This book is aimed at students who need to learn the basics of programming or who are studying computing. It is a "hands on" book containing many examples which start by illustrating basic Oberon-2 language features and gradually increase in scope to cover object-oriented programming concepts and constructs. Oberon-2 is a successor to the language Pascal, which was also designed by Prof. N. Wirth [Wir71J. It has quickly become a major language used for teaching purposes. The only thing you need for successfully working through the book is to have access to a computer running Windows 3. 11 or Windows 95. The material in the book is useful to students of schools, colleges, and universities for teaching Oberon-2 and programming at an introductory level. of the book is not focused on software engineering or object The scope oriented technology; other books mentioned in the reference section already cover these topics in much greater depth. However, the examples in the book have been designed with these topics firmly in mind. Currently the term "object-oriented" is very much in fashion, having taken over from structured programming of the 1970s and '80s. In this book we have taken the view that a structured programming approach can be used to teach the fundamentals of programming algorithms. The object-oriented approach is then brought in as a complementary way to think, analyze, design and program.

Programming in Dylan is aimed at programmers who are already familiar with languages such as Pascal or C but who, as yet, have no knowledge of object-oriented languages. The author takes the reader through the development of Dylan by Apple and introduces the concept of object oriented languages, comparing Dylan to other languages such as CLOS, Smalltalk and C++. The author looks at fundamental concepts of the Dylan language before moving on to present the basic types (Boolean, vectors, strings etc.). Variables, expressions and assignment, and functions (both named and anonymous) are covered in detail. The Dylan class is introduced in its simple form and generic functions and library classes are discussed in depth. The author shows how modularisation needs to be used if large applications are to be developed and illustrates how to construct program libraries. A simulation and modelling example runs through the book.

This book contains a refereed collection of revised papers selected from the presentations at the France-Japan Workshop on Object-Based Parallel and Distributed Computation, OBPDC'95, held in Tokyo in June 1995.
The 18 full papers included in the book constitute a representative, well-balanced set of timely research contributions to the growing field of object-based concurrent computing. The volume is organized in sections on massively parallel programming languages, distributed programming languages, formalisms, distributed operating systems, dependable distributed computing, and software management.

Over the past 10 years, object technology has gained widespread acceptance within the software industry. Within a wider context, however, it has made little impact on the core applications which support businesses in carrying out their tasks. This volume contains a collection of papers establishing the need for Business Objects, with particular reference to work undertaken by the Object Management Group (OMG). The emphasis is on defining an agenda for establishing Business Object standards and architectures, for developing software technology to support Business Objects applications and managing object oriented development projects. The wide variety of papers presented, and their authors' expertise, make this book a significant contribution to the development of Business Objects and their management.

Delphi is a new Windows software development environment from Borland. Released in 1995, it has quickly built up an excellent reputation as one of the best Windows software development tools.
John Cowell shows how to program in Delphi using various tools. He provides lots of examples and illustrations and describes various database specific tools included with the Delphi package. The book shows how to use the Borland database engine along with other database formats (including Microsoft's Access). There are a number of chapters which cover the object-oriented aspects of Pascal, and advanced programming techniques such as drag-and-drop, DDE, OLE, and the creation of on-line help systems are also looked at. New users, as well as current Visual Basic users wanting to get up to speed on Delphi, will find this clear and informative book provides all the information they need to develop Windows applications quickly, competently, and easily.

This book addresses issues concerning the engineering of system prod ucts that make use of computing technology. These systems may be prod ucts in their own right, for example a computer, or they may be the computerised control systems inside larger products, such as factory automation systems, transportation systems and vehicles, and personal appliances such as portable telephones. In using the term engineering the authors have in mind a development process that operates in an integrated sequence of steps, employing defined techniques that have some scientific basis. Furthermore we expect the operation of the stages to be subject to controls and standards that result in a product fit for its intended purpose, both in the hands of its users and as a business venture. Thus the process must take account of a wide range of requirements relating to function, cost, size, reliabili ty and so on. It is more difficult to define the meaning of computing technology. These days this involves much more than computers and software. For example, many tasks that might be performed by software running in a general purpose computer can also be performed directly by the basic technology used to construct a computer, namely digital hardware. However, hardware need not always be digital; we live in an analogue world, hence analogue signals appear on the boundaries of our systems and it can sometimes be advantageous to allow them to penetrate further."

