Java阳光酒店管理系统附设计文档，数据库基于SQLSERVER2000，在源码包内备份有MDF文件，测试调试请先附加好。本Java酒店管理系统是一个完整的JAVA毕业设计作品，含有设计文档、说明书和用户需求书。由清华IT学习认证中心1123班顾俊小组成员顾竣董丰共同完成。运行截图为系统运行主框架，实时显示房态信息。 　　酒店管理系统主要功能包括团体开单、散客开单、宾客结帐、客房预订、系统设置、网络设置、营业查询、客户管理等。

说明：  1. 定义了刀具和工件结点的接触，并定义为默认“硬接触” 2. 工件上表面定义了自接触，防止切屑穿透工件上表面 3. 有些情况下可能产生工件右边界的部分结点卷曲后进入上表面，可以额外定义工件上表面与右边界部分结点（在右边界上，但是被切下来的部分结点）的接触算法这样就不会穿透了。(1. Defined the contact between tool and workpiece node, and defined as the default "hard contact". 2. Self-contact is defined on the upper surface of the workpiece to prevent the chip from penetrating the upper surface of the workpiece 3. In some cases, part nodes of the right boundary of the workpiece may curl into the upper surface, and the contact algorithm between the upper surface of the workpiece and the right boundary part node (the part node on the right boundary, but the part node cut off) can be defined in addition, so as not to penetrate.)
