基于大型数据库的医院信息系统设计与实现

The Design and Implementation of the Hospital Management System Based on Large-scale Database

通过对医院信息系统进行分析,形成了核心的业务流程图和功能模块图;比较了传统C/S和三层C/S两种模式,从医院实际出发,设计了基于三层C/S模式体系结构;根据数据需求,设计了数据库的基本结构,并采用oracle进行实现;实现时采用ADO.NET技术和数据库中的存储过程,保证了数据访问的高效、安全。该系统已在某医院中使用,并向其他同类医院扩展。

Through analysis of the hospital information system,designing the core business flow chart and functional module chart;Com paring the two modes of the traditional C/S and three-layers C/S,combining the reality of hospital,the system adopts the three-layer C/S structure;According to the data requirements,this paper designed the basic structure of database,and realized the database in oracle;In real ization we adopt ado.net technology and the storage procedure object to ensure the efficiency and safety of system.This system has been used in a hospital,and will expand to other similar hospital.
