基于.NET的三层构架的护理文书系统的设计与实现
.NET框架是一个多语言组件开发和执行环境，它提供了一个跨语言的统一编程环境。
基于三层架构的护理文书系统只要分为三部分，客户端、中间服务器和数据库，中间服务器起到了缓解服务器压力的作用。系统采用模块化的设计，逐个完成登录、主界面、护理文书、业务逻辑层、数据访问层等。复用模块的采用继承基类的方式，使系统更加适应繁杂多变的护理文书。
三层架构的护理文书系统将代替传统的纸质文书，减少医疗纠纷，提高护士的工作效率，带动医院信息化的发展。

Based On .NET Three-layer Architecture Of Nursing Documents System Design And Implementation
Abstract: Three layer architecture is a C/S architecture, including user interface, functional process logic (business rule), computer data storage and data access are usually on different platform development and maintenance of independent modules. Three layer architecture is divided into the presentation layer, business logic layer and data layer.
The .NET framework is a multi-language component development and execution environment, it provides a unified programming across language environment.
Nursing documents system based on three-tier architecture as long as it is divided into three parts, among the client, server and database, alleviate the pressure of the server's role in the intermediate server. System adopts modular design, one by one to complete the login, the main interface, nursing documents, business logic layer, data access layer, etc. Reuse module adopts inherited base class method, make the system more adaptable to complicated and changeable nursing documents.
Three layer architecture of nursing documents system will replace the traditional paper-based documents, reduce medical disputes, improve the work efficiency of nurses, lead to the development of hospital informationization.
