ssm医院门诊互联电子病历管理信息系统源码和论文

摘  要

网络的广泛应用给生活带来了十分的便利。所以把医院门诊互联电子病历管理与现在网络相结合,利用java技术建设医院门诊互联电子病历管理信息系统,实现医院门诊互联电子病历的信息化。则对于进一步提高医院门诊互联电子病历管理发展,医院门诊互联电子病历管理系统能起到不少的促进作用。

医院门诊互联电子病历管理信息系统能够通过互联网得到广泛的、全面的宣传,让尽可能多的用户了解和熟知医院门诊互联电子病历管理信息系统的便捷高效,不仅为群众提供了服务,而且也推广了自己,让更多的群众了解自己。对于医院门诊互联电子病历而言,若拥有自己的系统,通过系统得到更好的管理,同时提升了形象。

系统设计的现状和趋势,从需求、结构、数据库等方面的设计到系统的实现,分别为管理员、医生和用户实现。论文的内容从系统的设计、描述、实现、分析、测试方面来表明开发的过程。本系统根据现实情况来选择一种可行的开发方案,借助java编程语言和MySQL数据库等实现系统的全部功能,接下来对系统进行测试,测试系统是否有漏洞和测试用户权限来完善系统最终系统完成达到相关标准。

Abstract

The wide application of network has brought great convenience to life. Therefore, the hospital outpatient electronic medical record management and the current network combined, using Java technology to build the hospital outpatient electronic medical record management information system, to achieve the hospital outpatient electronic medical record information. It can further improve the development of electronic medical record management in hospital outpatient department and promote the electronic medical record management system in hospital outpatient department.

Hospital outpatient interconnected electronic medical record management information system can widely through the Internet and comprehensive propaganda, for as much as possible the user to understand and be familiar with the hospital outpatient service interconnected electronic medical records management information system is convenient and efficient, not only provide the service for the masses, but also to promote yourself, let more people know about themselves. For the connected electronic medical record of hospital outpatient department, if it has its own system, it can get better management through the system and improve its image.

The present situation and trend of the system design, from the requirements, structure, database and other aspects of the design to the realization of the system, respectively for the realization of administrators, doctors and users. The content of the paper shows the development process from the aspects of system design, description, implementation, analysis and testing. The system according to the reality to choose a feasible development plan, with the help of Java programming language and MySQL database to achieve all the functions of the system, then the system is tested, test whether the system has vulnerabilities and test user permissions to improve the system, the final system to achieve relevant standards.

Key words: Hospital out-patient interconnect electronic medical record management information system Java MySQL database