This book constitutes the refereed proceedings of the Second International Symposium on Object Technologies for Advanced Software, ISOTAS'96, held in Ishikawa, Japan, in March 1996. ISOTAS'96 was sponsored by renowned Japanese and international professional organisations.

Formal Object-Oriented Development provides a comprehensive overview of the use of formal object-oriented methods; it covers how and where they should be introduced into the development process, how they can be introduced selectively for critical parts of an application, and how to incorporate them effectively into existing deveopmental practices.
The text is extensively illustrated, both with tutorial and self-assessment excercises and with examples of industrial applications from the reactive systems domain. This book will be of interest to academic and industrial researchers, software engineering practitioners and consultants, and will also provide invaluable reading material for students learning Z++ and VDM++.

This book constitutes the refereed proceedings of the 10th European Conference on Object-Oriented Programming, ECOOP '96, held in Linz, Austria, in July 1996.
The 21 full papers included in revised version were selected from a total of 173 submissions, based on technical quality and originality criteria. The papers reflect the most advanced issues in the field of object-oriented programming and cover a wide range of current topics, including applications, programming languages, implementation, specification, distribution, databases, and design.

Without a doubt the idea of object-oriented programming has brought some motion into the field of programming methodology and enlarged the set of programming languages. Object-oriented programming is nothing new-it first arose in the sixties. The motivation came from the simulation of discrete event systems. The concept first manifested itself in the language Simula 67. It took nearly two decades for the method to gain impetus, and today object-oriented programming is an important concept and a powerful technique. Meanwhile, we can even speak of an over reaction, for the concept has become a buzzword. But buzzwords always appear where there is the hope of exploiting ill-informed clients because they see the new approach as the solution to all their problems. Thus object-oriented programming is often hailed as a panacea. And so the question is justified: What is really behind it? To let the cat out of the bag: There is more to object-oriented programming than merely putting data as objects in the fore ground, instead of algorithms to which the data are subject. It is more than purely an alternative view of programmed systems. To identify the essence of object-oriented programming, is the subject of this book. This is a textbook that shows in a didactically skillful way which concepts and constructs are new, where they can be employed reasonably, and what advantages they offer. For, not all programs are automatically improved by merely recasting them in an object-oriented style."

This volume presents carefully refereed versions of the best papers presented at the Workshop on Models and Languages for Coordination of Parallelism and Distribution, held during ECOOP '94 in Bologna, Italy in July 1994.
Recently a new class of models and languages for distributed and parallel programming has evolved; all these models share a few basic concepts: simple features for data description and a small number of mechanisms for coordinating the work of agents in a distributed setting. This volume demonstrates that integrating such features with those known from concurrent object-oriented programming is very promising with regard to language support for distribution and software composition.

This book presents an overview of two approaches to software engineering - formal methods and object-oriented techniques - and by extracting the best aspects of each demonstrates how better and safer software is being developed. Three main strands of research are identified and discussed: the application of formal techniques to object technology; the extension of formal methods with object-oriented concepts; and the formal foundations of object technology. Examples of each approach are included and areas such as concurrency and real time, which are especially important in the development of large scale, distributed and safety critical systems, are addressed. By focusing on these two, previously independent, techniques and illustrating how their merger is resulting in the development of tools which are essential to the development of large scale software the editors of this book have provided valuable coverage of this rapidly developing and important area.

