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．classesB．componentsC．sequencesD．artifacts
●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.

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.A.System logical modelingB.use case modelingC.requirements modelingD.application modeling A.systems planning phaseB.systems modeling phaseC.systems analysis phaseD.systems design phase A.system charterB.system scope definitionC.system blueprintD.system requirement document A.application architectureB.system data modelC.system process modelD.implement environment A.system architecture descriptionB.system design specificationC.system technique architectureD.physical deployment architecture
Software architecture reconstruction is an interpretive, jnteractive, and iterative process including many activities. （ ）involves analyzing a systems existing design and implementation artifacts to construct a model of it. The result is used in the following activities to construct a view of the system. The database construction activity converts the （ ） contained in the view into a standard format for storage in a database. The （ ）activity involves defining and manipulating the information stored in database to reconcile, augment, and establish connections between the elements. Reconstruction consists of two primary activities: （ ） and （ ）. The former provides a mechanism for the user to manipulate architectural elements, and the latter provides facilities for architecture reconstruction.A.Reverse engineering B.Information extraction C.Requirements analysis D.Source code analysis A.actors and use cases B.processes and data C.elements and relations D.schemas and tables A.database normalization B.schema definition C.database optimization D.view fusion A.architecture analysis and design B.domain analysis and static modeling C.visualization and interaction D.user requirements modeling A.pattern definition and recognition B.architecture design and implementation C.system architecture modeling D.dynamic modeling and reconstruction

During the systems analysis phase, greater user involvement usually results in better communication, faster development times, and more satisfied users.There are three common team-based approaches that encourage system users to participate actively in various development tasks.1) () is a popular fact-finding technique that brings users into the development process as active participants. The end product of the approach is a requirements model.2) () is a team-based technique that speeds up information systems development and produces a functioning information system. The approach consists of several phases. The (请作答此空) combines elements of the systems planning and systems analysis phases of tbe SDLC.Users, managers, and IT staff members discuss and agree on business needs, project scope, constraints, and system requirements. During (), users interact with systems analysts and develop models and prototypes that represent all system processes, outputs, and inputs.3) () attempt to develop a system incrementally by building a series of prototypes and constantly adjusting them to user requirements.A.requirements planning phase需求计划阶段B.business process modeling业务流程建模C.business process improvement业务流程优化D.scope definition phase范围定义阶段
