数据库安全技术，连接加密的数据库

数据库安全在实际中的应用

连接加密的 Access 数据库



实例说明



开发一些中小型软件时，通常都采用 Access 数据库，因为 Access

数据库体积小、比较方便。但该数据库的安全性比较低，为了防止非法

用户的入侵，通常需要为该数据库设置密码，以确保数据库中数据的安

全。本实例将对如何使用 C#连接加密的 Access 数据库进行详细讲解。

实例运行效果如图 20.1 所示。



关键技术



加密的 Access 数据库

本实例主要对 Access 数据库的连接方法进行讲解，在连接 Access

数据库时需要用到 OleDbConnection 类。下面对本实例中用到的关键技术进行详细讲解。
