第1题：

The objective of （）is to determine what parts of the application software will be assigned to what hardware.The major software components of the system being developed have to be identified and then allocated to the various hardware components on which the system will operate. All software systems can be divided into four basic functions. The first is（）. Most information systems require data to be stored and retrieved,whether a small file,such as a memo produced by a word processor,or a large database,such as one that stores an organization’s accounting records. The second function is the （）,the processing required to access data,which often means database queries in Structured Query Language. The third function is the （）,which is the logic documented in the DFDs,use cases,and functional requirements.The fourth function is the presentation logic,the display of information to the user and the acceptance of the user’s commands.The three primary hardware components of a system are （）.

第4题：

An application architecture specifies the technologies to be used to implement one or more information systems. It serves as an outline for detailed design, construction, and implementation. Given the models and details, include （）, we can distribute data and processes to create a general design of application architecture. The design will normally be constrained by architecture standards, project objectives, and （请作答此空）. The first physical DFD to be drawn is the （）. The next step is to distribute data stores to different processors. Data（）are two types of distributed data which most RDBMSs support. There are many distribution options used in data distribution. In the case of（）, we should record each table as a data store on the physical DFD and connect each to the appropriate server.

A.the database management system
B.the feasibility of techniques used
C.the network topology and technology
D.the user interface and process methods

答案：B

解析：

应用架构说明了实现一个或多个信息系统所使用的技术，它作为详细设计、构造和实现的一个大纲。给定了包括逻辑数据流图和实体联系图在内的模型和详细资料，我们可以分配数据和过程以创建应用架构的一个概要设计。概要设计通常会受到架构标准、项目目标和所使用技术的可行性的制约。需要绘制的第一个物理数据流图是网络架构数据流图。接下来是分配数据存储到不同的处理器。数据分区和复制是大多数关系型数据库支持的两种分布式数据形式。有许多分配方法用于数据分布。在不同服务器上存储特定表的情况下，我们应该将每个表记为物理数据流图中的一个数据存储，并将其连接到相应的服务器。
