Construction/Reconstruction of
Data
Element
Names
:
The
rules
provided
in
this
document
shall
be
applied
to
construction
of
data
element
names
for
new
data
requirements.
However,
in
some
cases
the
rules
may
also be
applied
to
reconstruction
of
names
for
existing
data
elements.
When
information
sharing
capability
and
compatibility
are
required,
data
element
names
must
adhere
to
the
same
principles
and
structural
rules;
otherwise
common
data
elements
cannot
be
identified
and
associated.
In
this
case,
the
established
rules
must
be
applied
to rename
existing
data
elements.
However,
the
integrity
and
comprehension
of
the
names
must
be
maintained.
In
addition,
reconstructed
names
from
existing
data
elements
can serve
as a baseline
for
the
development
of
data
elements
for
new
systems.
2.5
Enforceability
:
Automated
edit/validity
checks will
help
enforce
data
naming
standards. As
new
data
element
definitions
are
added
to
the
CG
DADS,
they
must
be edited
for
conformity
to
standards. Each
data
element
name
shall
be
subjected
to a
series
of
automated
tests. These
tests
shall
include:
o
Absence of
Class
Word
o
Absence of
Prime
Word
o
Minimum
Number
of
Words
(2)
o
Maximum
Number
of
Words
(9)
Tables
of
Prime
Words
and
Class
Words
shall
be
centrally
controlled
by
the
Data
Administration
staff,
G-SIA
and
made
available
in
edit
tables as a
part
of
the
automated
tools
for
construction/reconstruction
of
data
element
names.
As
new
standard
words
are
approved,
edit
tables
shall
be updated.
