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.

The NCITS Accredited Standards Committee H7 Object Information Management, now part of NCITS T3 Open Distributed Processing, and the Object Management Group BUsiness Object Domain Task Force (BODTF) jointly sponsored the Fifth Annual OOPSLA Workshop on Business Object Component Design and Implementation. The focus of the workshop was on design and implementation of business object component frameworks and architectures. Key aspects discussed included: • What is a comprehensive definition of a business object component'? • Are the four layers (user, workspace, enterprise, resource) presented at the OOPSLA'98 workshop the right way to layer a..bysiness object component. system? • How is a business object component implemented across these layers? What are the associated artefacts? Are there different object models representing the same business object component in different layers? • What are the dependencies between business object components? How can they be plug and play given these dependencies? How can they be flexible and adaptive? How do they participate in workflow systems? • How will the em~rgence of a web-based distributed object-computing infrastructure based on XML, influence business object component architectures? In particular, is the W3C WebBroker proposal appropriate for distributed business object component computing? The aim of the workshop was to: • Enhance the pattern literature on the specification, design, and implementation of interoperable, plug and play, distributed business object components.

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.

The annual colloquium on information retrieval research provides an opportunity for both new and established researchers to present papers describing work in progress or ?nal results. This colloquium was established by the BCS IRSG(B- tish Computer Society Information Retrieval Specialist Group), and named the Annual Colloquium on Information Retrieval Research. Recently, the location of the colloquium has alternated between the United Kingdom and continental Europe. To re?ect the growing European orientation of the event, the colloquium was renamed “European Annual Colloquium on Information Retrieval Research” from 2001. Since the inception of the colloquium in 1979 the event has been hosted in the city of Glasgow on four separate occasions. However, this was the ?rst time that the organization of the colloquium had been jointly undertaken by three separate computer and information science departments; an indication of the collaborative nature and diversity of IR research within the universities of the West of Scotland. The organizers of ECIR 2002 saw a sharp increase in the number of go- quality submissions in answer to the call for papers over previous years and as such 52 submitted papers were each allocated 3 members of the program committee for double blind review of the manuscripts. A total of 23 papers were eventually selected for oral presentation at the colloquium in Glasgow which gave an acceptance rate of less than 45% and ensured a very high standard of the papers presented.

Object-Oriented Design with Applications has long been the essential reference to object-oriented technology, which, in turn, has evolved to join the mainstream of industrial-strength software development. In this third edition--the first revision in 13 years--readers can learn to apply object-oriented methods using new paradigms such as Java, the Unified Modeling Language (UML) 2.0, and .NET. The authors draw upon their rich and varied experience to offer improved methods for object development and numerous examples that tackle the complex problems faced by software engineers, including systems architecture, data acquisition, cryptoanalysis, control systems, and Web development. They illustrate essential concepts, explain the method, and show successful applications in a variety of fields. You'll also find pragmatic advice on a host of issues, including classification, implementation strategies, and cost-effective project management. New to this new edition are An introduction to the new UML 2.0, from the notation's most fundamental and advanced elements with an emphasis on key changes New domains and contexts A greatly enhanced focus on modeling--as eagerly requested by readers--with five chapters that each delve into one phase of the overall development lifecycle. Fresh approaches to reasoning about complex systems An examination of the conceptual foundation of the widely misunderstood fundamental elements of the object model, such as abstraction, encapsulation, modularity, and hierarchy How to allocate the resources of a team of developers and mange the risks associated with developing complex software systems An appendix on object-oriented programming languages This is the seminal text for anyone who wishes to use object-oriented technology to manage the complexity inherent in many kinds of systems.

The Unified Modeling Language™ (UML®) is inherently object-oriented modeling language and was designed for use in object-oriented software applications. The applications could be based on the object-oriented technologies recommended by the Object Management Group (OMG), which owns the UML. The initial versions of UML (UML 1.x) were based on three leading object-oriented methods - Booch, OMT, and OOSE, to represent "the culmination of best practices in practical object-oriented modeling". UML 2.x is still object-oriented in its core (though there were some apparently unsuccessful attempts to extend UML to support other development methods). This book provides practical guidance on the modeling and design of object-oriented systems. Its specific goals are the following: ■ To provide a sound understanding of the fundamental concepts and historical evolution of the object model. ■ To facilitate a mastery of the notation and process of object-oriented modelling and design. ■ To teach the realistic application of object-oriented modelling and design within a variety of problem domains. The concepts presented all stand on a solid theoretical foundation, but this is primarily a pragmatic book that addresses the practical needs and concerns of software engineering practitioners, from the architect to the software developer.
