OrientaGon
plays
a
big
role
DoD
“SOA
is
so
strategic,
in
fact,
that
SOA
underlies
how
the
DoD
expects
to
achieve
its
mission
in
the
21st
century”

of
outstanding
complexity

7. Net
Centric
Warfare
• Robust
network
for:
improved
informaGon
sharing,
and
shared
situaGonal
awareness
• InformaGon
as
Strategic
Military
Asset
– The
right
informaGon,
at
the
place,
at
the
right
Gme
• Goal
is
to
achieve
Agile
InformaGon
• Represents
a
fundamental
shiT
in
military
culture,
away
from
powerful
compartmentalized
war
machines
and
toward
interconnected
units
operaGng
cohesively

9. WSDL
and
SOAP
WSDL
and
SOAP
were
never
designed
to
model
complex
interacGons.
The
limitaGons
include
no
standard
ways
to:
• Define
a
"unit
of
work"
spanning
mulGple
operaGon
invocaGons
(begin
/
end)
• Specify
the
sequence
in
which
operaGon
needs
to
be
invoked
• Correlate
operaGons
invocaGons
as
part
of
a
unit
of
work
• Specify
the
intent
of
a
SOAP
message
