Reusing software improves quality as well as productivity. In practice, it is hard to achieve significant levels of reuse in commercial applications beyond generic support software. This tutorial will present programming and design techniques for achieving more reuse. The first session will examine the obstacles to reuse in commercial data processing, and illustrate the potential benefits. The main session will: 1) consider design reuse, source code reuse and routine libraries; 2) review the principles of modular design, cohesion, coupling and information hiding; 3) show how inheritance and dynamic binding extend and enhance these established techniques. The final session addresses organisational aspects of reuse, an alternative project lifecycle, metrics and developer motivation. The tutorial is intended for developers and their managers regardless of language, method or platform.","PeriodicalId":434404,"journal":{"name":"Proceedings Technology of Object-Oriented Languages and Systems.

Use cases considered harmful 被认为有害的用例

The UML 1.1 metamodel formally defined the \"uses\" and \"extend\" use case relationships as stereotypes of generalisation, yet both received interpretations that varied between inheritance and composition, reflecting a large degree of confusion among developers. The recently revised UML 1.3 has quietly dropped these in favour of new \"include\" and \"extend\" relationships, which are styled instead as kind of dependency. Despite this change, the deployment of use case diagrams encourages analysts to correspondence and develop models which conceal arbitrary jumps in the flow of control, corresponding to goto and come from statements, and in which unpleasant non-local dependencies exist across modules. A discussion of examples reveals how a conscientious designer must disassemble use case models completely to produce properly-structured code. A radical solution is proposed.","PeriodicalId":434404,"journal":{"name":"Proceedings Technology of Object-Oriented Languages and Systems. TOOLS 29 (Cat.

Very high level programming with collection components 使用集合组件进行非常高级的编程

This results both from weaknesses in the structure of the frameworks and from the poor degree of integration of collections into the languages. We present a new approach to the integration of collections in object-oriented languages in which collection types are part of the language but collection implementations are not. We also show how the integration of collection types allows automatic conversions which, among other advantages, provide a new solution to the problem of statically type-safe compatibility for collections.","PeriodicalId":434404,"journal":{"name":"Proceedings Technology of Object-Oriented Languages and Systems.

C++ is a programming language that supports multiple paradigms: classes, overloaded functions, templates, modules, procedural programming and more. Despite the language¿s flexibility and richness, however, there has previously been little effort to create a design method to support multiple paradigms within a single application. This tutorial explores a coherent framework for multi-paradigm design, offering an advanced set of design practices that form the foundation for a formal multi-paradigm design method. Attendees will gain an understanding of domain engineering methods that support multi-paradigm design. The presentation reveals how to analyze the application domain using principles of commonality and variation to define subdomains according to the most appropriate paradigm for each. The course explores deep questions of design to address fundamental issues of software abstraction.","PeriodicalId":434404,"journal":{"name":"Proceedings Technology of Object-Oriented Languages and Systems.

The developed information system has the network management responsibility and it offers a complete set of utilities to the network operator to facilitate its work. It has been necessary to balance requirements from the management point of view (real time interaction, statistics, etc.), requirements from the technical connection with the network (different technologies, buffering problems, etc.), and extra requirements imposed by the client (remote management option, easy to platform migration, etc.). Representation techniques based on object meta knowledge have been used as a powerful tool to provide a flexible and easy to extend mechanism to cover application design and implementation phases. The adopted architecture and the main components and their orchestration are described.

It was created by a consortium of organizations and since its publication in January 1995, it has proved to be extremely effective in delivering maintainable systems which match the needs of the business better than those produced using traditional life cycles.

Many framework design patterns have been documented, e.g. reverse engineering framework architectures from conventionally built applications for a given domain. The framework development cycle generally evolves from an open framework to a closed application. We describe a more flexible component-based approach to framework design that stresses a common interface for 'plugging-in' new components at different lifecycle stages. An analysis of framework-related user roles shows that the classical developer/end-user boundary is too rigid. We see the framework's development as a continuum within which its 'actors' can customise its behavior. This both increases the system's flexibility and reduces its maintenance requirement. A case study of three frameworks for different application domains illustrates the presented principles.","PeriodicalId":434404,"journal":{"name":"Proceedings Technology of Object-Oriented Languages and Systems.

To a large extent, the Internet server models currently deployed fail in this respect. The focus of this work is to alleviate some problems related to resource management in server environments. In particular, we propose a structured approach to binding threads (execution entities) to resource accounts (abstractions encapsulating rights to using particular amounts of particular resources). The approach advocates separation between protection domains (processes) and resource management; we argue that this is more appropriate for server systems than traditional approaches. Resource accounts address some issues related to trust and to dividing complex requests into separate sub-requests.","PeriodicalId":434404,"journal":{"name":"Proceedings Technology of Object-Oriented Languages and Systems.
