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.

What  is  a  model  and  what  is  not  a  model?

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  with  Xtext  or  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  genera@on  -­‐  Run-­‐@me  model  interpreta@on/execu@on  

…but  it  is  complex  to  define  borders  and  our  ques0ons  tried  to  be  as  general  as  possible

16%  of  the  adopters  of  modeling  have  created  tools  (17  users).                The  most  used  technologies  for  developing  these  tools  are:    •  GMF  (6  users)  •  Xtext  (4  users)    

Techniques  used:  toolsmithing

“Experts  do  not  write  models,  they  validate  them”?  Debasish  Ghosh  (maybe)

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.      

Page 21: Eclipse Florence Day: Modeling in the Italian Industry

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.
