本系统有三种操作权限，其中，营业员只可以执行开台、点菜、买单及查询日收入操作；领班可以执行开台、点菜、买单、进货、添加新员工、日收入及月收入查询等操作；经理具有最高权限，除了领班及营业员的操作权限外，还可以设置员工权限、添加商品信息及菜式信息、备份与恢复数据库及初始化数据等操作。(The system has three operating authority, which can only be executed Founding salesperson, a la carte, pay and check daily revenue operations foreman can perform Founding, a la carte, pay, purchase, adding new employees, daily income and monthly income of inquiry operation manager with the highest authority, in addition to the foreman and the operating authority salesperson, you can also set permissions for employees, product information and dishes to add information, database backup and recovery, and initial data and other operations.)

定义Matrix矩阵类，定义矩阵类头文件matrix.h(Matrix matrix class definition, define matrix class header file matrix.h)

用数据库的方式操作excel文件，包括了读取文件的表名，字段名和数据，有详细的注释(Operate with the database excel documents, including a table read from the file name, field names and data have detailed notes)

mfc下封装的一个数据库类，用ado方式调用access数据库(a class of encapsulates the database, call the access database using ado way)

简要说明:直接通过DAO读、写Access文件 　　 直接利用DAO来创建、读写Access文件，总的说来，对比上篇<直接通过ODBC读、写Excel文件>来讲，要简单一些。在下面的示例中，我们将用到两种方法：SQL和DAO类涵数来混合实现它们，这样做的目地，我想可以使大家更加方便灵活的运用它们来完成你想要做的东西。在示例程序中默认指定创建数据库名为：Demo.mdb，内部表名为：DemoTable，写入两个字段：名字和年龄，采用和上一篇读写Excel类似的操作，你也可以根据自己需要来动态改变它们。 (Brief Description : DAO directly through reading, writing documents directly using Access to create DAO, Access document literacy, in general, compared to the previous chapter)

数据库基本功能都可以实现,删除,添加等等(this program is useful for people who want to develop database)

数据库访问,能帮助解决很多问题的！大家可以好好学习学习。(Database access, can help solve many problems! We can learn to learn.)

ip地址数据库格式，便于开发使用,很清晰.(ip address database format to facilitate development and use, very clear.)

VC数据库，网络综合实例综合运用，包括文件读写，SHELL脚本打开文件，对SQL Server2000的ADO访问！(VERY GOOD！)

说明：  一个国外人用Microsoft Visual C++开发的小数据库。可以看看。这是他工作的东西哦。(a foreign people using Microsoft Visual C development of a small database. Look. This is the work of the things he Oh.)
