Clearly, there is a need for a mechanism whereby the actual user's identity and database privileges are used for database requests performed by the middle tier on behalf of that user.
显然，需要用一种机制来确保对于中间层代表用户执行的数据库请求，仅使用实际的用户身份和数据库权限。
It is not necessary to have server requests and responses coincide with user actions, such as a request for an update to a database record and a response that the update was successful.
服务器请求和响应不需要匹配用户操作，例如一个更新数据库记录的请求和一个更新成功的响应。

If you have pages with high response times because of a database or CPU bottleneck, it will limit the number of requests per second that each virtual user can issue.
如果您因为资料库或CPU瓶颈而有高回应时间的页面，这会限制每个虚拟使用者发出的每秒查询数目。
