1、基于C#+Oracle的考勤管理系统的设计与开发年 级： * 学 号： * 姓 名： * 院 系： * 专 业： * 基于C#+Oracle的考勤管理系统的设计与开发一、系统设计基本情况1 系统设计目标利用计算机管理考勤信息，在很大程度上减轻了统计的工作量，实现企业员工考勤管理的规范化，考勤数据统计的自动化。2 设计思想除了能够手工录入员工的考勤记录外，还能与考勤机相配合，实现考勤信息录入自动化；考勤类型灵活设定，以便用户随时调整应具有报表功能，查询统计时能够直接生成相关员工的考勤报表，报表能导出系统应采用模块程序设计，便于组合和修改综合考虑，确定本系统采用C/S工作模式，以oracle作为后
2、台数据库，C#为前台程序开发语言。3 系统功能模块划分3.1 员工信息管理模块3.2 考勤类型的设定模块3.3 员工考勤信息手工录入模块3.4 员工考勤情况统计报表生成模块二、数据库设计1 数据库需求分析与用户结合，调查用户需求操作的资料，弄清用户怎样处理各种数据资料，理清数据库中各数据之间的关系。通过分析，设计数据集和数据项如下：1.1 员工信息数据集，数据项为员工号，员工姓名，员工性别，员工所属部门。1.2 考勤类型数据集：数据项为类型号，类型名称1.3 员工考勤情况数据集：数据项为考勤日期，员工号，考勤类型号，备注。2 数据库结构设计2.1 员工信息实体E-R图2.2 考勤类型实体E-R
