This volume constitutes the proceedings of the First International Symposiumorganized by the Japan Society for Software Science and Technology. The symposium was held in Kanazawa, Japan, November 4-6, 1993 and attracted many researchers from academia and industry as well as ambitioned practitioners. Object technologies, in particular object-oriented programming, object-oriented databases, and software object bases, currently attract much attention and hold a great promise of future research and development in diverse areas of advanced software. The volume contains besides 6 invited presentations by renown researchers and 25 contributed papers carefully selected by an internationalprogram committee from a total of 92 submissions.

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. The 14 papers included in final full versions, together with the abstracts of four invited papers, were carefully reviewed and selected from a total of 56 submissions; they address most current topics in object software technology, object-oriented programming, object-oriented databases, etc. The volume is organized in sections on design and evolution, parallelism and distribution, meta and reflection, and evolution of reuse.

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.

This book constitutes the thoroughly refereed post-proceedings of the 5th International Workshop on Software Composition, SC 2006, a satellite event of the European Joint Conferences on Theory and Practice of Software, ETAPS 2006. The book presents 21 revised full papers reflecting current research in software composition to foster development of composition models and techniques by using aspect-oriented programming, specification of component contracts and protocols, and methods of correct components composition.

As the application of object technology--particularly the Java programming language--has become commonplace, a new problem has emerged to confront the software development community. Significant numbers of poorly designed programs have been created by less-experienced developers, resulting in applications that are inefficient and hard to maintain and extend. Increasingly, software system professionals are discovering just how difficult it is to work with these inherited, "non-optimal" applications. For several years, expert-level object programmers have employed a growing collection of techniques to improve the structural integrity and performance of such existing software programs. Referred to as "refactoring," these practices have remained in the domain of experts because no attempt has been made to transcribe the lore into a form that all developers could use. . .until now. In Refactoring: Improving the Design of Existing Code, renowned object technology mentor Martin Fowler breaks new ground, demystifying these master practices and demonstrating how software practitioners can realize the significant benefits of this new process. With proper training a skilled system designer can take a bad design and rework it into well-designed, robust code. In this book, Martin Fowler shows you where opportunities for refactoring typically can be found, and how to go about reworking a bad design into a good one. Each refactoring step is simple--seemingly too simple to be worth doing. Refactoring may involve moving a field from one class to another, or pulling some code out of a method to turn it into its own method, or even pushing some code up or down a hierarchy. While these individual steps may seem elementary, the cumulative effect of such small changes can radically improve the design. Refactoring is a proven way to prevent software decay. In addition to discussing the various techniques of refactoring, the author provides a detailed catalog of more than seventy proven refactorings with helpful pointers that teach you when to apply them; step-by-step instructions for applying each refactoring; and an example illustrating how the refactoring works. The illustrative examples are written in Java, but the ideas are applicable to any object-oriented programming language.

This book constitutes the refereed proceedings of the 12th European Conference on Object-Oriented Programming, ECOOP'98, held in Brussels, Belgium, in July 1998. The book presents 24 revised full technical papers selected for inclusion from a total of 124 submissions; also presented are two invited papers. The papers are organized in topical sections on modelling ideas and experiences; design patterns and frameworks; language problems and solutions; distributed memory systems; reuse, adaption and hardware support; reflection; extensible objects and types; and mixins, inheritance and type analysis complexity.

The continual evolution of object oriented technologies creates both opportunities and challenges. However, despite the growing popularity of object oriented technology, there are numerous issues that have contributed to its inability to firmly entrench itself and take over for the older, proven technologies. Object oriented technology's image problem has created a highly difficult decision making process for corporations considering widespread adoption of these technologies. Object Oriented Technologies: Opportunities and Challenges addresses concerns, opportunities and technology trends in the application of object oriented technologies. The chapters of this book were selected to represent a variety of perspectives concerning the present and future of this broad sub-field of software development.
