摘要

随着时代的发展，医疗设备愈来愈完善，医院也变成人们生活中必不可少的场所。如今，已经2021年了，虽然医院的数量和设备愈加完善，但是老龄人口也越来越多。在如此大的人口压力下，医院住院就变成了一个问题。目前预约住院看病住院在国内已经是一种习惯了，在欧美国家，除了急诊，患者看病一般都采取预约住院，而且国外的网上预约技术已经较为成熟。随着互联网网络的迅猛发展，网络用户已经越来越多，网上预约住院也应该成为医院住院的主流方式了。网上预约住院系统是一种基于互联网的新型住院系统。使用预约住院系统，用户就可以在网上预约医院的专家、专科号。它能更好的改善就医环境，简化就医环节，节约就医时间，真正体现了以病人为中心，切从方便患者出发，符合当今医院人性化温馨服务的理念。本医院住院管理系统采用的数据库是Mysql，使用SSM框架开发。在设计过程中，充分保证了系统代码的良好可读性、实用性、易扩展性、通用性、便于后期维护、操作方便以及页面简洁等特点。
