在水土保持监测系统信息平台实现参数库、模型库与数据库分开管理、空间数据与非空间数据集成存储于关系型数据库中的基础上,为了避免数据更新不及时或不完备而造成数据信息过时,导致信息平台变成死库,需要信息平台更新维护系统.基于这一目标,文章集中探讨了信息平台管理维护系统的结构、功能、实现方法和关键技术.其中系统结构在信息平台服务结构基础上采用C/S模式;开发平台采用ArcGIS桌面产品,以对象COM组件技术ArcObjects为平台、MicroSoft Visual Basic为开发环境,进行二次开发.从而集后台数据库和前端数据管理、更新维护于一体而实现了水土保持监测系统信息平台,也为水土保持监测系统成功运行奠定了坚实的基础. 相似文献

Agile development processes are adaptive rather than predictive. Therefore, agile processes emphasize operational system code
rather than its documentation. To overcome the absence of comprehensive documentation artifacts, agile methods require constant
interaction between the system stakeholders. Ironically, however, some traditional documentation artifacts come to support
this kind of interaction. In this study, we examine the relationship between software and documentation. We develop an approach
that enables incorporating domain documentation to agile development, while keeping the processes adaptive. We also provide
a system design that actively uses domain knowledge documentation. These ideas have been applied through the implementation
and use of agile documentation support components. 相似文献

Agile development focuses on accommodating program evolution. It's important in design to consider those points of the system that likely undergoes substantial change. At such points, it's often appropriate to apply agile-programming techniques. Agile programming is design for change, without refactoring and rebuilding. Its objective is to design programs that are receptive to, indeed expect, change. Ideally, agile programming lets changes be applied in a simple, localized way to avoid or substantially reduce major refactorings, retesting, and system builds. 相似文献

Agile software testing in a large-scale project 总被引:1,自引:0,他引:1
《Software, IEEE》2006,23(4):30-37
Agile software development in general and Extreme Programming (XP) in particular, promote radical changes in how software development organizations traditionally work. We present and analyze new data from a real, large-scale agile project to develop a business-critical enterprise information system for the Israeli Air Force (IAF). Our results offer new evidence that agile testing practices actually work, dramatically improving development quality and productivity. We describe the organization's successful practices and guidelines in four key areas: test design and activity execution, working with professional testers, planning, and defect management. 相似文献

ContextWhile renowned agile methods like XP and Scrum were initially intended for projects with small teams, traditional enterprise environments, i.e. environments where plan-driven development is prevalent, have also become attracted by the promises of a faster time to market through agility. Agile software development methods emphasize lightweight software development. Projects within enterprise environments, however, are typically confronted with a large and complex IT landscape, where mission-critical information is at play whose criticality requires prudence regarding design and development. In many an organization, both approaches are used simultaneously.ObjectiveFind out which challenges the co-existence of agile methods and plan-driven development brings, and how organizations deal with those challenges.MethodWe present a grounded theory of the challenges of using agile methods in traditional enterprise environments, based on a Grounded Theory research involving 21 agile practitioners from two large enterprise organizations in the Netherlands.ResultsWe organized the challenges under two factors: Increased landscape complexity and Lack of business involvement. For both factors, we identify successful mitigation strategies. These mitigation strategies concern the communication between the agile and traditional part of the organization, and the timing of that communication.ConclusionAgile practices can coexist with plan-driven development. One should, however, keep in mind the context and take actions to mitigate the challenges incurred. 相似文献

Original equipment suppliers (OES) that develop unique products are continuously faced with changing requirements during both the quotation and product development processes. This challenge is a different reality from companies that develop off-the-shelf products for the end consumer, which use fixed specifications and where product platforms have been a strong enabler for efficient mass customization. However, product platforms cannot adequately support companies working as OES. The reason is that a high level of customization is required which means that interfaces cannot be standardized, the performance is not negotiable, requirements are not initially fixed, and the specific system interacts with, is affected by, or affects other systems that are simultaneously developed in a transdisciplinary environment. The design platform (DP) approach provides a coherent environment for heterogeneous and transdisciplinary design resources to be used in product development by supporting both designing and off-the-shelf solutions. This research describes the introduction, application and further development of the DP approach at an automotive supplier to support the development of customized solutions when traditional modularity or platform scalability do not suffice. A computer tool called Design Platform Manager has been developed to support the creation and visualization of the DP. The support tool has a connection to a product data management database to link the platform model to the various kinds of engineering assets needed or intended to support variant creation. Finally, the support tool was evaluated by the case company representatives showing promising results. 相似文献
