用户标识 userID
[计] user identification
identification of user
- 必须有一种机制能够支持惟一的用户标识和身份验证。
There must be a mechanism in place to support unique user identification and authentication. - 中央工具在单一位置存储整个网络的用户标识和访问控制信息,并提供用于进行全面管理的界面。
Central tools store user identity and access control information for the entire network in a single location and provide screens to manage it all. - 本例中的模式是当第一个事务读取某个数据行时,它将加上时间戳和用户标识,这类似于悲观会话锁定的处理方式(稍后讨论)。
The pattern in this case is that when the first transaction reads a row it will "stamp" it with the identity of the user, similarly to how pessimistic session locking is handled (covered next).
