Why
are
we
here?
Decision
Support
System
and
graph
databases
CALabs
Barcelona
team
has
organically
developed
a
novel
technology
in
the
form
of
Decision
Support
System
as
a
part
of
MODAClouds
project.
Graph
database
community
is
evolving
and
there
lies
poten8al
to
use
the
DSS
technology
in
addressing
the
graph
database
selec8on
problem
Objec8ve
of
this
talk
is
to
start
brainstorming
in
the
community
about
possible
usage
of
the
technology
to
assist
and
enhance
the
use
of
graph
databases
in
enterprises

performed
• The

What
are

What
criteria
are
important
in
the
selec8on
of
(cloud)
graph
databases?
Who
makes
the
decisions
in
industry
to
select
a
par8cular
graph
database
technology
for
a
company?
How
does
the
graph
database
community
plan
to
manage
legi8mate
customer
concerns
such
as
preven8on
of
vendor
lock-­‐in
and
cloud
outages?
Is
the
synchroniza8on
of
mul8ple
graph
databases
provided
by
different
vendors
possible?
Is
gathering
data
with
respect
to
different
characteris8cs
that
define
the
quality
of
the
graph
database
an
important
concern?
How
could
a
DSS
help
for
cloud

selec8on?
