Read committed, Read uncommitted, Repeatable Read, Serializable.
提交读，未提交读，可重复读，可串行读。
Read committed -- The transaction can read data committed by other transactions.
Read committed（读已提交） ——事务可以读取由另一事务提交的数据。
Instead they will read the currently committed version of the row.
相反，它们会读取这一行的当前已经提交的版本。
A phantom read occurs when a transaction re-executes a query and finds a set of results changed since the last query due to another transaction that committed new data.
当事务再次执行查询，并发现一组结果自最后一次查询后由于另一个事务提交了新的数据而发生了更改，则会发生幻像读。
An unrepeatable read can occur when the transaction reads some data again and finds that it changed since the last read due to another transaction that modified this data and committed.
事务再次读取某数据时发现它自最后一次读操作之后由于另一个事务修改并提交了该数据而发生了更改，则会发生不可重读。
Now, a read transaction can access the currently committed and consistent image of rows that are incompatibly locked by write transactions without being blocked.
现在，读取事务可以访问当前提交的、连贯的行映像(写入事务以不兼容方式锁定)，而不会受到阻塞。
"We are absolutely committed to the privacy of our users and would like to assure you that we are treating this situation with the utmost seriousness," read the email sent to users.

For example, a collector might be invoked every minute to read a host's CPU utilization or read the total number of committed transactions from a transaction manager through a JMX interface.
例如，可以每分钟调用一次收集器来读取主机的cpu利用率，或通过JXM接口从事务管理器读取提交事务的总数。
A newly added "currently committed" locking syntax eliminates the conflict between read and write workloads so the database can deliver a true point-in-time response.
新增的“currentlycommitted”锁语法可以消除读和写工作负载之间的冲突，让数据库实现真正的时间点响应。
With Committed read isolation, it will give this error: 244: Could not do a physical-order read to fetch next row.
如果使用Committed read隔离级别，则会发生以下错误：244：couldnotdoaphysical - orderreadto fetch next row。
Read-Committed is the minimum level required for optimistic locking to work.
Read-Committed是乐观锁工作所需的最低级别。
I've always thought that READ_COMMITTED (DB2 calls it Cursor Stability (CS)) meant that you do NOT lock on reads, and that you only read the committed data.
我一直认为read_committed (DB 2调用游标稳定性(CS))意味着你不锁上读，那你只能读提交的数据。
