酒店管理信息系统
2017.9
系统平台：Windows 2000
数据库服务器：Microsoft SQL Server 2000 开发工具：Visual Basic 6.0 系统开发人员：
⒈编写目的
酒店在正常的运营中需要对客房资源、顾客信息、结算信息进行管理，利用宾馆管理信息系统及时了解各个环节中信息的变更，有利于提高管理效率。
⒉系统功能分析
系统开发的总体任务是实现宾馆各种信息的系统化、规范化和自动化。 主要完成功能：
● 有关客房标准的制定、标准信息的输入，包括标准编号、标准名称、房间面积、床位数量、住房单价、是否有空调、电视机、电话以及单独卫生间等。 ● 客房标准信息的修改、查询等。
● 客房基本信息的输入，包括客房编号、客房类型、客房位置、客房单价、备注等。
● 客房基本信息的查询、修改，包括客房编号、客房类型、客房位置、客房单价、备注等。
● 剩余客房信息的查询等。
● 订房信息的输入，包括客房编号、客房种类、客房位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、备注信息等。 ● 订房信息的修改和查询，包括客房编号、客房种类、客房位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、备注信息等。
● 结算信息的输入，包括客房编号、客房种类、位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、结算日期、备注信息等。 ● 结算信息的修改和查询，包括客房编号、客房种类、客房位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、结日期、备注信息等。
⒊系统功能模块设计
按结构化程序设计思想，分析得出如下系统功能模块图
图Ⅰ系统功能模块图
⒋数据库设计
数据库设计步骤： ● 数据库需求分析
● 数据库概念结构设计 ● 数据库逻辑结构设计 ①数据库需求分析
分析调查有关宾馆管理信息需求的基础上得本系统所处理的数据流程
图Ⅱ 宾馆管理信息系统数据流程图
针对一般宾馆管理信息系统的需求，通过对宾馆管理过程的内容和流程分析，设计如下面所示的数据项和数据结构：
● 客房标准信息，包括的数据项有：标准编号、标准名称、房间面积、床位
数量、住房单价、是否有空调、电视、电话、单独卫生间等。
● 客房信息，包括的数据项有：客房编号、客房种类、客房位置、客房单价、
备注等。
● 订房信息，包括的数据项有：订房编号、客房编号、客房种类、客房位置、
客房备注信息、顾客姓名、顾客身份证号码、入住时间、折扣、备注等。 ● 结算信息，包括的数据项有：订房编号、客房编号、客房种类、客房位置、
客房备注信息、顾客姓名、顾客身份证号码、入住时间、折扣、结算时间、备注等。
②数据库概念结构设计
本系统根据以上的设计规划出的实体有：客房标准信息实体、客房信息实体、订房信息实体、结算信息实体。各个实体具体的描述Ｅ-Ｒ图如下：
客房标准信息实体Ｅ-Ｒ图
客房信息实体Ｅ-Ｒ图
订房信息实体Ｅ-Ｒ图
结算信息实体Ｅ-Ｒ图
实体之间关系Ｅ-Ｒ图
③数据库逻辑结构设计
首先将宾馆管理信息系统的数据库概念结构转化为SQL 2000数据库系统所支
⒌数据库结构的实现
利用SQL 2000数据库系统中的查询分析实现数据库的逻辑结构，其表格如下：
创建系统用户表格 user_Info
CREATE TABLE [dbo].[user_Info1](
[user_ID][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [user_PWD] [char] (10) COLLATE Chinese_PRC_CI_AS NULL, [user_Des] [char](10) COLLATE Chinese_PRC_CI_AS NULL ) ON [PRIMARY]
创建客房标准信息表格 roomtype CREATE TABLE [dbo].[roomtype](
[typeid][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [typename][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [area][numeric](5,0) NULL, [bednum][numeric](2,0) NULL,
[haircondition][char](2) COLLATE Chinese_PRC_CI_AS NULL, [htelephone][char](2) COLLATE Chinese_PRC_CI_AS NULL, [htelevision][char](2) COLLATE Chinese_PRC_CI_AS NULL, [htoilet][char](2) COLLATE Chinese_PRC_CI_AS NULL, [price][numeric](10,2)NULL ) ON [PRIMARY]
创建客房信息表格 rooms
CREATE TABLE [dbo].[rooms](
[roomNO][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL,
[roomtype][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [roomposition][char](20) COLLATE Chinese_PRC_CI_AS NULL, [roomprice][numeric](10,2) NULL,
[putup][char](2) COLLATE Chinese_PRC_CI_AS NOT NULL, [roommemo][text] COLLATE Chinese_PRC_CI_AS NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 创建订房信息表bookin
CREATE TABLE [dbo].[bookin](
[bookno][char](14) COLLATE Chinese_PRC_CI_AS NOT NULL, [customname][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [customID][char](18) COLLATE Chinese_PRC_CI_AS NOT NULL, [roomno][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [indate][datetime] NULL,

