1 transaction service
"A program that enables real-time, synchronous communication between the POS, the store database, and the head office database." -
2 transaction log file
"A file that contains a record of the changes that were made to an Exchange database. All changes to the database are recorded in the transaction log files before they are written into the database files. If a database shuts down unexpectedly, unfinished transactions can be restored by replaying the transaction log files into the database." -
3 transaction
A data manipulation action processed by a database. -
4 principal database
"In database mirroring, a read-write database whose transaction log is continuously sent to the mirror server, which restores the log to the mirror database." -
5 deferred transaction
A transaction that is not committed when the roll forward phase of recovery completes and that cannot be rolled back during database startup because data needed by roll back is offline. This data can reside in either a page or a file. -
6 primary database
"In a log shipping, a read-write database whose transaction log is backed up at regular intervals for restoring onto one or more secondary databases." -
7 TS
"A program that enables real-time, synchronous communication between the POS, the store database, and the head office database." -
8 log shipping job
"A job performing one of the following log-shipping operations: backing up the transaction log of the primary database at the primary server (the backup job), copying the transaction log file to a secondary server (the copy job), or restoring the log backup to the secondary database on a secondary server (the restore job). The backup job resides on the primary server; the copy and restore jobs reside on each of the secondary servers. See also: primary database, primary server, secondary database, secondary server." -
9 recovery
"A phase of database startup that brings the database into a transaction-consistent state. Recovery can include rolling forward all the transactions in the log records (the redo phase) and rolling back uncommitted transactions (the undo phase), depending on how the database was shut down." -
10 log chain
"A continuous sequence of transaction logs for a database. A new log chain begins with the first backup taken after the database is created, or when the database is switched from the simple to the full or bulk-logged recovery model. A log chain forks after a restore followed by a recovery, creating a new recovery branch." -
11 reset
"To archive the transaction history of a computer running FlexGo technology in the Provisioning Server database, and then register the computer, starting a new transaction history." -
12 recovery model
"A database property that controls the basic behavior of backup and restore operations for a database. For instance, the recovery model controls how transactions are logged, whether the transaction log requires backing up, and what kinds of restore operations are available."
