基于面向对象的医院收费管理信息系统的分析与设计.doc

【摘要】医院信息系统属于迄今世界上现存的企业级信息系统中最复杂的一类。传统的基于客户机/服务器的HIS产品开发周期长，而且功能上也不够完善，存在着诸如系统响应速度慢，难以集中控制，可扩展性差等各种各样的问题。因此，需要一种科学的方法来分析和设计医院信息系统。本文讨论的医院门诊收费系统就采用了面向对象建模的技术和方法，能够较好地捕捉用户的需求，为系统的成功开发和软件的后期维护莫定了良好的基础。 本文利用面向对象技术分析和设计了医院收费管理信息系统，包括从需求分析、架构设计、测试提交，完成门诊收费系统，具体有：在需求模型中，通过用例图从外部用户的角度来捕获系统、子系统或类的行为；在系统分析模型中，主要通过顺序图描述对象间的交互关系、对象的生命周期以及生命周期中对象可能存在的状态以及状态间的转换约束；在系统设计模型中，通过类图定义系统对象及对象间的静态关系；在系统体系架构模型中，通过系统体系架构图来描述系统的多层体系架构；在系统实现模型中，通过配置图描述软件体系架构、硬件体系架构以及通信机制。 【关键词】门诊收费系统，UML，面向对象【Abstract】Hospital information system is by far the worlds most complex existing enterprise information systems. Traditional client / server-based HIS product development cycle, and the function is not perfect, there is a slow speed, such as system response, it is difficult to centralized control, scalability, and poor variety of problems. Therefore, you need a scientific approach to analysis and design of hospital information systems. This article discusses the hospital outpatient charges on the use of object-oriented modeling techniques and methods, and better able to capture the users needs, and laid a good foundation for the latter part of the success of the system development and software maintenance. In this paper, object-oriented technology analysis and design of hospital charges and management information systems, including requirements analysis, architecture design, test submitted to complete the out-patient charges system, specifically: the demand model, through the use case diagram from the perspective of external users to capture system, subsystem, or class of acts; in the system analysis model, mainly through the sequence diagram describes the interactions between objects, object life cycle, and the status of objects that may exist in the life cycle and transitions between states are constrained; in the system design model defined by the class diagram in the system objects and the static relationships between objects; system architecture model, system architecture diagram to describe the sy