[inmemo][text] COLLATE Chinese_PRC_CI_AS NULL, [checkdate][datetime] NULL, [ammount][numeric](10,2) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
⒍宾馆管理信息系统具体程序实现
⑴创建公用模块 Module1.bas
添加公共数据操作函数，用以执行各种SQL 语句。添加函数ExecuteSQL ，代码如下：
Public Function ExecuteSQL(ByValSQL As String,MsgString AsString)_
As ADODB.Recordset
‘执行SQL 语句，并返回记录集对象 Dim cnn As ADODB.Connection Dim rst As ADODB.Recordset Dim sTokens() As String ‘异常处理
On Error GoTo ExecuteSQL_Error’
‘用Split 函数产生一个包含各个子串的数组 sTokens=Split(SQL)
Set cnn=NEW ADODB.Connection ‘打开连接
cnn.Open ConnectString
If InStr(“INSERT,DELETE,UPDATE”,UCase$(sTokens(0))) Then Cnn.Execute SQL
MsgString=sTokens(0)&”query successful” Else
Set rst=NEW ADODO.Recordset
rst.Open Trim$(SQL),cnn,adOpenKeyset,adLockOptimistic rst.MoveLast get RecordCount
‘返回记录集对象
Set ExecuteSQL=rst
MsgString=”查询到”&rst.RecordCount&”条记录” End If
ExecuteSQL_Exit: Set rst=Nothing Set cnn=Nothing Exit Function ExecuteSQL_Error:
MsgString=”查询错误:”&Err.Description Resume ExecuteSQL_Exit End Function
Public Sub EnterToTab(Keyasc As Integer) ‘判断是否为回车键
If Keyasc=13 Then ‘ Keyasc用来保存当前按键 ‘转换成Tab 键 SendKeys”{TAB}” End If End sub
‘添加全局变量，用来记录各个窗口的读写状态，代码如下： Public flagTedit As Boolean ‘ 标示是否进入修改的窗体 Public flagRedit As Boolean Public flagBedit As Boolean Public flagCedit As Boolean Public gintCmode As Integer
Public gintTmode As Integer ’记录是添加还是修改状态，1为添加，2为修

酒店管理信息系统
2017.9
系统平台：Windows 2000
数据库服务器：Microsoft SQL Server 2000 开发工具：Visual Basic 6.0 系统开发人员：
⒈编写目的
酒店在正常的运营中需要对客房资源、顾客信息、结算信息进行管理，利用宾馆管理信息系统及时了解各个环节中信息的变更，有利于提高管理效率。
⒉系统功能分析
系统开发的总体任务是实现宾馆各种信息的系统化、规范化和自动化。 主要完成功能：
● 有关客房标准的制定、标准信息的输入，包括标准编号、标准名称、房间面积、床位数量、住房单价、是否有空调、电视机、电话以及单独卫生间等。 ● 客房标准信息的修改、查询等。
● 客房基本信息的输入，包括客房编号、客房类型、客房位置、客房单价、备注等。
● 客房基本信息的查询、修改，包括客房编号、客房类型、客房位置、客房单价、备注等。
● 剩余客房信息的查询等。
● 订房信息的输入，包括客房编号、客房种类、客房位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、备注信息等。 ● 订房信息的修改和查询，包括客房编号、客房种类、客房位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、备注信息等。
● 结算信息的输入，包括客房编号、客房种类、位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、结算日期、备注信息等。 ● 结算信息的修改和查询，包括客房编号、客房种类、客房位置、客房单价、顾客姓名、顾客身份证号码、入住日期、折扣、结日期、备注信息等。
⒊系统功能模块设计
按结构化程序设计思想，分析得出如下系统功能模块图
图Ⅰ系统功能模块图
⒋数据库设计
数据库设计步骤： ● 数据库需求分析
● 数据库概念结构设计 ● 数据库逻辑结构设计 ①数据库需求分析
分析调查有关宾馆管理信息需求的基础上得本系统所处理的数据流程
图Ⅱ 宾馆管理信息系统数据流程图
针对一般宾馆管理信息系统的需求，通过对宾馆管理过程的内容和流程分析，设计如下面所示的数据项和数据结构：
● 客房标准信息，包括的数据项有：标准编号、标准名称、房间面积、床位
数量、住房单价、是否有空调、电视、电话、单独卫生间等。
● 客房信息，包括的数据项有：客房编号、客房种类、客房位置、客房单价、
备注等。
● 订房信息，包括的数据项有：订房编号、客房编号、客房种类、客房位置、
客房备注信息、顾客姓名、顾客身份证号码、入住时间、折扣、备注等。 ● 结算信息，包括的数据项有：订房编号、客房编号、客房种类、客房位置、
客房备注信息、顾客姓名、顾客身份证号码、入住时间、折扣、结算时间、备注等。
②数据库概念结构设计
本系统根据以上的设计规划出的实体有：客房标准信息实体、客房信息实体、订房信息实体、结算信息实体。各个实体具体的描述Ｅ-Ｒ图如下：
客房标准信息实体Ｅ-Ｒ图
客房信息实体Ｅ-Ｒ图
订房信息实体Ｅ-Ｒ图
结算信息实体Ｅ-Ｒ图
实体之间关系Ｅ-Ｒ图
③数据库逻辑结构设计
首先将宾馆管理信息系统的数据库概念结构转化为SQL 2000数据库系统所支
⒌数据库结构的实现
利用SQL 2000数据库系统中的查询分析实现数据库的逻辑结构，其表格如下：
创建系统用户表格 user_Info
CREATE TABLE [dbo].[user_Info1](
