Web development: estimating quick-to-market software 总被引:2,自引:0,他引:2
Developers can use this new sizing metric called Web Objects and an adaptation of the Cocomo II model called WebMo to more accurately estimate Web based software development effort and duration. Based on work with over 40 projects, these estimation tools are especially useful for quick-to-market development efforts 相似文献

Teaching systematic object-oriented software development to undergraduate students is difficult: Students need to develop a lot of complex skills. These include technical skills in object-oriented software development, but also social skills—for example, how to collaborate with other developers as part of a team working towards a large and complex software system. To acquire these skills, students need hands-on development experiences—for example, through team-oriented project courses. Designing such project courses is a challenge in itself: They must be both sufficiently challenging and achievable within the limited time available. In our special situation (large numbers of students supervised by small numbers of staff) an important further requirement is scalability: Different projects should be easily comparable while allowing for different tasks for different teams to reduce the risk of plagiarism. The solution that in our experience satisfies all these requirements is to use an application framework for an everyday application domain—for example, the business domain.Since 1997, we have been using Salespoint, a Java-based framework for creating business applications, that has been jointly developed and maintained in Dresden and Munich. In this paper, we briefly recollect the educational background and aims of the courses and present in some detail Salespoint (and its most recent revision, Salespoint2010): central notions like catalogs and stocks, the functionality it offers to users (application control, data management, and much more), a technical overview of its architecture, an example application built with Salespoint, and some lessons learned so far. 相似文献

为提高项目开发的效率,对Spring新特性Java Config在Web开发中的应用作了深入研究。以传统的使用XML配置Spring的方式为对比,对新特性Java Config的使用方法和其优势作了介绍。以实际案例的形式具体描述了Spring中XML配置方式和Java Config配置的方式。结果表明,Java Config在Web项目开发中具有操作简单、编译器错误检查、更符合程序员编程规范等优势。使用Java Config的方式还可以配合Servlet3.0完全去掉传统Web项目中固有的web.xml文件。Java Config将成为Web开发的流行趋势。 相似文献

When confronted with a new technology, we instinctively consider it within the context of existing work and practices. Such is the case with the World Wide Web. But the Web is more than a new technology for leveraging existing work. It is, in fact, an enabling technology with the potential to change software development as dramatically as the transistor and microprocessor changed computer architecture. An enabling technology changes the fundamental assumptions ingrained in a discipline. The microprocessor, for example, changed the reliability, cost, circuit density, and performance assumptions underlying hardware design. As a result, new applications and design approaches for hardware systems became feasible. Just as the microprocessor changed the fundamental assumptions of hardware design, the Web changes some of the assumptions underlying software development. Thus it has the potential to change our notion of the software artifact and the collaborative processes used to construct it 相似文献

运用JAVA处理Web信息流 总被引:1,自引:1,他引:1
李宁 《计算机工程与应用》2004,40(5):166-169,199
Web信息流量的变化,反映了Web用户对Web服务器的访问,具有长期的、周的、日的、时的和瞬间的随机变化特性。该文用快速Fourier变换(FFT)和统计分析结合的方法来处理Web流量变化的情况。FFT用于分析Web流量变化的确定性(即周期性)部分,统计理论用于分析Web流量变化的随机部分。整个处理系统通过JAVA编程实现。这里采用从实际的Web服务器采集的一列数据(“每秒用户请求数”),作为这个系统的输入,处理结果则通过系统的图形界面输出。该分析处理方法可以广泛地用于Web信息流量的预测、流量负载的动态分流、Web服务器的调配、网络容量的设计和最优规划、服务质量(QoS)性能保证和服务水平协商(SLAs)。该文提出并实现的分析方法和技术也可以应用到其它类型的数据处理。 相似文献

Developers using third party software components need to test them to satisfy quality requirements. In the past, researchers have proposed fault injection testing approaches in which the component state is perturbed and the resulting effects on the rest of the system are observed. Non-availability of source code in third-party components makes it harder to perform source code level fault injection. Even if Java decompilers are used, they do not work well with obfuscated bytecode. We propose a technique that injects faults in Java software by manipulating the bytecode. Existing test suites are assessed according to their ability to detect the injected faults and improved accordingly. We present a case study using an open source Java component that demonstrates the feasibility and effectiveness of our approach. We also evaluate the usability of our approach on obfuscated bytecode. 相似文献
