5. e4:
EMF
technology
for
Eclipse
development
Eclipse
4
has
the
target
to
solve
some
of
the
pain
points
of
Eclipse
3.x
development.
The
major
enhancements
in
Eclipse
4.x
compared
to
Eclipse
3.x
are:
• The
Eclipse
applica0on
is
available
as
a
dynamic
model
at
development
and
run0me.
• Eclipse
4
supports
dependency
injec@on.
• Eclipse
widgets
can
be
styled
via
external
CSS
files,
similar
to
webpages.
• The
applica0on
model
is
decoupled
from
its
presenta0on,
e.g.
different
user
interface
toolkits,
e.g.
SWT
or
JavaFX,
can
be
used
to
render
the
model.

8. What
is
modeling
and
what
is
not?
For
us:
-­‐
to
draw
some
UML
diagrams
for
documenta@on
is
a
(limited)
form
of
modeling
…create
a
DSL

Xtext

GMF
is
modeling
What
is
model-­‐driven
development
and
what
is
not?
For
us
MDD
is
using
one
of
this:
-­‐ Automa@c
M2M
transforma@ons
-­‐ Code

-­‐ Run-­‐@me

it

19. Eclipse and Modeling
The survey
Some data
Conclusions

20. Modeling
in
Italy
It
is
relevant
(68%
uses
some
form
of
modeling).
There
is
a
certain
dissa0sfac0on
about
MD*
tools:
respondents
believe
that
available
tools
don’t
fit
today’s
industry
needs
(35%
reported
at
least
one
problem
with
tools).
Maturity
does
not
seem
so
high:
many
use
modeling
just
for
documenta0on
or
to
generate
stubs
and
many
do
not
use
versioning.

21. How
to
improve
the
maturity?
Standardized
languages
are
the
key
to
the
diffusion
of
MD*
approaches;
UML
and
BPMN
are
posi@ve
examples
but
are
not
sufficient
because
they
do
not
cover
all
the
relevant
aspects
(e.g.
interac@ons
and
systems
communica@on).
MD*
usage
requires
integrated
toolsets
suppor@ng
the
full
development
process.
From
a
process
perspec@ve,
there
is
a
need
for
customized
processes
that
include
not
only
the
genera@on
but
also,
release
management,
versioning,
and
deployment.
From
a
more
general
perspec@ve,
focus
on
quan@ta@ve
aspects
of
soCware
produc@on
does
not
incen@ve
use
of
models,
which
can
be
exploited
when
quality
is
considered.
