第4题:

●The traditional model for systems development was that an IT department used (71)which is a process-centered technique, and consulted users only when their input or approval was needed. Compared with traditional methods, many companies find that JAD allows key users to participate effectivelyin the (72). When properly used, JAD can result in a more accurate statement of system requirements, a better understanding of common goals and a stronger commitment to the success of the new system. RAD is a team-based technique that speeds up information systems development and produces a functiog.information system. Whilethe end productof jAD is a(an)(73),theendproduct of RAD is the (74) .The RAD model consists offour phases. During the(75),users interact with systems analysts and develop models and prototypes that represent all system processes, outputs, and inputs.

B. object-oriented analysis

C. prototype analysis

D. process analysis

(72) A. initial scope definition

第5题:

对系统的静态用例视图建模时,可以用下列两种方式来使用例图,它们是(16)。

A.对系统的原型化实例建模和对传递的消息建模

B.对系统的消息建模和对数据建模

C.对系统的语境建模和对系统的需求建模

D.对系统的语境建模和对数据建模


正确答案:C
解析:用例图用于对系统的静态用例视图进行建模。这个视图主要支持系统的行为,即该系统在它的周边环境的语境中所提供的外部可见服务。当对系统的静态用例视图建模时,可以用下列两种方式来使用用例图。(1)对系统的语境建模对一个系统的语境进行建模包括围绕整个系统画一条线,并声明有哪些参与者位于系统之外并与系统进行交互。在这里,用例图说明了参与者及其所扮演的角色的含义。(2)对系统的需求建模对一个系统的需求进行建模,包括说明这个系统应该做什么(从系统外部的一个视点出发),而不考虑系统应该怎样做。在这里,用例图说明了系统想要的行为,通过这种方式,用例图使我们能够把整个系统看作一个黑盒子。你可以观察到系统外部有什么,系统怎样与那些外部事物相互作用,但却看不到系统内部是如何工作的。

第6题:

在统一建模语言(Unified Modeling Language,UML)中,描述本系统与外部系统及用户之间交互的图是(34);按时间顺序描述对象间交互的图是(35)。

A.用例图

B.类图

C.对象图

D.状态图


正确答案:A

第9题:

For nearly ten years, the Unified Modeling Language (UML) has been the industry standard for visualizing, specifying, constructing, and documenting the(71) of a software-intensive system. As the(72) standard modeling language, the UML facilitates communication and reduces confusion among project(73) . The recent standardization of UML 2.0 has further extended the language's scope and viability. Its inherent expressiveness allows users to(74) everything from enterprise information systems and distributed Web-based applications to real-time embedded systems.

The UML is not limited to modeling software. In fact, it is expressive enough to model(75) systems, such as workflow in the legal system, the structure and behavior. of a patient healthcare system, software engineering in aircraft combat systems, and the design of hardware.

To understand the UML, you need to form. a conceptual model of the language, and this requires learning three major elements: the UML's basic building blocks, the rules that dictate how those building blocks may be put together, and some common mechanisms that apply throughout the UML.

A.classes

B.components

C.sequences

D.artifacts


正确答案:D

第10题:

The purpose of systems analysis phase is to build a logical model of the new system. The first step is( ), where you investigate business processes and document what the new system must do to satisfy users. This step continues the investigation that began during the( ). You use the fact-finding results to build business models, data and process models, and object models. The deliverable for the systems analysis phase is the( ), which describes management and user requirements, costs and benefits, and outlines alternative development strategies. The purpose of the systems design phase is to create a physical model that will satisfy all documented requirements for the system. During the systems design phase, you need to determine the( ), which programmers will use to transform the logical design into program modules and code. The deliverable for this phase is the( ), which is presented to management and users for review and approval.
