基于构件的软件复用和开发被认为是提高软件开发效率和质量的有效途径,并在分布式系统中得到了广泛的应用.但是,目前的软件构件技术主要还是着眼于构件实现模型和运行时互操作,缺乏一套系统的方法以指导整个开发过程.近年来,以构件为基本单元的软件体系结构研究取得了较大的发展.它通过对软件系统整体结构和特性的描述,为面向构件的软件开发提供了一个自顶向下的途径.介绍了一种以软件体系结构为指导,面向构件的软件开发方法,试图为基于构件的软件复用提供一种有效的解决方案.这种方法主要是将软件体系结构引入到软件开发的各个阶段,作为系统开发的蓝图,利用工具支持的自动转换机制缩小从高层设计到实现的距离,而后在构件平台的运行支持下实现自动的系统组装生成. 相似文献

软件复用是在软件开发过程中避免重复劳动的解决方案,但要设计在许多领域都通用的可复用业务组件是很困难的,而面向领域的复用是在一个特定应用领域中实现复用;因此,设计大粒度复用的应用框架对于提高软件的生产率和软件质量具有重要的意义;文中以软件复用为出发点,基于构件化软件的开发思路,对软件的构件技术、领域工程、面向领域的应用框架技术进行了深入的研究,提出了基于需求驱动的面向领域应用框架的开发方法,并详细说明了该方法在项目评审领域的应用. 相似文献

Over the past several decades, numerous software technologies have been developed for overcoming the software crisis. Among these technologies, reuse has been recognized as one of the most important software technologies. Recently, it has gained substantial attention as a possible solution to the software crisis in Ada and other software communities. The purpose of this empirical study is to examine how organizations actually exploit reuse technologies and evaluates how reuse factors affect the rate of reuse in an organization. This study is an attempt to enhance the measurement of the rate of reuse and the effectiveness of reuse by establishing conceptual foundations in the literature for reuse and conducting an empirical investigation of organizations using Ada technology. This study differentiated software reuse into six criteria: domain, human, tool, organization, software metrics, and environment. The results of this study show that the rate of reuse significantly depends upon reuse capability, software development effort, object-oriented design capability, repository development effort, Ada technology capability, and domain capability 相似文献

Information systems development is typically acknowledged as an expensive and lengthy process, often producing code that is of uneven quality and difficult to maintain. Software reuse has been advocated as a means of revolutionizing this process. The claimed benefits from software reuse are reduction in development cost and time, improvement in software quality, increase in programmer productivity, and improvement in maintainability. Software reuse entails undeniable costs of creating, populating, and maintaining a library of reusable components. There is anecdotal evidence to suggest that some organizations benefit from reuse. However, many software developers practicing reuse claim these benefits without formal demonstration thereof. There is little research to suggest when the benefits are expected and to what extent they will be realized. For example, does a larger library of reusable components lead to increased savings? What is the impact of component size on the effectiveness of reuse? This research seeks to address some of these questions. It represents the first step in a series wherein the effects of software reuse on overall development effort and costs are modeled with a view to understanding when it is most effective. 相似文献

一种基于PDCA的软件过程控制与改进模型 总被引:4,自引:0,他引:4
CMM/CMMI(capability maturity model/CMM integration)自1999年开始为中国软件企业所接受并逐步得以推广,但目前中国实施CMM/CMMI的企业还不多,有些企业实施效果并不理想.通过调查软件企业在实施CMM/CMMI过程中存在的问题,并对发现的问题及其负面影响进行分析,提出了基于PDCA(plan-do-check-action)的软件过程控制与改进模型,开发了SoftPM软件质量管理平台.该平台的广泛应用表明,该模型对提高CMM/CMMI的企业软件过程的效率和改善实施效果很有帮助. 相似文献

Software organizations can significantly improve the quality of their output if they have a defined and documented software process, together with the appropriate techniques and tools to measure its effectiveness. Without a defined process it is impossible to measure success or focus on how development capability can be enhanced. To date, a number of software process improvement frameworks have been developed and implemented. However, most of these models have been targeted at large-scale producers. Furthermore, they have applied to companies who use traditional development techniques. Smaller companies and those operating in development areas where speed of delivery is paramount have not, as yet, had process improvement paradigms available for adoption.This study examined the software process in a small company and emerged with the recommendation of the use of the Dynamic Systems Development Method (DSDM) and the Personal Software Process (PSP) for achieving software process improvement. 相似文献

一种个体软件过程能力度量方法 总被引:1,自引:0,他引:1
个体软件过程(PSP)是由卡内基×梅隆大学软件工程研究所的Humphrey领导开发的.它是一种可用于控制、管理和改进个人工作方式的自我持续改进过程.随着工业界对软件过程改进需求的日益增长,PSP成为了软件组织为达成完全(从宏观到微观)量化过程管理研究中的一个热点课题.软件过程研究表明,高水平的个体软件过程能力是软件项目成功的关键,如何进行有效的个体软件过程能力度量是PSP中的一个核心问题.现有方法不能同时有效处理个体软件过程能力度量中的可变规模收益、多变量输入/输出以及决策者偏好问题.提出了一种综合了数据包络分析(DEA)和层次分析法(AHP)的个体软件过程能力评价方法——PSPADA,介绍了PSPADA的个体软件过程能力评价模型和核心算法(集成决策者偏好和估计规模收益).实验结果显示,PSPADA能够在考虑决策者偏好的同时,有效地进行多指标、规模收益可变的量化评估. 相似文献

The author presents a high-level organizational paradigm for development and maintenance in which an organization can learn from development and maintenance tasks and then apply that paradigm to several maintenance process models. Associated with the paradigm is a mechanism for setting measurable goals, making it possible to evaluate the process and the product and learn from experience. He discusses three maintenance models: the quick-fix, the iterative-enhancement, and the full-reuse model. He establishes a framework for classifying reusable objects and selecting a model. He offers a scheme that categorizes three aspects of reuse: the reusable object, the reusable object's context, and the process of transforming that object. The author then discusses what he terms reuse enablers: an improvement paradigm that helps organizations evaluate, learn, and enhance their software processes and products; a reuse-oriented evolution environment that encourages and supports reuse; and automated support for the paradigm and environment as well as for measurement and evaluation 相似文献