[user_ID][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [user_PWD] [char] (10) COLLATE Chinese_PRC_CI_AS NULL, [user_Des] [char](10) COLLATE Chinese_PRC_CI_AS NULL ) ON [PRIMARY]
创建客房标准信息表格 roomtype CREATE TABLE [dbo].[roomtype](
[typeid][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [typename][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [area][numeric](5,0) NULL, [bednum][numeric](2,0) NULL,
[haircondition][char](2) COLLATE Chinese_PRC_CI_AS NULL, [htelephone][char](2) COLLATE Chinese_PRC_CI_AS NULL, [htelevision][char](2) COLLATE Chinese_PRC_CI_AS NULL, [htoilet][char](2) COLLATE Chinese_PRC_CI_AS NULL, [price][numeric](10,2)NULL ) ON [PRIMARY]
创建客房信息表格 rooms
CREATE TABLE [dbo].[rooms](
[roomNO][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL,
[roomtype][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [roomposition][char](20) COLLATE Chinese_PRC_CI_AS NULL, [roomprice][numeric](10,2) NULL,
[putup][char](2) COLLATE Chinese_PRC_CI_AS NOT NULL, [roommemo][text] COLLATE Chinese_PRC_CI_AS NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 创建订房信息表bookin
CREATE TABLE [dbo].[bookin](
[bookno][char](14) COLLATE Chinese_PRC_CI_AS NOT NULL, [customname][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [customID][char](18) COLLATE Chinese_PRC_CI_AS NOT NULL, [roomno][char](10) COLLATE Chinese_PRC_CI_AS NOT NULL, [indate][datetime] NULL,
[discount][numeric](2,0) NULL,
[inmemo][text] COLLATE Chinese_PRC_CI_AS NULL, [checkdate][datetime] NULL, [ammount][numeric](10,2) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
⒍宾馆管理信息系统具体程序实现
⑴创建公用模块 Module1.bas
添加公共数据操作函数，用以执行各种SQL 语句。添加函数ExecuteSQL ，代码如下：
Public Function ExecuteSQL(ByValSQL As String,MsgString AsString)_
As ADODB.Recordset
‘执行SQL 语句，并返回记录集对象 Dim cnn As ADODB.Connection Dim rst As ADODB.Recordset Dim sTokens() As String ‘异常处理
On Error GoTo ExecuteSQL_Error’
‘用Split 函数产生一个包含各个子串的数组 sTokens=Split(SQL)
Set cnn=NEW ADODB.Connection ‘打开连接
cnn.Open ConnectString
If InStr(“INSERT,DELETE,UPDATE”,UCase$(sTokens(0))) Then Cnn.Execute SQL
MsgString=sTokens(0)&”query successful” Else
Set rst=NEW ADODO.Recordset
rst.Open Trim$(SQL),cnn,adOpenKeyset,adLockOptimistic rst.MoveLast get RecordCount
‘返回记录集对象
Set ExecuteSQL=rst
MsgString=”查询到”&rst.RecordCount&”条记录” End If
ExecuteSQL_Exit: Set rst=Nothing Set cnn=Nothing Exit Function ExecuteSQL_Error:
MsgString=”查询错误:”&Err.Description Resume ExecuteSQL_Exit End Function
Public Sub EnterToTab(Keyasc As Integer) ‘判断是否为回车键
If Keyasc=13 Then ‘ Keyasc用来保存当前按键 ‘转换成Tab 键 SendKeys”{TAB}” End If End sub
‘添加全局变量，用来记录各个窗口的读写状态，代码如下： Public flagTedit As Boolean ‘ 标示是否进入修改的窗体 Public flagRedit As Boolean Public flagBedit As Boolean Public flagCedit As Boolean Public gintCmode As Integer
Public gintTmode As Integer ’记录是添加还是修改状态，1为添加，2为修
改
Public gintRmode As Integer Public gintBmode As Integer Public flagSedit As Boolean ⑵系统用户管理模块的创建 用户管理模块主要实现： ·用户登陆。 ·添加用户。 ·修改用户
具体客房标准添加代码：
