本体论与构件复用

软件复用主要有两种方式,一是产品复用,二是过程复用。构件的产品复用建立在接口不变的基础上。传统的建模方法关于对象之间联系的概念存在着模糊性,为构件接口设计和构件复用带来了隐患。该文将本体论引入构件设计,对构件对象的联系进行本体分析,目的在于为构件对象建立清晰、完整的本体模型,为设计遵守接口不变性原则和具有产品复用性的构件奠定基础;同时也在理论层次上探索本体模型向构件接口定义自动映射的机制,研究构件开发的过程复用。

超图模型:基于超图的设计模式描述和复用实现

设计模式描述了面向对象软件设计的经验,是软件复用的关键技术。由于设计模式涉及范围广泛而且抽象,即使模式本身并不深奥,因其表示或描述隐晦,在软件开发中难以理解和实现复用。文章提出了超图模型,即基于超图的设计模式表示,并对其在软件系统开发中的复用进行了分析研究。对基于设计模式的软件系统构建进行了探索。     

基于复用簇的测试用例复用度量

随着软件测试复用实践的深入、测试用例库规模的不断扩大,对测试用例复用的管理和评价的研究也逐渐引起人们的关注.在详细分析了测试用例复用行为的基础上,提出复用簇和测试用例从属度的概念,并基于复用簇和从属度建立测试用例复用度量模型.模型以复用为导向,建立和复用行为相关联的复用簇管理模式,并通过从属度为复用建立度量方法.该复用度量模型实现了计算过程的自动化,改进了简单计算测试用例复用次数的度量方法,保证复用度量的客观性和准确性,使复用度量的量化评价成为可能.

Building enterprise reuse program

Reuse is viewed as a realistically effective approach to solving software crisis. For an organization that wants to build a reuse program, technical and non-technical issues must be considered in parallel. In this paper, a model-based approach to building systematic reuse program is presented. Component-based reuse is currently a dominant approach to software reuse. In this approach, building the right reusable component model is the first important step. In order to achieve systematic reuse, a set of component models should be built from different perspectives. Each of these models will give a specific view of the components so as to satisfy different needs of different persons involved in the enterprise reuse program. There already exist some component models for reuse from technical perspectives. But less attention is paid to the reusable components from a non-technical view, especially from the view of process and management. In our approach, a reusable component model—FLP model for reusable component—is introduced. This model describes components from three dimensions (Form, Level, and Presentation) and views components and their relationships from the perspective of process and management. It determines the sphere of reusable components, the time points of reusing components in the development process, and the needed means to present components in terms of the abstraction level, logic granularity and presentation media. Being the basis on which the management and technical decisions are made, our model will be used as the kernel model to initialize and normalize a systematic enterprise reuse program.

A Component Model for Perspective Management of Enterprise Software Reuse

This paper discusses that in order to achieve systematic reuse, the technical and non-technical issues must be considered in parallel, and a set of component models should be built from different perspectives. Each of these models gives a specific view of the components so as to satisfy different needs of different persons involved in the enterprise reuse program. Especially, we present a reusable component model – FLP model for reusable component, which describes components from three dimensions (form, level, and presentation) and views components and their relationships from the perspective of process and management. This model determines the sphere of reusable components, the time points of reusing components in the development process, and the needed means to present components in terms of the abstraction level, logic granularity and presentation media. It is the basis on which the management and technical decisions are made. It will be used as the kernel model to initialize and normalize a systematic enterprise reuse program. After the FLP model, the relationships among these different models are discussed. Furthermore, the usage of these models to facilitate the perspective management of enterprise software reuse is discussed.

Three empirical studies of a software reuse reference model

The contribution of this paper is a reference model for the practice of software reuse. Our research thesis is that software development based upon a software reuse reference model improves quality of products, productivity of processes and product time‐to‐market for many software development enterprises. The definition and investigation of such a model has been carried out using three steps. First, the reference model is developed based on existing software reuse concepts. Second, this reference model is empirically studied using both legacy studies and lessons learned studies. Third, the impact of the reference model on software development productivity, quality, and time‐to‐market is empirically derived. Copyright © 2000 John Wiley & Sons, Ltd.     

A model for software reuse

Software reusability is widely believed to be a key to help overcome the ongoing software crisis by improving software productivity and quality. New computer technology and the demands of an advancing society require new and more complicated software. It is unrealistic to expect that every software system can be developed solely reusing existing software; however, software reusability has proven to be a way of enhancing software productivity and quality in different organizations. It is also believed that reuse of code segments alone does not significantly reduce software development effort.By creating reuse support information while software is being developed (when the software is best known to software developers), the reuse effort for both software development and maintenance can be potentially reduced.In this paper, five types of RSI are presented: Semantic Web, Horizontal Web, Vertical Web, Syntactic Web, and Alternative Web. We collectively call these five webs a Quintet Web. The Semantic Web enables software developers to locate a software segment. The Horizontal Web provides a means to reuse a block of soflware along with other types of software from other phases of a development process. The inter-phase integration of software can be performed through this Web. The Vertical Web identifies the vertical relationship of a software block to its operational environment. The Syntactic Web locates all statements in which a variable is used. The Alternative Web provides alternative software blocks that perform an identical operation.A prototype of the Quintet Web is presented.
