In strong coherence, data updating is done by the protocol of distributed transaction, this protocol must fulfil ACID. Weak coherence aim at copy replication.
针对分布式数据库的要求,分布式数据更新有强一致性和弱一致性之分,强一致性的数据更新是通过分布式事务的协议进行,这个协议必须满足ACID特性;弱一致性主要体现在数据副本复制上。

When faced with this idea, the temptation is to assume that you need some sort of distribution or replication mechanism that will copy the key/value pairs between the machines.
有了这个想法后,还有一种想当然是需要使用某种分配或复制机制来在机器之间复制键/值对。
Certain segments of DNA are being converted into RNA, and whereas in replication, you have to copy the whole genome, the whole - all of the chromosomes, all of the DNA contained in the chromosomes of the cell in order to completely replicate it; transcription only works on particular sequences of DNA.
特定的DNA序列被转录为RNA,在复制的过程中,整条染色体都被复制,包括其中的全部DNA序列,都被分毫不差地复制下来,以保证复制的完整性,而转录过程只发生在特定的DNA序列上
