Janitor Program:
An application that runs
at scheduled intervals to manage
business information by deleting,
transferring, or archiving online data
(such as email) that is at or past its
scheduled active life. Janitor programs
are sometimes referred to as
“agents”—software that runs autonomously
“behind the scenes” on user systems and
servers to carry out business processes
according to predefined rules. Janitor
programs must include a facility to
support disposition and process holds.
Java:
Sun Microsystems’ Java is
a platformindependent, programming
language for adding animation and other
actions to websites.
Jaz (or Jazz) Drive:
A removable disc drive. A
Jaz drive holds up to 2 GB of data.
Commonly used for backup storage as well
as everyday use.
JMS:
Jukebox Management
Software.
See
Jukebox.
Journal:
A chronological record of
data processing operations that may be
used to reconstruct a previous or an
updated version of a file. In database
management systems, it is the record of
all stored data items that have values
changed as a result of processing and
manipulation of the data.
Journaling:
A function of email
systems (such as Microsoft Exchange and
Lotus Notes) that copies sent and
received items into a second information
store for retention or preservation.
Because Journaling takes place at the
information store (server) level when
the items are sent or received, rather
than at the mailbox (client) level, some
messagerelated metadata, such as user
foldering (what folder the item is
stored in within the recipient’s
mailbox) and the status of the “read”
flag, is not retained in the journaled
copy. The Journaling function stores
items in the system’s native format,
unlike email archiving solutions, that
use proprietary storage formats designed
to reduce the amount of storage space
required. Journaling systems may also
lack the sophisticated search and
retrieval capabilities available with
many email archiving solutions.
JPEG (Joint Photographic
Experts Group):
A compression algorithm
for still images that is commonly used
on the web.
Jukebox:
A mass storage device
that holds optical discs and loads them
into a drive.
Jump Drive:
See
Key Drive.