This volume presents a comprehensive first course in the Monte Carlo method which will be suitable for graduate and undergraduate students in the mathematical sciences and engineering, principally operations research, statistics, mathematics, and computer science. The reader is assumed to have a sound understanding of calculus, introductory matrix analysis, probability, and intermediate statistics, but otherwise the book is self-contained. As well as a thorough exploration of the important concepts of the Monte Carlo method, the volume includes over 90 algorithms which allow the reader to move rapidly from the concepts to putting them into practice. The book also contains numerous exercises, many of them hands-on implementations of selected algoriths to demonstrate the application of these ideas in realistic settings. Software, freely available via ftp and portable across computing platforms, provides programs for pseudorandom number generation and statistical sample path data analysis. The software is suitable for use with the exercises as well as for more general applications. For professional mathematical scientists and engineers this book provides a ready reference to the Monte Carlo method, especially to implementable algoritzms for performing sampling experiments on a computer and for analyzing their results.

Conventional object-oriented data models are closed: although they allow users to define application-specific classes, they usually come with a fixed set of modelling primitives. This constitutes a major problem, as different application domains, e.g. database integration or multimedia, need special support.
Using an extended metaclass concept, this book provides for the solution of this problem a simple but extendible open object-oriented data model, a so-called RISC model. By introducing the basic concepts of the open object-oriented database management system VODAK, it demonstrates how the extended metaclass concept can be integrated homogeneously into object-oriented data models.

This volume presents the proceedings of the International Symposium on Object-Oriented Methodologies and Systems (ISOOMS '94), held in Palermo, Italy in September 1994 in conjunction with the AICA 1994 Italian Computer Conference.
The 25 full papers included cover not only technical areas of object-orientation, such as databases, programming languages, and methodological aspects, but also application areas. The book is organized in chapters on object-oriented databases, object-oriented analysis, behavior modeling, object-oriented programming languages, object-oriented information systems, and object-oriented systems development.

This volume contains papers from the OOPSLA-93 Conference Workshop on Security for Object-Oriented Systems, held in Washington DC, USA, on 26 September 1993. The workshop addressed the issue of how to introduce an acceptable level of security into object-oriented systems, as the use of such systems becomes increasingly widespread. The topic is approached from two different, but complementary, viewpoints: the incorporation of security into object-oriented systems, and the use of object-oriented design and modelling techniques for designing secure applications. The papers cover a variety of issues, relating to both mandatory and discretionary security, including security facilities of PCTE, information flow control, the design of multilevel secure data models, and secure database interoperation via role translation. The resulting volume provides a comprehensive overview of current work in this important area of research.

This volume contains papers from the Eighth Z User Meeting, to be held at the University of Cambridge from 29 - 30 June 1994. The papers cover a wide range of issues associated with Z and formal methods, with particular reference to practical application. These issues include education, standards, tool support, and interaction with other design paradigms such as consideration of real-time and object-oriented approaches to development. Among the actual topics covered are: the formal specification in Z of Defence Standard 00-56; formal specification of telephone features; specifying and interpreting class hierarchies in Z; and software quality assurance using the SAZ method. Z User Workshop, Cambridge 1994 provides an important overview of current research into industrial applications of Z, and will provide invaluable reading for researchers, postgraduate students and also potential industrial users of Z.

This volume contains the proceedings of the 8th European Conference on Object-Oriented Programming (ECCOP '94), held in Bologna, Italy in July 1994. ECOOP is the premier European event on object-oriented programming and technology. The 25 full refereed papers presented in the volume were selected from 161 submissions; they are grouped in sessions on class design, concurrency, patterns, declarative programming, implementation, specification, dispatching, and experience. Together with the keynote speech "Beyond Objects" by Luc Steels (Brussels) and the invited paper "Putting Objects to Work" by Norbert A. Streitz (GMD-IPSI, Darmstadt) they offer an exciting perspective on object-oriented programming research and applications.

