 ### 1.1  整体背景
   随着旅游业的发展,以及世界商贸活动的频繁举行，其周边行业如酒店、餐饮、娱乐等行业也日趋发达。其中酒店宾馆组织庞大、服务项目多、信息量庞大，传统的人工管理方式已经无法满足要求。此时需要借助于计算机来进行现代化信息管理，从而提高服务质量和管理水平，同时降低管理成本。

 ### 1.3 业务背景
   传统的酒店管理往往需要酒店管理人花大量时间和精力来处理顾客查询、顾客登记等等事务。而错误的查询、繁琐的登记和结账手续、费用的结算错误、空余客房不能及时提供等等问题，可能导致顾客的频繁投诉，从而影响酒店的出租率。这些问题都可以通过计算机辅助系统来解决。酒店管理的信息化，不仅是酒店现代化形象的标志，而且能够酒店员工的工作效率，加速资金周转、降低各项成本以及改善服务质量。并支持客户直接在线预订,为客户提供方便快捷的服务.

 ### 2.1 问题说明
 由于酒店的客房有不同的档次，所以需要能够对客房进行分类处理。同时为了方便对客房价格的设置，需要提供一个能够对不同档次的客房能够进行预订价格、预订折扣、计时最低价格等的设置。需要提供一个客房设置功能，用来设置酒店的所有客房信息。在设置客房信息时，应该提供对不同房间的实际价格、实际折扣的设置。特别重要的是能够对房间的状态以及是否可用进行设置，这样能够方便酒店对客房的及时管理。需要提供一个入住登记和结账功能，并且能够对客户的登记时间、离店时间、客户资料、入住房间等信息进行登记。需要提供一个预定中心，能够处理客户的各种预定，如电话预定、总台面约、网上预定以及领导安排等等预定方式。需要提供一个客户管理功能，从而实现对酒店的客户信息的统一管理。最后还需要提供一个业务统计报表功能，能够对酒店一年中每月的住宿率进行统计，然后生成柱状图进行显示。
