一种全面支持后续开发的嵌入软构件模型 总被引:1,自引:0,他引:1
基于构件的软件开发(CBD)逐渐成为嵌入式软件开发的主要开发方法之一.它能将构件开发的诸多优点(如降低开发成本,提高开发效率.缩短产品上市时间等)带入到嵌入式软件开发当中去.一个好的嵌入软构件模型能对基于构件的嵌入式软件的后续开发起到至关重要的作用.提出了一种嵌入软构件模型--ESCM.它能对之后的嵌入式软件构件的检索、组装及集成测试等提供有力的支持. 相似文献

模型检验是一种自动化验证技术,其应用主要的困难在于状态空间爆炸问题.针对构件组合形成的状态空间爆炸问题,结合构件抽象组合原理及反例引导的抽象精化框架,提出了一种测试用例自动生成的方法.根据某个待集成构件抽象已集成的其他构件,并通过组合各个抽象构件生成抽象组合模型.利用模型检验工具对组合模型进行集成测试,生成抽象测试用例,再通过精化得到原模型对应的具体测试用例.实验结果表明该方法减小了状态空间,在一定程度上减缓了状态空间爆炸的问题. 相似文献

The advantages of migrating from traditional monolithic business applications to reusable object-based business components (self-contained software that carries out a certain business task) are well documented. A business system assembled from reusable components is argued to be highly reliable since these components have been tested and used in many other business applications. However, all possible uses of components are not known at design and construction stage. Additionally, integration testing is needed as components are assembled to make business application systems. Component-based software development requires that testing issues be addressed adequately. In this paper, we explore testing related issues in business components and in particular, business application systems that are made by integrating these components. An integration test strategy for business component application systems is proposed. 相似文献

The component-based business architecture integration of military information systems is a popular research topic in the field of military operational research. Identifying enterprise-level business components is an important issue in business architecture integration. Currently used methodologies for business component identification tend to focus on software-level business components, and ignore such enterprise concerns in business architectures as organizations and resources. Moreover, approaches to enterprise-level business component identification have proven laborious. In this study, we propose a novel approach to enterprise-level business component identification by considering overall cohesion, coupling, granularity, maintainability, and reusability. We first define and formulate enterprise-level business components based on the component business model and the Department of Defense Architecture Framework (DoDAF) models. To quantify the indices of business components, we formulate a create, read, update, and delete (CRUD) matrix and use six metrics as criteria. We then formulate business component identification as a multi-objective optimization problem and solve it by a novel meta-heuristic optimization algorithm called the ‘simulated annealing hybrid genetic algorithm (SHGA)’. Case studies showed that our approach is more practical and efficient for enterprise-level business component identification than prevalent approaches. 相似文献

While constructing virtual enterprises, it is crucial to flexibly integrate heterogeneous business resources and processes of different business partners and make them collaborate dynamically. Keeping involved IT systems or components as autonomous and loose-coupled services, the “Everything as a Service” concept supports flexible integration of heterogeneous applications. We adopt this concept and analyze the challenges in virtual enterprise construction, then propose a service platform for on-demand virtual enterprises. The platform supports flexible integration of networked resources, and facilitates virtual enterprise construction with business process utility, trusted service composition and data service centric business collaborations. At the end of the paper, together with a case study, experimental evaluations in contexts of concurrent multi-users are presented, showing the effectiveness and performance of the platform. 相似文献

This paper gives a synopsis of the SAP R/3 Business Framework. The architecture is based on an object-orientated approach using business objects and Business Components. Using this architecture together with a distribution model, distributed applications (distributed business processes) can be mapped and implemented. The spectrum of distributed applications extends from the simple integration of two components using a few interfaces to the integration of many components distributed across the globe. 相似文献
