应用程序可能需要事务化方法，其中设备将提交更新多个后端系统(而不是单个数据库)的事务。
From a data-persistence standpoint, the fastest way to perform a database update operation is to use local transactions combined with database stored procedures.
从数据持久化的角度看，进行数据库更新操作的最快速的方式是将本地事务与数据库存储过程一起使用。
It is important that this data is correctly protected from the competing requirements of those transactions that require read access, and those that require update access.

The write-behind configuration should be tuned to best match your environment with regards to the ratio of write transactions, the same record update frequency, and database update latency.
write - behind的配置可以调整，以满足自己的运行环境，这其中包括写事务的比例，相同记录更新的频率，以及数据库的更新延迟。
Because ObjectGrid only supports single-phase commit transactions, any update can only be performed in a single partition.
由于ObjectGrid只支持单阶段提交事务，因此任何更新都只能在单个分区内执行。
That is, if concurrent transactions update an entity bean with same primary key, updates could get lost.
如果并发事务用同样的主键更新实体bean 时，更新资料将会丢失。
The most important of these is a multi-site read/update called "new order" that makes up about 45% of all transactions.
其中最重要的事务是名为 “neworder” 的多站点读/更新事务，大约占所有事务的 45%。
If the placeTrade() method had used transactions, both of these activities would have been included in a single LUW, and the trade order would have been rolled back if the account update failed.
