is essentially a Database System. There have been nurnber of books-to-date in this domain that discuss fundamental principles of designing a database systern. Research in this dornain is now far matured and rnany researchers are venturing in this dornain continuously due to a wide variety of challenges posed. In this book, our dornain of interest is in exposing the underlying key challenges in designing algorithms to handle unpredictable requests that arrive at a Distributed Database System(DDBS) and evaluating their performance. These requests are otherwise called as on-line requests arriving at a system to process. Transactions in an on-line Banking service, Airline Reservation systern, Video-on-Demand systern, etc, are few examples of on-line requests.

\My tailor is Object-Oriented". Most software systems that have been built - cently are claimed to be Object-Oriented. Even older software systems that are still in commercial use have been upgraded with some OO ?avors. The range of areas where OO can be viewed as a \must-have" feature seems to be as large as the number of elds in computer science. If we stick to one of the original views of OO, that is, to create cost-e ective software solutions through modeling ph- ical abstractions, the application of OO to any eld of computer science does indeed make sense. There are OO programming languages, OO operating s- tems, OO databases, OO speci cations, OO methodologies, etc. So what does a conference on Object-Oriented Programming really mean? I honestly don’t know. What I do know is that, since its creation in 1987, ECOOP has been attracting a large number of contributions, and ECOOP conferences have ended up with high-quality technical programs, featuring interesting mixtures of theory and practice. Among the 183 initial submissions to ECOOP’99, 20 papers were selected for inclusion in the technical program of the conference. Every paper was reviewed by three to ve referees. The selection of papers was carried out during a t- day program committee meeting at the Swiss Federal Institute of Technology in Lausanne. Papers were judged according to their originality, presentation qu- ity, and relevance to the conference topics.

ECOOP '91 is the fifth annual European Conference on Object-Oriented Programming. From their beginning, the ECOOP conferences have been very successful as a forum of high scientific quality where the newest devel- opments connected to object-oriented programming and related areas could be presented and discussed. Over the last few years object-oriented technology has gained widespread use and considerable popularity. In parallel with this, the field has matured scientifically, but there is still a lot of room for new ideas and for hot debates over fundamental issues, as these proceedings show. The 22 papers in this volume were selected by the programme committee from 129 submissions. Important issues discussed in the contributions are language design, specification, databases, concurrency types and software development.

Computer Science Workbench is a monograph series which will provide you with an in depth working knowledge of current developments in computer technology. Every volume in this series will deal with a topic of importance in computer science and elaborate on how you yourself can build systems related to the main theme. You will be able to develop a variety of systems, including computer software tools, computer graphics, computer animation, database management systems, and computer-aided design and manufacturing systems. Computer Science Workbench represents an important new contribution in the field of practical computer technology. Tosiyasu L. Kunii Preface The goal of this book is to give concrete answers to questions such as what object oriented databases are, why they are needed, how they are implemented, and how they are applied, by describing a research prototype object-oriented database system called Jasmine. That is, this book is aimed at creating a consistent view to object-oriented databases. The contents of this book are directly based on the results of the Jasmine project conducted at Fujitsu Laboratories, Ltd. The book is a polished version of my doctoral dissertation, which includes research papers which I have authored and published.

This proceedings contains some of the papers presented at the Business Object and Implementation Workshops held at OOPSLA'96, OOPSLA'97 and OOPSLA'98. The main theme of the workshops is to document the evolution of business objects, from ~any perspectives, including modelling, implementation, standards and applications. The 1996 workshop intended to clarify the specification, design, and implementation of interoperable, plug and play, distributed business object components and their suitability for delivery of enterprise applications; and to assess the impact of the WWW and, more specifically, the Intranet on the design and implementation of business object components. The main focus of the workshop was: What design patterns will allow implementation of business objects as plug and play components? How can these components be assembled into domain specific frameworks? What are the appropriate architectures/mechanisms as distributed object systems? What for implementing these frameworks organisational and development process issues need to be addressed to successfully deliver these systems? Is this approach an effective means for deploying enterprise application solutions? The third annual workshop (OOPSLA'97) was jointly sponsored by the Accredited Standards Committee X3H7 Object Information Management Technical Committee and the Object Management Group (OMG) Business Object Domain Task Force (BODTF) for the purpose of soliciting technical position papers relevant to the design and implementation of Business Object Systems.

This comprehensive collection is a survey of research in object-oriented databases, offering a substantive overview of the field, section introductions, and over 40 research papers presented in their original scope and detail. The balanced selection of articles presents a confluence of ideas from both the language and database research communities that have contributed to the object-oriented paradigm. The editors develop a general definition and model for object-oriented databases and relate significant research efforts to this framework. Further, the collection explores the fundamental notions behind object-oriented databases, semantic data models, implementation of object-oriented systems, transaction processing, interfaces, and related approaches. Research and theory are balanced by applications to CAD systems, programming environments, and office information systems.
