第4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.

第6题:

● Information systems design is defined as those tasks that focus on the specification of a detailed computer-based solution. Typically, there are four systems design tasks for in-house development.

1) The first task is to specify (71) , which defines the technologies to be used by one, more, or all information systems in terms of their data, processes, interfaces, and network components. This task is accomplished by analyzing the data models and process models that are initially created during requirements analysis.

2) The next systems design task is to develop the (72) . The purpose of this task is to prepare technical design specifications for a database that will be adaptable to future requirements and expansion.

3) Once the database prototype has been built, the systems designer can work closely with system users to develop input, output and dialogue specifications. The (73) must be specified to ensure that the outputs are not lost, misrouted, misused, or incomplete.

4) The fourth design task involves packaging all the specifications from the previous design tasks into a set of specifications that will guide the (74) activities during the following phases of the systems development methodology.

Finally, we should (75) and update the project plan accordingly. The key deliverable should include a detailed plan for the construction phase that should follow.

(71)

A. an application architecture

B. a distributed system

C. a system scope

D. a system physical model

(72)

A. database design specifications

B. database organization decisions

C. data structure specifications

D. data distribution decisions

(73)

A. format and layout

B. transaction details

C. additional instructions

D. internal controls

(74)

A. system administrator’s

B. system analyst’s

C. computer programmer’s

D. system designer’s

(75)

A. adjust the project schedule

B. reevaluate project feasibility

C. evaluate vendor proposals

D. select the best vendor proposal

Due to a constantly(71)environment, a poor understanding of the user's needs and preferences, as well as a(72)of willingness to modify(73)organizational structures and decision models, the full economic potential of Web.

Information Systems(WIS)has not been realized by now. The data object types of the(74)meta. model, the Extended World Wide Web Design Technique(EW3DT), provide hypertext designers(75)a conceptual, user-centric framework and graphical notation for the construction of both, reference and customized models, during the software development process of commercial WIS. A reference model as a normative concept represents an abstraction of a typical company, its functional units, or its(Web)Information Systems and is intended to streamline the design and implementation of complex applications at reduced costs. As precondition for pursuing a partial globalization strategy, EW3DT distinguishes between technical and content-specific responsibilities for designing, implementing, and maintaining WIS.
