Online Transaction Processing (OLTP)
Data processing that involves immediate access and updates to a database while the
user waits for the results. The database is always up to date.
organized file
The data blocks in the file or table are in contiguous order, and the index and data
blocks have little or no wasted disk space.
primary key
A unique field in a record in a key-sequenced file.
RELOAD command
A FUP command that physically reorganizes a key-sequenced file or SQL object (table
or index only) online while allowing shared read/write access to the file or object.
slack
The amount of free space in data or index blocks.
spooler
A set of programs that acts as an interface between users (and user applications) and
the print devices of a system.
Transaction Monitoring Facility (TMF)
A database protection subsystem incorporated into the Guardian 90 operating system.
TMF helps maintain the consistency and integrity of a database that is updated by
concurrent transactions and protects data against damage caused by system media
failures.
