我们着眼于传统的事务处理和通过在动作集合上强制实行 all-or-none 语义来在许多动作间保持数据完整性的方法。

We looked at classical transaction processing and how it enables data integrity across a number of actions by forcing an all-or-none semantic to the set of actions.

一项隐含的DB 2限制会强制要求bus_start值小于bus_end值，确保时态数据的完整性。

An implicit DB2 constraint enforces that bus_start values are less than bus_end values, ensuring temporal data integrity.
