Sometimes applications are written with a fine-grained API layer, requiring the client to make multiple calls to the API layer for a single logical unit of work (LUW).

有时，应用程序是使用细粒度的api层编写的，这需要客户端向api层发起多个调用才能实现单个逻辑工作单元(LUW)。

Back to the original point: with the API layer transaction strategy, the client must not make multiple calls to the API layer in a single unit of work requiring a transaction.

回到原点：对于api层事务策略，客户机绝对不能在涉及事务的单一工作单元中对api层发出多个调用。
