用大数据库设计影院售票管理系统

一．系统概述；

1．设计需求；

现在中国大部分的家庭都喜欢在家里置办属于自己风格的家庭影院。但是，仍然有

很多人喜欢到电影院去看电影。因为家里的气氛毕竟不如影院好。所以，现代家庭影院的出现并不会让电影院没有生路。

每个社会服务系统都有自己的一套管理机制。当然，电影院也不除外。其实电影院的管理系统应该来说比其他的社会服务系统的管理要简单一点。电影院不外乎是引进电影，制定播放影片的时间表，买票，检票进场观看，还有就是一些数据管理方面的事。如工作人员管理，票务管理等等。为了工作机制简单有序，必然要引进一套管理系统。

2．需求分析；

具体而言，影院售票系统需要实现以下的需求：

（1） 能够对播放电影，工作人员，售票事宜，检票事宜，无用数据进行处理。 （2） 售票管理自然有专人负责，要处理各电影的电影票销售问题。当然包括退票问题，还有就是预订电影票其实也就相当于买票。两者可以当一回事处理。

（3） 检票管理事宜要完成观众进场时检票的事宜。其中包括了电影票的真假检测问题。 （4） 数据管理要处理电影的播放的次序，工作人员的管理，以及过期电影票的处理问题。

二．结构设计

职工类型 验证码 价格 电影号 电影名 电影票号 职工信息 座位号 上映时间 电影号 上映时间 电影 座位 电影名称 导演 座位编号 是否售出 主演 生产地 电影票 座位票价

职工号 职工密码 实用文档

三．设计说明

1．分析与创建数据库；

根据系统的功能分析结果，影院售票管理系统将会使用Microsoft SQL Sever 2000 作为后台的数据库管理系统。本管理系统是应用于电影院中，而且需要和数据库之间进行频繁数据交换，所以采用Microsoft SQL Sever 2000 作为后台的数据库管理系统。

在本管理系统中，需要掌握影库充实信息，职工管理信息，票务管理信息，此外，由于要进行职工管理，还需要掌握使用本系统的职工。表1存储硬库信息列表，表2存储了电影院座位的相关数据连接关系，表3存储了电影票销售情况管理，表4存储了系统使用者职工的相关情况的管理列表。

表1 影库管理表---MOVIES

字段名称 Movie_id actor actress producer palydate 字段名称 seatid price 数据类型 smallint Nvarchar Nvarchar Nvarchar datetime 数据类型 smallint float 字段大小 2 8 2 作用 座位号 票价 是否售出 字段大小 2 50 50 50 25 8 作用 电影号 电影名称 导演 主演 制片厂 上映时间 字段属性 必填字段 是 是 否 否 否 是 字段属性 必填字段 是 是 是 字段属性 字段大小 2 2 2 50 8 8 2 作用 电影票号 座位号 电影号 电影名 上映时间 价格 验证码 必填字段 ticketsid seatid Movie_id palydate price smallint smallint smallint datetime float 是 是 是 否 是 是 是 有（无重复） 有 有 无 无 无 无 是 是 索引 是否主键 有（无重复） 无 无 是 索引 是否主键 有（无重复） 无 无 无 无 无 Movie_name Nvarchar 索引 是否主键 是 表2 电影院座位管理表---SEATS soldornot smallint 字段名称 数据类型 表3 电影票信息表---TICKETS Movie_name Nvarchar yanzhengma smallint

实用文档

表4 职工信息表---WORKERS

字段名称 workerid password leibie 根据规范化的设计理念，本管理系统的数据分成上面4个表，减少了数据的冗余，同时在这些表之间又存在着一些关联关系。这四个表之间的这两种关系表现在下图所示的关系：

数据类型 smallint smallint smallint 字段大小 2 2 2 作用 职工号 职工密码 职工类型 字段属性 必填字段 是 是 是 索引 无 无 无 是否主键 是

3．创建票务界面

（1）创建模块的功能

对所售出的电影票进行管理，把没用的数据进行清除 （2）创建模块的设计

在工程中添加一个窗体，命名为“影库系统”，用来作为影库系统窗体。界面 的设计如下图所示。

（3）代码编写

Imports System.Data.SqlClient

Public Class Form9
