北京信息科技大学实验（上机）报告课程名称 UML及建模工具 学号 2012012194 姓名 李自然 成绩_专业名称信息安全实验室名称3-607实验时间15.6实验名称实验3： 使用类图进行面向对象建模1. 实验目的：1) 掌握UML类图建模的意义。2) 掌握Rational Rose或其他工具绘制类图的方法。3) 掌握对象关联关系的含义和表示。4) 掌握泛化、实现关系的含义和表示。5) 了解依赖关系的含义和表示。2. 实验内容：1) 根据附录源程序，绘制类图。2) 绘制ADO.NET主要对象（SqlConnection、SqlCommand、SqlParameter、DataReader、SqlDataAdapter、DataSet、DataTable、DataRow、DataColumn等）的类图（包含常用属性、方法、关系），可以参考MSDN帮助找到以上类的相关基类和接口。3) 根据/gzzd/rcpy/201405/t20140528_23261.html “荐优秀应届本科毕业生免试攻读硕士学位研究生遴选程序与办法”，请识别该领域的对象、属性以及它们之间的关系，绘制领域类图。（提示：学院、指标、学生、申请、审核、成绩、初选入围名单、公示资格名单、接收学校、申诉、资格取消等）4) 同步课程设计任务：多余时间小组成员共同讨论分析课题，寻找领域对象及其属性，绘制一张类图（成果不在本实验报告中上交）。3. 实验要求：1) 直接将类图拷贝粘贴到实验报告中提交。2) 正确使用类图中的关系，包括关联、泛化、实现和依赖，要求各种符号使用遵守UML语法规范。3) 个人独立完成。4) 提交最后期限：当日提交。4. 实验准备：1) 源程序2) Rational rose5. 实验过程和结果：6.1) 根据附录源程序，绘制类图7. 实验总结：通过这次试验，我学会了用工具画类图，并且更加熟练了根据程序画图附录：影片租赁源程序/租赁类的定义class Rental private Movie _movie; / 影片 private int _rentDate; / 租赁日期 private int _daysRented; / 租期public Rental(Movie movie, int daysRented) _movie = movie; _daysRented = daysRented; public int getDaysRented() return _daysRented; public Movie getMovie() return _movie; double getCharge() return _movie.getCharge(_daysRented); int getFrequentRenterPoints() return _movie.getFrequentRenterPoints(_daysRented); /顾客类的定义class Customer private String _name; / 姓名 private String _phone; / 电话号码 private Vector _rentals = new Vector(); / 租借纪录public Customer(String name) _name = name; public void addRental(Rental arg) _rentals.addElement(arg); public String getName() return _name; /输出租赁交易报告public String statement() Enumeration rentals = _rentals.elements(); String result = Rental Record for + getName() + n; while (rentals.hasMoreElements() Rental each = (Rental) rentals.nextElement(); /显示该顾客的每个租赁 result += t + each.getMovie().getTitle()+ t + String.valueOf(each.getCharge() + n; /结尾打印（总费用和积分） result += Amount owed is + String.valueOf(getTotalCharge() + n; result += You earned + String.valueOf(getTotalFrequentRenterPoints() + frequent renter points; return result; /已超文本方式输出租赁交易报告public String htmlStatement() Enumeration rentals = _rentals.elements(); String result = Rentals for + getName() + n; while (rentals.hasMoreElements() Rental each = (Rental) rentals.nextElement(); /显示该顾客的每个租赁 result += each.getMovie().getTitle()+ : + String.valueOf(each.getCharge() + n; /结尾打印（总费用和积分） result += You owe + String.valueOf(getTotalCharge() + n; result += On this rental you earned + String.valueOf(getTotalFrequentRenterPoints() + frequent renter points; return result; / 计算总积分private int getTotalFrequentRenterPoints() int result = 0; Enumeration rentals = _rentals.elements(); while (rentals.hasMoreElements() Rental each = (Rental) rentals.nextElement(); result += each.getFrequentRenterPoints(); return result; / 计算总费用private double getTotalCharge() double result = 0; Enumeration rentals = _rentals.elements(); while (rentals.hasMoreElements() Rental each = (Rental) rentals.nextElement(); result += each.getCharge(); return result; /抽象价格类的定义abstract class Price abstract int getPriceCode(); / 取得价格代号 abstract double getCharge(int daysRented); / 根据租期计算费用int getFrequentRenterPoints(int daysRented) / 根据租期计算积分 return 1; /儿童价格类的定义class ChildrensPrice extends Price int getPriceCode() return Movie.CHILDRENS; double getCharge(int daysRented) double result = 1.5; if (daysRented 3) result += (daysRented - 3) * 1.5; return result; /新片价格类的定义class NewReleasePrice extends Price int getPriceCode() return Movie.NEW_RELEASE; double getCharge(int daysRented) return daysRented * 3; int getFrequentRenterPoints(int daysRented) return (daysRented 1) ?
