A Model Transformation Approach for Automatic Composition of COTS User Interfaces in Web-Based Information Systems

Globalization of the information and the Knowledge Society requires the modernization of Web-based Information Systems (WIS) into evolutive and adaptable user interfaces. Today, WIS user interfaces are built following traditional development paradigms. This article is inspired on a Model-Driven Development (MDD) perspective to produce runtime automatic composition of user interfaces from model and metamodel representations of widgets-type COTS interface components architectures and model transformation.

COTS技术在声呐装备中的应用

采用商业货架产品(Commercial-Off-The-Shelf,COTS)技术可使声呐系统具有更强的信号处理能力,有效降低声呐研制与更新成本,缩短声呐研制周期。分析了国外先进声呐系统上采用的COTS软硬件技术,对COTS技术在声呐系统中的应用前景进行了分析和展望,提出了我国声呐系统中COTS技术的重点研究方向,以加快发展拥有自主知识产权的COTS软硬件技术,提高我国海军声呐装备水平。     

COTS技术应用对军用ATE的影响

COTS（commercial off-the-shelf)作为20世纪80年代欧美主要军事大国提出的称为“商用现成技术”，这一概念，是相对于军用技术产品开发研制而言的。主要讨论COTS技术应用对军用ATE技术开发的影响，及为军用ATE带来的经济效益，并对我军应用COTS开发ATE的实际情况提出应注意的几个问题。     

COTS tenders and integration requirements

When buying COTS-based software, the customer has to choose between what is available. The supplier may add some minor parts, but rarely everything the customer wants. This means that the customer cannot write down his requirements and expect that they can all be met. A scoring system is necessary rather than traditional mandatory requirements. Requirements for integrating the new COTS system with other systems are particularly hard because suppliers may integrate in different ways and with different other systems. A related problem is that once the new COTS system is purchased, the COTS supplier may have a de facto monopoly. Only he can expand the system or integrate it with other systems. The traditional way to purchase COTS is to iteratively find the right product. However, in a tender process this is not possible, and another solution is necessary. Experience shows that customers fail to deal with these issues adequately. As an example they may believe that asking for open interfaces is sufficient to guard them against monopoly. In this paper we analyze the problems and show ways to deal with them. We illustrate the problems and solutions with real-life examples from electronic patient recording systems.     

COTS组件的非功能需求研究

针对COTS组件和需求工程中的非功能需求的特点,本文对COTS组件的非功能需求进行了研究和定义,提出了COTS组件的非功能需求应该包括结构需求、领域需求和组织需求,对这三种需求研究应该进行综合考虑,其中列出了组织需求应该包括的内容.     

一个软件复用成本模型对COTS、PLE和TTM的拓展

对当前存在的4种软件再利用模型进行分析,并对现有模型的优缺点进行比较,发现它们的共性及存在的问题是:不能涵盖目前软件复用的最新领域.以Chmiel的综合再利用模型为基础,将其推广和扩展到COTS(Commercial Off The Shelf)和生产线工程(PLE),并把进入市场时间(TTM)的成本和利益整合进去.基于这样的原理,这个模型能涵盖到软件复用领域当前最新的行为,包括COTS、PLE and TTM.     

商业构件评价与选择方法研究

在基于商业构件（COTS）的软件开发中，构件的评价与选择是贯穿整个开发过程的关键步骤。有两类典型的基于COTS的系统，即COTS方案系统和COTS密集型系统。本文首先描述了针对COTS方案系统的单构件评价问题的特点，并对各种评价方法进行了分析、对比。然后将COTS密集型系统的多构件选择问题定义为一个在给定的约束条件下求解最佳构件组合的数学优化问题。最后给出了该优化问题的形式描述及其相应的求解方法。     

A style for integrating MS‐Windows software applications to client–server systems using Java technology

Developing software systems by integrating the existing applications/systems over the network has become an established and practical technique. The Microsoft (MS) Windows operating systems today support a huge number of software applications. If these commercial applications could be transformed to software components, this may accelerate the construction of new components. This paper proposes an architectural style to support a three‐phase process for integrating MS‐Windows applications in a distributed system using Java technologies. This style provides a solution with clear documentation and sufficient information that is helpful for the rapid integration of MS‐Windows applications. Finally, an exemplary graphical construction part management system that assembles two MS‐Windows applications was developed in this study to demonstrate the feasibility of this style.