This volume contains the papers presented at the Intemational Conference on Object Oriented Information Systems 00lS'94, held at South Bank University, London, December 19 - 21, 1994. In response to our call for papers, a total 85 papers from 24 different countries were submitted. Each paper was evaluated by at least two Program Committee members and an additional reviewer. Together, we selected 41 papers for presentation at the conference and inclusion in the Proceedings. Also included are the keynote addresses by Peter Gray and Michael Jackson. The other submissions were recommended for presentation in the poster sessions. Peter Gray, our invited speaker, evaluates the problems of object-oriented systems and data independence by looking at how object oriented database applications are failing to perceive its benefits, and instead rely too much on encapsulation. He suggests alternative kinds of object storage to preserve data independence. The second invited speaker, Michael Jackson describes a way of solving problems, by focusing directly on the problems themselves, their components and structures and on the relationships between the problem and the solution method. He discusses a particular view of the role of object-orientation in software development.

Database management is attracting wide interest in both academic and industrial contexts. New application areas such as CAD/CAM, geographic information systems, and multimedia are emerging. The needs of these application areas are far more complex than those of conventional business applications. The purpose of this book is to bring together a set of current research issues that addresses a broad spectrum of topics related to database systems and applications. The book is divided into four parts: - object-oriented databases, - temporal/historical database systems, - query processing in database systems, - heterogeneity, interoperability, open system architectures, multimedia database systems.

Interest has grown rapidly over the past dozen years in the application of object-oriented programming and methods to the development of distributed, open systems. This volume presents the proceedings of a workshop intended to assess the current state of research in this field and to facilitate interaction between groups working on very different aspects of object-oriented distributed systems. The workshop was held as part of the 1993 European Conference on Object-Oriented Programming (ECOOP '93). Over fifty people submitted position papers and participated in the workshop, and almost half presented papers. The presented papers were carefully reviewed and revised after the workshop, and 14 papers were selected for this volume.

Software architecture is critical to the success of software development projects. Unfortunately, many projects are unsuccessful in their attempts to leverage architecture-based development, especially large-scale projects. Lost in a myriad of possible UML diagrams, project teams often resort to ineffective ad-hoc techniques.

The purpose of this book is to enable software architects, their managers, and other development team members to become more effective in directing the course of large-scale software development projects. Written by two experienced architects that have worked in the trenches on many projects, this book provides practical advice for all software teams about developing and capturing critical software architectural concerns.

Leveraging the recent IEEE standard on software architecture and using UML compatible with versions 1.4 and 2.0 this book describes a series of viewpoints for capturing the software architecture and related concerns. These viewpoints convey essential information to users, stakeholders and other members of the development team.

Large-Scale Software Architecture covers:

• a series of UML based viewpoints for capturing software architecture and related concerns

• useful techniques for development of software architectures

• the roles and responsibilities of the software architect and the architecture team

• traps and pitfalls of architecture development

• utilization of reusable and off-the-shelf software frameworks and components

It is now more than twenty-five years since object-oriented programming was "inve- ed" (actually, more than thirty years since work on Simula started), but, by all accounts, it would appear as if object-oriented technology has only been "discovered" in the past ten years! When the first European Conference on Object-Oriented Programming was held in Paris in 1987, I think it was generally assumed that Object-Oriented Progr- ming, like Structured Programming, would quickly enter the vernacular, and that a c- ference on the subject would rapidly become superfluous. On the contrary, the range and impact of object-oriented approaches and methods continues to expand, and, - spite the inevitable oversell and hype, object-oriented technology has reached a level of scientific maturity that few could have foreseen ten years ago. Object-oriented technology also cuts across scientific cultural boundaries like p- haps no other field of computer science, as object-oriented concepts can be applied to virtually all the other areas and affect virtually all aspects of the software life cycle. (So, in retrospect, emphasizing just Programming in the name of the conference was perhaps somewhat short-sighted, but at least the acronym is pronounceable and easy to rem- ber!) This year's ECOOP attracted 146 submissions from around the world - making the selection process even tougher than usual. The selected papers range in topic from programming language and database issues to analysis and design and reuse, and from experience reports to theoretical contributions.
