Compiled Dictionary
System Dictionary includes two types of dictionaries which contain
metadata:
* Master Dictionaries. A master dictionary consists of a TurboIMAGE
database that can be accessed by all System Dictionary intrinsics and
SDMAIN commands. Because of its complexity, however, the response
time while using master dictionaries may be inadequate for some
subsystems, especially those that must read from the dictionary at
run-time.
* Compiled Dictionaries. A compiled dictionary contains metadata
extracted from a master dictionary. Like a compiled program, a
compiled dictionary cannot be modified. A compiled dictionary is
therefore a read-only dictionary that can be accessed by those System
Dictionary intrinsics and commands that only read dictionary
metadata.
Compiled dictionaries provide faster dictionary read access and are
intended to be used by subsystems and applications that need only to read
the metadata. A compiled dictionary is less complex than a master
dictionary and is compacted into one or more flat files. Therefore, it
requires less disc storage space and provides a more efficient means of
transporting dictionary data to other groups and accounts in the same
system, or other systems in a distributed network. For more information
about compiled dictionaries, see the SDUTIL utility of the HP System
Dictionary/XL General Reference Manual, Volume 2 (32256-90005).
