第4题：

The objective of (71) 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 (72). 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 (73), the processing required to access data, which often means database queries in Structured Query Language. The third function is the (请作答此空), 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 (75).


A. system requirements
B. system architecture
C.application logic
D.application program

答案：C
解析：
架构设计的目标是确定应用软件的哪些部分将被分配到何种硬件。识别出正在开发系统的主要软件构件并分配到系统将要运行的硬件构件。所有软件系统可分为四项基本功能。首项是数据存储。大多数信息系统需要数据进行存储并检索，无论是一个小文件，比如一个字处理器产生的一个备忘录，还是一个大型数据库，比如存储一个企业会计记录的数据库。第二项功能是数据访问逻辑，处理过程需要访问数据，这通常是指用SQL进行数据库查询。第三项功能是应用程序逻辑，这些逻辑通过数据流图，用例和功能需求来记录。第四项功能是表示逻辑，给用户显示信息并接收用户命令。一个系统的三类主要硬件构件是客户机、服务器和网络。
