You're going to have three classes that all map back to the same table, so you need a way to keep each class uniquely named. (This is something that is not likely to happen in a real application.)
因为将会有三个类全部映射回相同的表中，因此需要有一种方式来将每一个类单独命名(这在真实的应用程序中不大可能会发生)。
Query Q3 (5predsome) has multiple predicates and USES three side tables plus the main table, so it needs to compute a four-way join.
查询Q3 (5predsome)具有多个谓词、使用3个索引表和主表，因此它需要计算一个4路结合。
This way, please. Let us find a table for three.
请往这边走，咱们找个可坐三个人的桌子。
