So the type of connection being established does not matter because the act of booting the database will recover any incomplete transactions in the transaction log in order to preserve data integrity.
所以正在建立的连接的类型无关紧要，因为数据库的启动将恢复事务日志中所有未完成的事务，以便保持数据完整性。
RECOVER will do the RESTORE of the most recent backup, followed by a log apply process to bring the table space or database to a specified point in time.
RECOVER会恢复最近的备份，然后执行一个日志应用进程，将表空间或数据库带到一个指定的数据点。
For example, to recover data to the end of business day Wednesday, you would need the delta backup images for Monday, Tuesday, and Wednesday (or Wednesday's log files).
例如，为了将数据恢复到星期三工作结束时，需要星期一、星期二和星期三的差异备份镜像(或星期三的日志文件)。
