81 Windows Internal Database
A relational data store that's included in Windows and is used by several Windows Services. -
82 mirroring
"Immediately reproducing every update to a read-write database (the principal database) onto a read-only mirror of that database (the mirror database) residing on a separate instance of the database engine (the mirror server). In production environments, the mirror server is on another machine. The mirror database is created by restoring a full backup of the principal database (without recovery)." -
83 log shipping
"Copying, at regular intervals, log backup from a read-write database (the primary database) to one or more remote server instances (secondary servers). Each secondary server has a read-only database, called a secondary database, that was created by restoring a full backup of the primary database without recovery. The secondary server restores each copied log backup to the secondary database. The secondary servers are warm standbys for the primary server." -
84 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." -
85 export
"To output data and database objects to another database, spreadsheet, or file format so another database, application, or program can use the data or database objects. You can export data to a variety of supported databases, programs, and file formats."يصدّر -
86 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." -
87 mirror server
"In a database mirroring configuration, the server instance where the mirror database resides. The mirror server is the mirroring partner whose copy of the database is currently the mirror database. The mirror server is a hot standby server." -
88 seed
"To add a database, either a blank database or a copy of the production database, to the storage group copy. This becomes the baseline database for the passive copy of the storage group." -
89 switchover
"An administrator-initiated action in which one or more passive copies of the mailbox database are being activated and designated as the active copy. An administrator can perform a database switchover, which is the activation of a single mailbox database copy, or an administrator can perform a server switchover, which is the activation of multiple mailbox database copies." -
90 DRDA
"A connection protocol for distributed relational database processing used by IBM relational database products that comprises protocols for communication between an application and a remote database, and communication between databases. DRDA also provides the connections for remote and distributed processing. The Distributed Data Management Architecture provides the base architecture for DRDA." -
91 exclusive
"Pertaining to a type of access to data in a database that is shared over a network. When you open a database in exclusive mode, you prevent others from opening the database." -
92 front-end/back-end application
"An application consisting of a ""back-end"" database file that contains tables, and copies of a ""front-end"" database file that contain all other database objects with links to the back-end tables."التطبيق الموجود على الكمبيوتر العميل/الخادمEnglish-Arabic terms dictionary > front-end/back-end application

93 ar-sa ODBC
"A program file used to connect to a particular database. Each database program, such as Access or dBASE, or database management system, such as SQL Server, requires a different driver." -
94 ODBC driver
"A program file used to connect to a particular database. Each database program, such as Access or dBASE, or database management system, such as SQL Server, requires a different driver." -
95 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." -
96 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." -
97 secondary server
"In a log shipping configuration, the server instance where the secondary database resides. At regular intervals, the secondary server copies the latest log backup from the primary database and restores the log to the secondary database. The secondary server is a warm standby server." -
98 simple recovery model
"A database recovery mode that minimally logs all transactions sufficiently to ensure database consistency after a system crash or after restoring a data backup. The database is recoverable only up to the time of its most recent data backup, and restoring individual pages is unsupported." -
99 piecemeal restore
"A composite restore in which a database is restored in stages, with each stage corresponding to a restore sequence. The initial sequence restores the files in the primary filegroup, and, optionally, other files, to any point in time supported by the recovery model and brings the database online. Subsequent restore sequences bring remaining files to the point consistent with the database and bring them online." -
100 principal server
"In database mirroring, the partner whose database is currently the principal database."
