数据库系统中安全代理访问技术的分析

several group 户方的数据库访问请求都通过数据库安全访问代理进行转发。客户方数据访问代理用于接收所有的客户应用数据库访问请求(包括数据库客户的连接建立和连接断开请求)，并负责向数据库客户传送数据库访问的结果。数据库访问请求是按照协议格式化为数据报提供给数据加密/认证客户端，而数据库访问结果是按照协议
格式由数据加密/认证客户端提供。数据加密认证客户端完成客户端的数据加密和认证工作，同服务器端的数据加密/认证服务器一起完成强大的数据加密功能保障数据安全。数据加密/认证服务

several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
