基于Tomcat的手术安排计划系统的设计与实现

Design and Implementation of Operation Schedule System based on Tomcat

在我所工作的医院的心内科的医生为我提出了这样的一种需求：两个心内科病区的医生需要每天安排一些病人在两个导管室做手术,每个医生都有浏览、修改本病区所在导管室手术计划的权限,病人的常规信息由HIS数据库中直接提取。根据医生的需求,考虑有两种方式实现,第一种是利用PowerBuilder等开发工具开发应用程序客户端的C/S结构,第二种是基于网络HTTP服务器的B/S结构。本文选择了后者,且设计并实现了一个基于ApacheTomcat服务器的动态网络应用,对比利用应用程序客户端的实现方式,B/S结构有如下优点：客户端无需安装软件即可使用现成的功能;只要拥有用户名、口令可以在网络的任何位置使用系统;无需关心软件升级问题;使用数据库连接池,提供高效、稳定的数据库访问。

Doctors of cardiology department in the hospital where I work in demand that they need to arrange operation schedule of many patients every day. Each doctor can browse and edit the schedule of the region he belongs. The general information of patient can be retrieved from HIS database. There are two methods to implement such a system： C]S mode with clients created by PowerBuilder or some tools else; or B/S mode based on HTTP server. I choose the latter because it has several advantages. First, no installation on client side; Second, A doctor can access it from anywhere with user name and password; Third, client never worries about upgrading; Fourth, connection pool provides efficient, steady access on database.
