Hispital Management的功能模块图和ER图怎么画？

画出Hospital ManageMent的功能模块图和ER图，并将ER图转换成具体的数据库和表格，写出SQL语句。

摘要 本文主要阐述了外科医疗信息管理系统的设计思路、实现过程和实现方法。最初，我们从系统面向的用户着手，了解不同用户的各种需求，从而分析得出系统应具备的功能，并依次设计系统的模块结构和功能联系。在分析用户需求时，我们同时分析了系统管理的对象——即系统要管理的数据，把这些数据按照功能分类形成表，完成了数据库的设计。后台程序中数据库的接口也是按数据表的结构来实现的。 根据教学信息管理的特点，系统采用浏览器/服务器（B/S）模式[1]，运用了基于C#语言的ASP.NET技术，以SQLSERVER 2005数据库作为后台数据库，使用Visual Studio 2005开发前台页面，实现了对外科医疗信息方便、快捷的管理，不仅提高了外科医疗信息管理的效率，而且为医院工作人员之间信息的交流提供了一个便捷的平台。 系统实现的功能模块主要有：系统管理员模块，医生管理模块，护士管理模块，科室秘书管理模块，手术中管理模块。系统把这些功能模块有机的组织起来，已经具备了较高的实用价值。    关键字：信息管理系统, ASP.NET, C#    ABSTRACTSomething about how to design a Surgical Medical Management Information System that will be used in a hospital is mainly discussed in this paper. Also, the process and technique for carrying out this system are described detailed. At first, we make a survey about the requirements of the client who is the user of this system and analyze the system to see what function should be included. Lastly we devise relations between different functions and work out modules of this project. Based on analysis of the object to the system, we classify these data according to their function and complete designing of the database. Interface of database in background program is done based on the structure of datasheet.  According to Surgical Medical Management Information System, we decide that mold of this project should be B/S mold and use ASP.NET that based on C# language. The database we selected is SQL Server 2005 and the web is developed by Visual Studio 2005 in foreground. So it is convenient and fast to run basis instruction information and the monitor can be implemented with great efficiency. A convenient flat for communication between Staffs in the hospital also be provided.  Primary
