支持地球科学的软件复用(英文)

地球科学研究中数据的准备、分发、访问、处理和分析都依赖于计算机软件。科学结果的重复通常需要复用同样的软件。同样,科学数据的有效分发、访问或者分析也都需要进行软件复用。地球科学软件开发社区已经意识到了软件复用的价值,并且在社区内大力鼓励和培育软件复用。因此,他们成立了 NASA 地球科学数据系统( ESDS) 软件复用工作组( WG) 来支持社区成员之间的软件复用。工作组开发了软件复用门户来发布软件复用相关的信息、资源,并且提供培训来提高和改进整个社区的软件复用实践。工作组还开发了一个复用支持系统( RES) 原型系统来支持可复用软件的访问。此外, 工作组还制定了复用成熟度级别, 从而提高了评估和选择可复用软件的能力。     

Trends in software reuse research: A tertiary study

ContextThe reuse of software has been a research topic for more than 50 years. Throughout that time, many approaches, tools and proposed techniques have reached maturity. However, it is not yet a widespread practice and some issues need to be further investigated. The latest study on software reuse trends dates back to 2005 and we think that it should be updated.ObjectiveTo identify the current trends in software reuse research.MethodA tertiary study based on systematic secondary studies published up to July 2018.ResultsWe identified 4,423 works related to software reuse, from which 3,102 were filtered by selection criteria and quality assessment to produce a final set of 56 relevant studies. We identified 30 current research topics and 127 proposals for future work, grouped into three broad categories: Software Product Lines, Other reuse approaches and General reuse topics.ConclusionsFrequently reported topics include: Requirements and Testing in the category of Lifecycle phases for Software Product Lines, and Systematic reuse for decision making in the category of General Reuse. The most mentioned future work proposals were Requirements, and Evolution and Variability management for Software Product Lines, and Systematic reuse for decision making. The identified trends, based on future work proposals, demonstrate that software reuse is still an interesting area for research. Researchers can use these trends as a guide to lead their future projects.     

The impact of software evolution and reuse on software quality

This paper presents a case study of a software project in the maintenance phase. The case study was based on a sample of modules, representing about 1.3 million lines of code, from a very large telecommunications system. Software quality models were developed to predict the number of faults expected from the coding through operations phases. Since modules from the prior release were often reused to develop a new release, one model incorporated reuse data as additional independent variables. We compare this model's performance to a similar model without reuse data.Software quality models often have product metrics as the only input data for predicting quality. There is an implicit assumption that all the modules have had a similar development history, so that product attributes are the primary drivers of different quality levels. Reuse of software as components and software evolution do not fit this assumption very well, and consequently, traditional models for such environments may not have adequate accuracy. Focusing on the software maintenance phase, this study demonstrated that reuse data can significantly improve the predictive accuracy of software quality models.

A domain-independent software reuse framework based on a hierarchical thesaurus

Software reuse is an effective way to improve software productivity and quality. Software libraries are getting bigger, while most of them, such as those for object-oriented languages, use simple but somewhat ineffective classification methods. These libraries typically provide search aids for novices, but not for experts. They are not flexible enough to adequately serve users with different abilities. In this paper, a Software Reuse Framework (SRF) for overcoming these drawbacks is proposed. Based on a built-in hierarchical thesaurus, the classification process can be made semi-automatic. SRF is a domain-independent framework that can be adapted to various libraries. SRF also provides four search levels to serve users with different skill levels. Two sample SRF systems are implemented, one for Smalltalk-80 and the other for MFC 4.0 (Microsoft® Foundation Class) libraries. © 1998 John Wiley & Sons, Ltd.     

Architectural Mismatch: Why Reuse Is Still So Hard

In this article, David Garlan, Robert Allen, and John Ockerbloom reflect on the state of architectural mismatch, a term they coined in their 1995 IEEE Software article, "Architectural Mismatch: Why Reuse Is So Hard." Although the nature of software systems has changed dramatically since the earlier article was published, the challenge of architectural mismatch remains an important concern for the software engineering field.

A metamodel for modeling system features and their refinement, constraint and interaction relationships

This paper presents a metamodel for modeling system features and relationships between features. The underlying idea of this metamodel is to employ features as first-class entities in the problem space of software and to improve the customization of software by explicitly specifying both static and dynamic dependencies between system features. In this metamodel, features are organized as hierarchy structures by the refinement relationships, static dependencies between features are specified by the constraint relationships, and dynamic dependencies between features are captured by the interaction relationships. A first-order logic based method is proposed to formalize constraints and to verify constraints and customization. This paper also presents a framework for interaction classification, and an informal mapping between interactions and constraints through constraint semantics.
