酒店管理系统高级功能示例：COBOL 语言实现

COBOL（Common Business-Oriented Language）是一种历史悠久的高级编程语言，最初设计用于商业、金融和行政系统。尽管现代编程语言如Java、Python等在流行，但COBOL仍然在一些大型企业中发挥着重要作用，特别是在需要处理大量数据的老旧系统中。本文将围绕COBOL语言，展示一个酒店管理系统的部分高级功能实现。

系统概述

酒店管理系统是一个复杂的软件系统，它需要处理客户预订、房间管理、账单处理、员工管理等众多功能。以下是一个基于COBOL语言的酒店管理系统高级功能示例。

1. 客户预订管理

客户预订管理是酒店管理系统的核心功能之一。以下是一个简单的COBOL程序，用于处理客户预订。

PROCESS-BOOKING.
PERFORM READ-NEXT-RECORD UNTIL END-OF-FILE
OR WS-CUST-ID = "END".

IF WS-CUST-ID NOT = "END"
DISPLAY "Customer ID: " WS-CUST-ID
DISPLAY "Customer Name: " WS-CUST-NAME
DISPLAY "Room Number: " WS-CUST-ROOM-NUMBER
DISPLAY "Arrival Date: " WS-CUST-ARRIVAL-DATE
DISPLAY "Departure Date: " WS-CUST-DEPARTURE-DATE
END-IF.

CLOSE CUSTOMER-FILE.

READ-NEXT-RECORD.
READ CUSTOMER-FILE INTO WS-CUSTOMER-RECORD
AT END SET END-OF-FILE TO TRUE.

TERMINATE-PROGRAM.
STOP RUN.

2. 房间管理

房间管理功能包括房间状态查询、房间分配和房间释放等。以下是一个简单的COBOL程序，用于处理房间分配。

cobol
IDENTIFICATION DIVISION.
PROGRAM-ID. ROOM-MANAGEMENT.

ENVIRONMENT DIVISION.
INPUT-OUTPUT SECTION.
FILE-CONTROL.
SELECT ROOM-FILE ASSIGN TO "ROOMS.DAT"
ORGANIZATION IS SEQUENTIAL.

DATA DIVISION.
FILE SECTION.
FD ROOM-FILE.
01 ROOM-RECORD.
05 ROOM-NUMBER PIC X(5).
05 ROOM-STATUS PIC X(10).

WORKING-STORAGE SECTION.
01 WS-ROOM-NUMBER PIC X(5).
01 WS-ROOM-STATUS PIC X(10).

PROCEDURE DIVISION.
PERFORM INITIALIZE-FILE
PERFORM ROOM-ASSIGNMENT
PERFORM ROOM-FREE
PERFORM TERMINATE-PROGRAM.

INITIALIZE-FILE.
OPEN INPUT ROOM-FILE.

ROOM-ASSIGNMENT.
PERFORM READ-NEXT-RECORD UNTIL END-OF-FILE
OR WS-ROOM-NUMBER = "END".

IF WS-ROOM-NUMBER NOT = "END"
IF WS-ROOM-STATUS = "AVAILABLE"
DISPLAY "Room " WS-ROOM-NUMBER " is available."
ELSE
DISPLAY "Room " WS-ROOM-NUMBER " is not available."
END-IF
END-IF.

CLOSE ROOM-FILE.

ROOM-FREE.
PERFORM READ-NEXT-RECORD UNTIL END-OF-FILE
OR WS-ROOM-NUMBER = "END".

IF WS-ROOM-NUMBER NOT = "END"
IF WS-ROOM-STATUS = "OCCUPIED"
DISPLAY "Room " WS-ROOM-NUMBER " is free."
MOVE "AVAILABLE" TO WS-ROOM-STATUS
WRITE ROOM-RECORD FROM WS-ROOM-RECORD
END-IF
END-IF.

CLOSE ROOM-FILE.

READ-NEXT-RECORD.
READ ROOM-FILE INTO WS-ROOM-RECORD
AT END SET END-OF-FILE TO TRUE.

TERMINATE-PROGRAM.
STOP RUN.

3. 账单处理

账单处理是酒店管理系统的另一个重要功能。以下是一个简单的COBOL程序，用于处理账单生成。

cobol
IDENTIFICATION DIVISION.
PROGRAM-ID. BILLING-SYSTEM.

ENVIRONMENT DIVISION.
INPUT-OUTPUT SECTION.
FILE-CONTROL.
SELECT INVOICE-FILE ASSIGN TO "INVOICES.DAT"
ORGANIZATION IS SEQUENTIAL.

DATA DIVISION.
FILE SECTION.
FD INVOICE-FILE.
01 INVOICE-RECORD.
05 INVOICE-NUMBER PIC X(10).
05 CUST-ID PIC X(10).
05 TOTAL-AMOUNT PIC 9(10).99.

WORKING-STORAGE SECTION.
01 WS-INVOICE-NUMBER PIC X(10).
01 WS-CUST-ID PIC X(10).
01 WS-TOTAL-AMOUNT PIC 9(10).99.

PROCEDURE DIVISION.
PERFORM INITIALIZE-FILE
PERFORM GENERATE-INVOICE
PERFORM TERMINATE-PROGRAM.

INITIALIZE-FILE.
OPEN INPUT INVOICE-FILE.

GENERATE-INVOICE.
PERFORM READ-NEXT-RECORD UNTIL END-OF-FILE
OR WS-INVOICE-NUMBER = "END".

IF WS-INVOICE-NUMBER NOT = "END"
DISPLAY "Invoice Number: " WS-INVOICE-NUMBER

DISPLAY "Total Amount: " WS-TOTAL-AMOUNT
END-IF.

CLOSE INVOICE-FILE.

END-IF.

CLOSE EMPLOYEE-FILE.

READ-NEXT-RECORD.
