Design And Implementation Of The Interface Subsystem Of A Health Insurance Information System

The health insurance system is an important part of the social security system. The improvement of the health insurance mechanisms reflects the degree of social progress to a certain extent. With the development of information technology and the Internet, the use of the health insurance information system makes the operation more efficient, fast, convenient. As the important component of a health insurance system, the interface subsystem is a bridge between the hospital and the medical insurance settlement center and is a carrier that conveys the health insurance policy. A good interface subsystem is a key to keep a health insurance system running healthy and stable. Therefore, the medical institutions at all levels have paid more attention to the design and construction of the interface of a health insurance system.This thesis first describes the medical insurance information system and its development at home and abroad. Then the significance and the research contents of this thesis are introduced. A hospital called "A" in Guizhou Province is adopted as the object of study. Through the research of the hospital business processes, the UML object-oriented analysis method is used to obtain a comprehensive need analysis of the interface subsystem. Based on these results the design principle and goal of the subsystem are determined. Combined with the function characteristics of the hospital business management and the actual requirements of the subsystem, the system function structure is designed in detail. At the same time the corresponding database system is designed and the system use case model and system sequence diagram are developed. According to the design scheme, combined with the characteristics of each module itself, this thesis gives the focus on the implementation techniques of the interface subsystem.Finally, the black box test method is adopted to design the whole test cases. Based on these test cases, the interface subsystem has been tested more comprehensively. Test results show that the interface subsystem developed has achieved the desired design objectives.
