   Hi,

   This Thursday, Anthony will report on his work done during his stay at
   CWI.

      Program transformations for data centered program reengineering

   Date:    15.01.04
   Time:    10:00
   Venue:   C001
   Speaker: Anthony Cleve
   Title:   Program transformations for data centered program reengineering

   The  LIBD team (FUNDP, Belgium) identifies six different strategies to
   migrate  data-intensive  applications  from  a  legacy Data Management
   System  (DMS)  to  a  modern  DMS. They consider 2 dimensions for this
   migration  :  the  database  conversion (D) and the program conversion
   (P).  The database conversion consists in deriving a new database from
   the  legacy  one.  The program conversion propagates the corresponding
   pertubation  to  the legacy program code. In the presentation, we will
   give  an  overview  of  our contribution to the second dimension : the
   program conversion. Here is the structure of the talk : First, we will
   introduce  two  global reengineering strategies : the Wrapper strategy
   (D2,P1)   and  the  Statement  Rewriting  strategy  (D1,P2).  We  will
   illustrate  these  strategies  by the conversion of Cobol files into a
   SQL database.

   Second,  we will describe two ASF+SDF specifications, implementing the
   program conversions (P1 and P2) in this particular case.

   Then,  we  will evaluate the suitability of the ASF+SDF technology for
   such Cobol transformations, and explore the future developments.

   The  programming environment meetings are a forum for the presentation
   and  discussion  of  new  ideas,  ongoing and finished work. A typical
   meeting  addresses  a subject in the area of programming environments,
   program  generation, algebraic specification, term rewriting, parsing,
   etc.  A presentation ideally takes between 45 and 90 minutes. Meetings
   taking  longer  than 45 minutes are interrupted by a coffeebreak. Most
   Thursdays,  a  meeting is held which starts at 10:00 am. in one of the
   rooms at CWI/WINS. Exceptionally, dates or times may change.

   The    program    of    the    meetings    is    available   on   WWW:
