Once the rows are sorted, the algorithm for joining the two tables is easy: the database server simply reads both sorted tables sequentially and merge all rows if they are matching.

一旦实现了对行的分类，连接两个表的算法就十分容易：数据库服务器仅仅连续地读取两个已分类表，并合并所有相匹配的行。

There are several ways to map the identity, such as looking it up from a database, using an algorithm, and so on; these techniques are beyond the scope of this document.

可以通过几种方法来对标识进行映射，如在数据库中进行查找、使用一种算法、等等；这些技术超出了本文的讨论范围。

youdao

All values in a specific column of a database table are encrypted with the same password provided by the user, the same encryption algorithm, and the same cipher mode.

一个数据库表中某个特定列中的所有值都以用户提供的相同密码、相同的加密算法和相同的加密方式进行加密。

youdao

This is of course not the case, when a password database is lost and when an obsolete encryption algorithm like DES is used, users can not share blame.

Well, that really does not make much of a difference when you expose the entire database table and have way too much faith in the 34 year old encryption algorithm reported to be used to safeguard the data.
