简单的职工管理系统

1 课程设计任务与要求 1.1 课程设计目的

《数据结构》是计算机专业一门重要的专业技术基础课程。本课程较系统地介绍了软件设计中常用的数据结构以及相应的存储结构和实现算法，介绍了常用的多种查找和排序技术。本课程将为整个专业的学习以及软件设计水平的提高打下良好的基础。为了学好《数据结构》，必须掌握编写一些在特定数据结构上的算法，并通过上机调试，更好地掌握各种数据结构及其特点，此次《数据结构》课程设计目的正在于此。

经过本次课程设计，我们对于数据结构基本理论和存储结构及算法设计将有更加深入的理解，并提高我们在实际设计操作中系统分析、结构确定、算法选择、数学建模和信息加工的能力，提高我们的C/C++语言程序设计能力，以及培养学我们编写程序设计文档的能力。

1.1.1 问题描述

根据题目要求，由于职工信息是存放在文件中，所以应提供文件的输入、输出等操作；在程序中需要浏览职工的信息，应提供显示、查找、排序等操作；另外还应提供键盘式选择菜单实现功能选择。

1.1.2 详细要求

（1）问题说明

设计一个简单的职工管理系统，按照课程设计的要求，实现对职工信息的新增、修改、插入、删除、以及排序操作。

（2）输入要求

由系统管理员依次输入现有职工和新增职工的以下信息：姓名（可以重复）、性别、出生年月、工作年月、学历、职务、地址、电话等信息，并且注意输入时姓名、学历、职务、地址为字符串形式，性别为字符，其余的为长整型数字。

（3）输出要求

系统管理员根据公司的人员流动情况，选择系统提供的各项功能进行操作，并输出

相应的结果。

1.2 问题分析

（1）具体要求

简单的职工管理系统主要实现以下功能：

① 新增一名职工：将新增职工对象按姓名以字典方式职工管理文件中。 ② 删除一名职工：从职工管理文件中删除一名职工对象。 ③ 查询：从职工管理文件中查询符合某些条件的职工。 ④ 修改：检索某个职工对象，对其某些属性进行修改。 ⑤ 排序：按某种需要对职工对象文件进行排序。

要求：职工信息包括姓名、性别、出生年月、工作年月、学历、职务、住址、电话等信息。

（2）实现提示：

① 由键盘输入职工对象，以文件方式保存。程序执行时先将文件读入内存。 ② 对职工对象中的\姓名\按字典顺序进行排序。

③ 对排序后的职工对象进行增、删、查询、修改、排序等操作。

2 概要设计 2.1 总体设计思想

根据职工管理系统问题的描述和详细需求分析，要达到上述功能，链表的数据结构来存储职工信息，并对其进行相应的插入、删除、修改、查询、排序、保存等操作。

（1）输入功能的实现：要想实现职工管理系统的输入，必须要建立一个职工信息系统的抽象数据类型，其中职工信息以链表的存储方式实现。

（2）系统处理功能的实现：系统管理员根据公司的人员流动情况，在提示信息的提示下，选择相应的服务进行操作。

（3）输出的实现：根据选择的操作，输出与之对应的信息。 综上可以绘制出职工管理问题的系统流程图，如图1所示

2.2 系统功能设计

根据职工管理系统问题的分析和设计要求，可以得到该职工管理系统可以分为五个模块：职工信息添加模块、职工信息修改模块、职工信息删除模块、职工信息查询模块、职工信息排序模块。其系统功能结构如图2所示。
