摘要: |
系统的组成及其结构是体系结构中的一个核心元素,系统内聚度是评价信息系统体系结构的一个重要指标。以体系结构框架为基础,给出系统接口和系统功能的规范化描述。从功能和数据关系的角度,分别定义了系统功能内聚度和数据内聚度的计算方法,提出一种体系结构中系统内聚度的分析方法,并通过一个实例说明了方法的应用。该方法有助于规划系统和分配功能,提高体系结构设计质量。 |

Abstract: |
System cohesion is an important evaluation factor in information system architecture. Based on the architecture framework, the formal description of system interfaces and system functions were provided. In terms of functions and data relationships, the function cohesion and data cohesion were defined respectively, and the system cohesion evaluation method was proposed. Furthermore,an application example was presented.The method is helpful in system design, function assignment, and improving the quality of architecture development. |
Keywords: system cohesion system functions architecture |
