transaction data set

If another transaction retrieves the data and sees that the flag is set by some other user, then it will, by convention, give a warning message to the user that the data is in use.

如果另外的事务检索数据并发现标记已被其他用户设置，那么它将按约定向用户发出数据正在被使用的警告消息。

For example, a J2EE transaction could be set to retrieve a message from a JMS provider, extract data from that message, and then attempt to update the database.

例如，可以建立一个J2EE事务来从一个JMS提供者那里获取一条消息，从该消息中提取数据，并尝试更新数据库。

Executing a transaction such as a transfer of funds between banking accounts can also generate new records in a data set.

执行交易(例如在银行帐户之间转帐)也可能在数据集中生成新的记录。
