一、
COBOL（Common Business-Oriented Language）是一种历史悠久的高级编程语言，广泛应用于商业、金融和政府部门的信息系统中。尽管现代编程语言层出不穷，但COBOL因其稳定性和强大的数据处理能力，在许多企业中仍然占据重要地位。本文将探讨如何利用COBOL语言开发一个酒店管理系统，并实现客户偏好分析。
二、系统需求分析
在开发酒店管理系统之前，我们需要明确以下需求：
1. 数据收集：收集客户的基本信息、消费记录、入住偏好等。
2. 数据处理：对收集到的数据进行清洗、转换和整合。
3. 数据分析：分析客户数据，识别客户偏好。
4. 数据展示：将分析结果以图表或报告的形式展示给管理人员。
三、系统设计
1. 数据库设计
设计一个关系型数据库，包含以下表：
- 客户表（Customer）：存储客户基本信息。
- 消费记录表（Transaction）：存储客户消费记录。
- 入住偏好表（Preference）：存储客户入住偏好。
2. 系统架构
系统采用分层架构，包括数据访问层、业务逻辑层和表示层。
四、COBOL代码实现
以下是基于COBOL语言的酒店管理系统客户偏好分析的核心代码示例。
