Problems solved by technology

[0004] However, for a heterogeneous and large-scale complex information system composed of software, hardware, equipment, personnel and other elements, software is only one of the modules, so the concept and calculation method of coupling degree in the field of software engineering cannot be copied and used. There is no ready-made coupling degree calculation method in the technology that can provide guidance for the design of complex information systems
[0005] There is no effective solution to the problem that the calculation method without coupling degree in the prior art can provide support for the design of complex information systems

Abstract

The invention discloses a method and device for computation of a system coupling degree. The method comprises the steps that a system design data document is acquired and analyzed, and a system structure constitution table, a system interface relation constitution table and a system internal information transmission statistical table are established in a designed format according to the system design data document; according to the system structure constitution table and the system interface relation constitution table, atomic systems are selected, interface relations between the atomic systems are determined, and intactness of interface relations inside the system is verified; and according to the system interface relations between the atomic systems and the system internal information transmission statistical table, the coupling degree of the system can be computed. According to the invention, an effective supporting method is provided for measurement and evaluation of correlation intensity between system modules. Hence, analysis of a complexity degree of a complicated information system can be guided.

Description

technical field [0001] The invention relates to the field of information system engineering, in particular to a system coupling degree calculation method and device. Background technique [0002] With the development of information technology and the increasingly widespread application of information systems, the functions of information systems and the interrelationships within the system are becoming increasingly complex. The degree of coupling reflects the strength of the connection established between the system modules through connections. In the system, the closer the connection between the internal modules, the stronger the coupling, the harder it is to understand and modify the system, and the more complex the system will be. It can be seen that the degree of system coupling has an important impact on the quality attributes of the system, such as understandability, independence, testability, maintainability, and reliability, and is an important factor affecting the ...
