新型真空镀膜设备数据库管理

The database management in a new vacuum coating equipment

新型真空镀膜设备计算机控制系统（ＺＤＣＣＳ）上位管理机中，数据库的设计是通过基于ＶｉｓｕａｌＣ＋＋所支持的开放数据库互连（ＯＤＢＣ）来实现的．ＯＤＢＣ是实现异构环境数据库访问的接口，利用ＯＤＢＣ，应用程序开发人员可对多种不同数据库中的数据进行存取、修改和查询．ＶｉｓｕａｌＣ＋＋１５以上版本的ＭＦＣ（微软基本类库）提供了一些数据库类支持ＯＤＢＣ．这些类和ＶｉｓｕａｌＣ＋＋面向对象的特性，简化了编写Ｗｉｎｄｏｗｓ环境下访问各种数据库应用程序的工作．

In the master of the computer system of the new type vacuum coating device,the design of database is realized by open database connectivity(ODBC)supported by Visual C ++ 1 5.ODBC is the interface for connecting different database,and by using it programmers can save,gain,modify and seek data.The MFC of Visual C ++ 1 5 or above editions provides ODBC classes,and in combination with object oriented characteristic of Visual C ++ ,they simplify the way of visiting database in Windows.
